Visual Studio function to automatically create matching catch blocks for exceptions?

Question

Let's say I have the following method in C #:

XslCompiledTransform myObject;

public void foo() {
  try {
    myObject.Transform(input, output);
  } catch (???) {
  }
}

Is there an option or functionality in Visual Studio 2012 that automatically generates all the blocks catchfor exceptions that may occur in XslCompiledTransform? How to "Create catch blocks"?

Answer 1

No, there is no sensible way to automatically generate all catch blocks of all possible exceptions. But Visual Studio shows a list of related exceptions for calling the function, as shown below.

Usually try to catch them at the highest logical level, where you are flexible enough in your application to make a wither decision throwor handle it somehow.
