我尝试使用上面的建议，并在这个过程中改进了这个线程中的解决方案。

让我们假设您使用实现PropertyChanged事件的基类(在本例中为ObservableObject)，您将像这样做。有一天我可能会在我的博客上写一篇博客文章 sqljana.wordpress.com

我确实将类重命名为ObservableObject，并使用CallerMemberName属性利用了c# 5的一个特性

下面是你们会更喜欢的部分。我构建了一个Powershell脚本来为SQL数据库中的所有表生成。它是基于一个名为Chad Miller的Powershell大师的Invoke-SQLCmd2 cmdlet，可以从这里下载: http://gallery.technet.microsoft.com/ScriptCenter/7985b7ef-ed89-4dfd-b02a-433cc4e30894/

一旦有了cmdlet，为所有表生成的Powershell脚本就变得简单了(一定要用特定的值替换变量)。

. C:\MyScripts\Invoke-Sqlcmd2.ps1

$serverInstance = "MySQLInstance"
$databaseName = "MyDb"
$generatorSQLFile = "C:\MyScripts\ModelGen.sql" 
$tableListSQL = "SELECT name FROM $databaseName.sys.tables"
$outputFolder = "C:\MyScripts\Output\"
$namespace = "MyCompany.Business"

$placeHolderSchema = "&Schema"
$placeHolderTableName = "&TableName"
$placeHolderNamespace = "&Namespace"

#Get the list of tables in the database to generate c# models for
$tables = Invoke-Sqlcmd2 -ServerInstance $serverInstance -Database $databaseName -Query $tableListSQL -As DataRow -Verbose

foreach ($table in $tables)
{
    $table1 = $table[0]
    $outputFile = "$outputFolder\$table1.cs"


    #Replace variables with values (returns an array that we convert to a string to use as query)
    $generatorSQLFileWSubstitutions = (Get-Content $generatorSQLFile).
                                            Replace($placeHolderSchema,"dbo").
                                            Replace($placeHolderTableName, $table1).
                                            Replace($placeHolderNamespace, $namespace) | Out-String

    "Ouputing for $table1 to $outputFile"

    #The command generates .cs file content for model using "PRINT" statements which then gets written to verbose output (stream 4)
    # ...capture the verbose output and redirect to a file

Visual Studio杂志发表了这篇文章:

为SQL查询结果生成。net POCO类

它有一个可下载的项目，你可以构建，给它你的SQL信息，它会为你制作出类。

现在，如果该工具刚刚为SELECT、INSERT和UPDATE创建了SQL命令....

我无法让亚历克斯的答案在Sql Server 2008 R2上工作。所以，我用同样的基本原理重写了它。它现在支持模式，并且对列属性映射(包括将可为空的日期类型映射为可为空的c#值类型)进行了一些修复。下面是Sql语句:

   DECLARE @TableName VARCHAR(MAX) = 'NewsItem' -- Replace 'NewsItem' with your table name
    DECLARE @TableSchema VARCHAR(MAX) = 'Markets' -- Replace 'Markets' with your schema name
    DECLARE @result varchar(max) = ''

    SET @result = @result + 'using System;' + CHAR(13) + CHAR(13) 

    IF (@TableSchema IS NOT NULL) 
    BEGIN
        SET @result = @result + 'namespace ' + @TableSchema  + CHAR(13) + '{' + CHAR(13) 
    END

    SET @result = @result + 'public class ' + @TableName + CHAR(13) + '{' + CHAR(13) 

    SET @result = @result + '#region Instance Properties' + CHAR(13)  

   SELECT
      @result = @result + CHAR(13)
      + ' public ' + ColumnType + ' ' + ColumnName + ' { get; set; } ' + CHAR(13)
    FROM (SELECT
      c.COLUMN_NAME AS ColumnName,
      CASE c.DATA_TYPE
        WHEN 'bigint' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'Int64?'
            ELSE 'Int64'
          END
        WHEN 'binary' THEN 'Byte[]'
        WHEN 'bit' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'bool?'
            ELSE 'bool'
          END
        WHEN 'char' THEN 'string'
        WHEN 'date' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'DateTime?'
            ELSE 'DateTime'
          END
        WHEN 'datetime' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'DateTime?'
            ELSE 'DateTime'
          END
        WHEN 'datetime2' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'DateTime?'
            ELSE 'DateTime'
          END
        WHEN 'datetimeoffset' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'DateTimeOffset?'
            ELSE 'DateTimeOffset'
          END
        WHEN 'decimal' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'decimal?'
            ELSE 'decimal'
          END
        WHEN 'float' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'Single?'
            ELSE 'Single'
          END
        WHEN 'image' THEN 'Byte[]'
        WHEN 'int' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'int?'
            ELSE 'int'
          END
        WHEN 'money' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'decimal?'
            ELSE 'decimal'
          END
        WHEN 'nchar' THEN 'string'
        WHEN 'ntext' THEN 'string'
        WHEN 'numeric' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'decimal?'
            ELSE 'decimal'
          END
        WHEN 'nvarchar' THEN 'string'
        WHEN 'real' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'Double?'
            ELSE 'Double'
          END
        WHEN 'smalldatetime' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'DateTime?'
            ELSE 'DateTime'
          END
        WHEN 'smallint' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'Int16?'
            ELSE 'Int16'
          END
        WHEN 'smallmoney' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'decimal?'
            ELSE 'decimal'
          END
        WHEN 'text' THEN 'string'
        WHEN 'time' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'TimeSpan?'
            ELSE 'TimeSpan'
          END
        WHEN 'timestamp' THEN 'Byte[]'
        WHEN 'tinyint' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'Byte?'
            ELSE 'Byte'
          END
        WHEN 'uniqueidentifier' THEN CASE C.IS_NULLABLE
            WHEN 'YES' THEN 'Guid?'
            ELSE 'Guid'
          END
        WHEN 'varbinary' THEN 'Byte[]'
        WHEN 'varchar' THEN 'string'
        ELSE 'Object'
      END AS ColumnType,
      c.ORDINAL_POSITION
    FROM INFORMATION_SCHEMA.COLUMNS c
    WHERE c.TABLE_NAME = @TableName
    AND ISNULL(@TableSchema, c.TABLE_SCHEMA) = c.TABLE_SCHEMA) t
    ORDER BY t.ORDINAL_POSITION

    SET @result = @result + CHAR(13) + '#endregion Instance Properties' + CHAR(13)  

    SET @result = @result  + '}' + CHAR(13)

    IF (@TableSchema IS NOT NULL) 
    BEGIN
        SET @result = @result + CHAR(13) + '}' 
    END

    PRINT @result

它生成的c#代码如下所示:

using System;

namespace Markets
{
    public class NewsItem        {
        #region Instance Properties

        public Int32 NewsItemID { get; set; }

        public Int32? TextID { get; set; }

        public String Description { get; set; }

        #endregion Instance Properties
    }

}

It may be an idea to use EF, Linq to Sql, or even Scaffolding; however, there are times when a piece of coding like this comes in handy. Frankly, I do not like using EF navigation properties where the code it generates made 19,200 separate database calls to populate a 1000 row grid. This could have been achieved in a single database call. Nonetheless, it could just be that your technical architect does not want you to use EF and the like. So, you have to revert to code like this... Incidentally, it may also be an idea to decorate each of the properties with attributes for DataAnnotations, etc., but I'm keeping this strictly POCO.

编辑 修正了时间戳和Guid?

我将几个基于SQL的答案(主要是Alex Aza的根答案)打包到kassify中，这是一个控制台应用程序，可以一次性为指定的数据库生成所有类:

例如，给定一个Users表，它是这样的:

+----+------------------+-----------+---------------------+
| Id |       Name       | Username  |        Email        |
+----+------------------+-----------+---------------------+
|  1 | Leanne Graham    | Bret      | Sincere@april.biz   |
|  2 | Ervin Howell     | Antonette | Shanna@melissa.tv   |
|  3 | Clementine Bauch | Samantha  | Nathan@yesenia.net  |
+----+------------------+-----------+---------------------+

klassify将生成一个名为Users.cs的文件，看起来像这样:

    public class User 
    {
        public int Id {get; set; }
        public string Name { get;set; }
        public string Username { get; set; }
        public string Email { get; set; }
    }

它将为每个表输出一个文件。丢弃你不用的东西。

使用

 --out, -o:
        output directory     << defaults to the current directory >>
 --user, -u:
        sql server user id   << required >>
 --password, -p:
        sql server password  << required >>
 --server, -s:
        sql server           << defaults to localhost >>
 --database, -d:
        sql database         << required >>
 --timeout, -t:
        connection timeout   << defaults to 30 >>
 --help, -h:
        show help

是的，这些是伟大的，如果你使用一个简单的ORM像Dapper。

如果你使用。net，你可以在运行时使用WriteXmlSchema方法用任何数据集生成XSD文件。http://msdn.microsoft.com/en-us/library/xt7k72x8 (v = vs.110) . aspx

是这样的:

using (SqlConnection cnn = new SqlConnection(mConnStr)) {
DataSet Data = new DataSet();
cnn.Open();
string sql = "SELECT * FROM Person";

using (SqlDataAdapter Da = new SqlDataAdapter(sql, cnn))
{
try
{
    Da.Fill(Data);
    Da.TableMappings.Add("Table", "Person");
    Data.WriteXmlSchema(@"C:\Person.xsd");
}
catch (Exception ex)
{ MessageBox.Show(ex.Message); }
}
cnn.Close();

从那里，您可以使用xsd.exe创建一个可从开发人员命令提示符序列化XML的类。 http://msdn.microsoft.com/en-us/library/x6c1kb0s (v = vs.110) . aspx

是这样的:

xsd C:\Person.xsd /classes /language:CS
