SeriousSamP 的答案很棒。我将代码移植到 C#。也许它对其他人有用。
只需将代码添加到新类；根据需要调整命名空间；在需要异常类型的文件中添加命名空间 using。
像这样称呼它：XmlSchemaExceptionErrorType myType = myException.GetSchemaErrorType();
这是移植的代码：
using System.Xml.Schema;
namespace MyNamespace.ClassExtensions
{
public static class XmlSchemaExceptionExtensions
{
/// <summary>
/// Get schema error type as enum. (This is only possible by reflection.)
/// </summary>
public static XmlSchemaExceptionErrorType GetSchemaErrorType(this XmlSchemaException exception)
{
string res = typeof(XmlSchemaException).GetField("res", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance).GetValue(exception) as string;
return (XmlSchemaExceptionErrorType)System.Enum.Parse(typeof(XmlSchemaExceptionErrorType), res);
}
/// <summary>
/// Error type enums of XmlSchemaException.
/// </summary>
public enum XmlSchemaExceptionErrorType
