How to retrieve the LoaderException property?

Question

I get a error message while updating my service reference:

Custom tool warning: Unable to load one or more of the requested types. Retrieve the LoaderExceptions

Answer 1

catch (ReflectionTypeLoadException ex)
{        
    foreach (var item in ex.LoaderExceptions)
    {
          MessageBox.Show(item.Message);                    
    }
}

I'm sorry for resurrecting an old thread, but wanted to post a different solution to pull the loader exception (Using the actual ReflectionTypeLoadException) for anybody else to come across this.

Answer 2

Another Alternative for those who are probing around and/or in interactive mode:

$Error[0].Exception.LoaderExceptions

Note: [0] grabs the most recent Error from the stack

Answer 3

try
{
  // load the assembly or type
}
catch (Exception ex)
{
  if (ex is System.Reflection.ReflectionTypeLoadException)
  {
    var typeLoadException = ex as ReflectionTypeLoadException;
    var loaderExceptions  = typeLoadException.LoaderExceptions;
  }
}

Answer 4

Using Quick Watch in Visual Studio you can access the LoaderExceptions from ViewDetails of the thrown exception like this:

($exception).LoaderExceptions
