仅供我澄清:

我可以在.NET Framework中抛出CLS-Complaint和非CLS投诉异常吗？.我正在使用C#3.0.

当我抓住异常

catch(Exception ex)
{

}

• 它只会捕获CLS-Complaint异常吗？
• RuntimeWrappedException类有什么用(我可以举一个简单的例子吗？).

我有用C#编写的以下函数

public static string GetNominativeDeclension(string surnameNamePatronimic)
{
    if(surnameNamePatronimic == null) 
       throw new ArgumentNullException("surnameNamePatronimic");


IntPtr[] ptrs = null;
try
{
    ptrs = StringsToIntPtrArray(surnameNamePatronimic);

    int resultLen = MaxResultBufSize;
    int err = decGetNominativePadeg(ptrs[0], ptrs[1], ref resultLen);
    ThrowException(err);
    return IntPtrToString(ptrs, resultLen);
}
catch
{
    return surnameNamePatronimic;
}
finally
{
    FreeIntPtr(ptrs);
}

}


函数decGetNominativePadeg在非托管dll中 

[DllImport("Padeg.dll", EntryPoint = "GetNominativePadeg")]
private static extern Int32 decGetNominativePadeg(IntPtr surnameNamePatronimic,
    IntPtr result, ref Int32 resultLength);


并抛出异常:
