Catch an exception thrown by an async void method

Question

Using the async CTP from Microsoft for .NET, is it possible to catch an exception thrown by an async method in the calling method?

public async void Foo()
{
         


        

Answer 1

The exception can be caught in the async function.

public async void Foo()
{
    try
    {
        var x = await DoSomethingAsync();
        /* Handle the result, but sometimes an exception might be thrown
           For example, DoSomethingAsync get's data from the network
           and the data is invalid... a ProtocolException might be thrown */
    }
    catch (ProtocolException ex)
    {
          /* The exception will be caught here */
    }
}

public void DoFoo()
{
    Foo();
}
