How can I avoid a InvalidCastException in .NET?

Question

Is there a way to check whether a C# cast will be successful? In some cases; based on how a rendered page is put together; inheriting from different Master Pages, some casts will work and others will not. I am wondering how I can check to see if a cast will be successful or if I just have to catch and handle an invalid cast exception.

Answer 1

You can say :

if (Variable is Typename) { 
}

Or

  Variable = OtherVariable as TypeName;

Variable will be null if casting was not possible.

Answer 2

alternatively, you can use "as" keyword to cast and check if the result is null.
