如果我理解正确，你需要一个从字符串到enum的转换:

enum GroupTypes {
    Unknown = 0,
    OEM = 1,
    CMB = 2
}
static GroupTypes StrToEnum(string str){
    GroupTypes g = GroupTypes.Unknown;
    try {
        object o = Enum.Parse(typeof(GroupTypes), str, true);
        g = (GroupTypes)(o ?? 0);
    } catch {
    }
    return g;
}
// then use it like this
GroupTypes g1 = StrToEnum("OEM");
GroupTypes g2 = StrToEnum("bad value");

如果您愿意，可以使用枚举类型的泛型使其更加花哨。

这里是扩展方法，我用来获得枚举值作为字符串。首先是枚举。

public enum DatabaseEnvironment
{
    [Description("AzamSharpBlogDevDatabase")]
    Development = 1, 
    [Description("AzamSharpBlogQADatabase")]
    QualityAssurance = 2, 
    [Description("AzamSharpBlogTestDatabase")] 
    Test = 3
}

Description属性来自System.ComponentModel。

这是我的扩展方法:

public static string GetValueAsString(this DatabaseEnvironment environment) 
{
    // get the field 
    var field = environment.GetType().GetField(environment.ToString());
    var customAttributes = field.GetCustomAttributes(typeof (DescriptionAttribute), false);

    if(customAttributes.Length > 0)
    {
        return (customAttributes[0] as DescriptionAttribute).Description;  
    }
    else
    {
        return environment.ToString(); 
    }
}

现在，你可以使用下面的代码访问枚举字符串值:

[TestFixture]
public class when_getting_value_of_enum
{
    [Test]
    public void should_get_the_value_as_string()
    {
        Assert.AreEqual("AzamSharpBlogTestDatabase",DatabaseEnvironment.Test.GetValueAsString());  
    }
}

在VS 2015中，你可以使用nameof

public class LogCategory
{
    public static string Trace;
    public static string Debug;
    public static string Info;
    public static string Warning;
    public static string Error;
}

用法:

Logger.Write("This is almost like an enum.", nameof(LogCategory.Info));

添加这个类

public class DatabasePreference {
    public DatabasePreference([CallerMemberName] string preferenceName = "") {
        PreferenceName = preferenceName;
    }
    public string PreferenceName;
}

这项工作使用CallerMemberName来最小化编码

使用:

//Declare names
public static DatabasePreference ScannerDefaultFlashLight = new DatabasePreference();
public static DatabasePreference ScannerQrCodes = new DatabasePreference();
public static DatabasePreference Scanner1dCodes = new DatabasePreference();

测试:

Console.WriteLine(ScannerDefaultFlashLight.PreferenceName);
Console.WriteLine(ScannerDefaultFlashLight.Scanner1dCodes);

输出:

ScannerDefaultFlashLight
Scanner1dCodes

使用类。

编辑:更好的例子

class StarshipType
{
    private string _Name;
    private static List<StarshipType> _StarshipTypes = new List<StarshipType>();

    public static readonly StarshipType Ultralight = new StarshipType("Ultralight");
    public static readonly StarshipType Light = new StarshipType("Light");
    public static readonly StarshipType Mediumweight = new StarshipType("Mediumweight");
    public static readonly StarshipType Heavy = new StarshipType("Heavy");
    public static readonly StarshipType Superheavy = new StarshipType("Superheavy");

    public string Name
    {
        get { return _Name; }
        private set { _Name = value; }
    }

    public static IList<StarshipType> StarshipTypes
    {
        get { return _StarshipTypes; }
    }

    private StarshipType(string name, int systemRatio)
    {
        Name = name;
        _StarshipTypes.Add(this);
    }

    public static StarshipType Parse(string toParse)
    {
        foreach (StarshipType s in StarshipTypes)
        {
            if (toParse == s.Name)
                return s;
        }
        throw new FormatException("Could not parse string.");
    }
}

您可以使用两个枚举。一个用于数据库，另一个用于可读性。

你只需要确保它们保持同步，这似乎是一个小成本。 你不必设置值，只是设置相同的位置，但设置值可以非常清楚地表明两个枚举是相关的，并防止错误重新排列枚举成员。注释让维护人员知道这些是相关的，必须保持同步。

// keep in sync with GroupTypes
public enum GroupTypeCodes
{
    OEM,
    CMB
}

// keep in sync with GroupTypesCodes
public enum GroupTypes
{
    TheGroup = GroupTypeCodes.OEM,
    TheOtherGroup = GroupTypeCodes.CMB
}

要使用它，你只需要先转换为代码:

GroupTypes myGroupType = GroupTypes.TheGroup;
string valueToSaveIntoDatabase = ((GroupTypeCodes)myGroupType).ToString();

然后，如果你想让它更方便，你可以添加一个扩展函数，只适用于这种类型的枚举:

public static string ToString(this GroupTypes source)
{
    return ((GroupTypeCodes)source).ToString();
}

然后你可以这样做:

GroupTypes myGroupType = GroupTypes.TheGroup;
string valueToSaveIntoDatabase = myGroupType.ToString();
