public string ObjectToXML(object input)
{
    try
    {
        var stringwriter = new System.IO.StringWriter();
        var serializer = new XmlSerializer(input.GetType());
        serializer.Serialize(stringwriter, input);
        return stringwriter.ToString();
    }
    catch (Exception ex)
    {
        if (ex.InnerException != null)
            ex = ex.InnerException;

        return "Could not convert: " + ex.Message;
    }
}

//Usage
var res = ObjectToXML(obj)

您需要使用以下类:

using System.IO;
using System.Xml;
using System.Xml.Serialization;

我修改了我的返回一个字符串，而不是像下面这样使用一个ref变量。

public static string Serialize<T>(this T value)
{
    if (value == null)
    {
        return string.Empty;
    }
    try
    {
        var xmlserializer = new XmlSerializer(typeof(T));
        var stringWriter = new StringWriter();
        using (var writer = XmlWriter.Create(stringWriter))
        {
            xmlserializer.Serialize(writer, value);
            return stringWriter.ToString();
        }
    }
    catch (Exception ex)
    {
        throw new Exception("An error occurred", ex);
    }
}

它的用法是这样的:

var xmlString = obj.Serialize();

下面是一个基本代码，可以帮助将c#对象序列化为xml:

using System;

public class clsPerson
{
  public  string FirstName;
  public  string MI;
  public  string LastName;
}

class class1
{ 
   static void Main(string[] args)
   {
      clsPerson p=new clsPerson();
      p.FirstName = "Jeff";
      p.MI = "A";
      p.LastName = "Price";
      System.Xml.Serialization.XmlSerializer x = new System.Xml.Serialization.XmlSerializer(p.GetType());
      x.Serialize(Console.Out, p);
      Console.WriteLine();
      Console.ReadLine();
   }
}    

扩展类:

using System.IO;
using System.Xml;
using System.Xml.Serialization;

namespace MyProj.Extensions
{
    public static class XmlExtension
    {
        public static string Serialize<T>(this T value)
        {
            if (value == null) return string.Empty;

            var xmlSerializer = new XmlSerializer(typeof(T));

            using (var stringWriter = new StringWriter())
            {
                using (var xmlWriter = XmlWriter.Create(stringWriter,new XmlWriterSettings{Indent = true}))
                {
                    xmlSerializer.Serialize(xmlWriter, value);
                    return stringWriter.ToString();
                }    
            }
        }
    }
}

用法:

Foo foo = new Foo{MyProperty="I have been serialized"};

string xml = foo.Serialize();

只是引用名称空间持有您的扩展方法在文件中，你想使用它，它将工作(在我的例子中，它将是:使用myproject . extensions;)

请注意，如果您想使扩展方法只特定于一个特定的类(例如。， Foo)，你可以在扩展方法中替换T参数。

序列化(这个Foo值){…}

    string FilePath = ConfigurationReader.FileLocation;   //Getting path value from web.config            
    XmlSerializer serializer = new XmlSerializer(typeof(Devices)); //typeof(object)
            MemoryStream memStream = new MemoryStream();
            serializer.Serialize(memStream, lstDevices);//lstdevices : I take result as a list.
            FileStream file = new FileStream(folderName + "\\Data.xml", FileMode.Create, FileAccess.ReadWrite); //foldername:Specify the path to store the xml file
            memStream.WriteTo(file);
            file.Close();

您可以创建结果并将其作为xml文件存储在所需的位置。

我有一个简单的方法来序列化一个对象到XML使用c#，它的工作很棒，它是高度可重用的。我知道这是一个较老的帖子，但我想发布这个帖子，因为有人可能会发现这对他们有帮助。

下面是我如何调用该方法:

var objectToSerialize = new MyObject();
var xmlString = objectToSerialize.ToXmlString();

下面是完成这项工作的类:

注意:由于这些是扩展方法，它们需要在静态类中。

using System.IO;
using System.Xml.Serialization;

public static class XmlTools
{
    public static string ToXmlString<T>(this T input)
    {
        using (var writer = new StringWriter())
        {
            input.ToXml(writer);
            return writer.ToString();
        }
    }

    private static void ToXml<T>(this T objectToSerialize, StringWriter writer)
    {
        new XmlSerializer(typeof(T)).Serialize(writer, objectToSerialize);
    }
}
