Incorrect stacktrace by rethrow

Question

I rethrow an exception with \"throw;\", but the stacktrace is incorrect:

static void Main(string[] args) {
    try {
        try {
            throw new Exce         


        

Answer 1

This is a well known limitation in the Windows version of the CLR. It uses Windows' built-in support for exception handling (SEH). Problem is, it is stack frame based and a method has only one stack frame. You can easily solve the problem by moving the inner try/catch block into another helper method, thus creating another stack frame. Another consequence of this limitation is that the JIT compiler won't inline any method that contains a try statement.
