Performance, how heavy a try / catch? (. NET)

These days are entered into a discussion where we began to assess the "weight" of a try / catch block.
If a pure block try / catch, not used does not cost anything to use it incorrectly has an enormous weight.
To demonstrate this I used a code profiler and small. NET code that contained these two functions:



public static int NoCatch (object date) {

if (date != null)
    { return (int)data; }
    else
    { return 1; }
}


public static int WithCatch(object data)
{
    try
    {
        return (int)data;
} catch


{return 1;
}}






As you can see the function WithCatch (object data) uses the try to run a generic error condition, while the first block of code uses a simple if to avoid the error.
Well, what were the results? Here they are:


TryCatchTest.Program.TestNoCatch (int64, object): 0.17

TryCatchTest.Program.TestWithCatch (int64, object): 491.77

Well ... up to 10,000 processing method, nearly% of the time was used by the second function.
