Here is my case.

In unmamaged code, I wrote code as,

RaiseException(MYEXCETIONTYPE, ....);

Thereafter the exception finally got caught by managed code, and was
wired up to a .NET Exception object, you know.

managed code,

try
{
NativeCall();
}
catch (Exception e)
{
e.ToString(); //..
}

My purpose is to tell if it's a custom exception or a system
exception, that depends on if it's a MYEXCETIONTYPE. Then the problem
is how could I get the ExceptionCode?
Thanks.

Maybe Marshal.GetExceptionCode() can do?

try
{
NativeCall();
}
catch (MYEXCETIONTYPE e)
{
e.ExceptionCode ...
}
catch (Exception e)
{
e.ToString();
}
