{
    Insurance KR Users (Name)
}

但它捕获错误。请给我一个解决方案，包括这些类型的字符串转换为枚举。

but it catching errors. Please give me a solution to include these types of strings into enum.

推荐答案

在枚举成员本身必须是一个的有效的标识符，所以它不能包含空格或特殊字符。

The enum members itself must be a valid identifier, so it can't contain spaces or special characters.

但是你可以使用 DescriptionAttribute 为每个枚举值的更为完整的描述：

But you could use the DescriptionAttribute to provide a more complete description of each enum value:

public enum MemberGroup
{
    [Description("Insurance KR Users (Name)")]
    InsuranceKrUsers_Name
}

要检索的描述，可以使用这样的：

To retrieve the description, use something like this:

public static string GetDescription(Enum value)
{
   FieldInfo fi = value.GetType().GetField(value.ToString()); 
   DescriptionAttribute[] attributes = 
     (DescriptionAttribute[])fi.GetCustomAttributes(
     typeof(DescriptionAttribute), false);
   return (attributes.Length > 0) ? attributes[0].Description : value.ToString();
}
