I agree with Christian, this looks like converted VB6 code.

Here's the thing:

The "Err" object still exists in VB.NET, but it DOESN'T exist in C#.

What you need to do is like Christian suggested: Wrap your code in a try/catch statement:

try
{
//Your code goes here
}
catch (Exception ex)
{
//Error caught here, now use the properties of the Exception object, e.g. Discription:
string errorDiscription = ex.Discription;
}

Good luck

Another thing: Even though it is possible in .NET; I can't think of ANY reason where you would need to use "Goto", so try to avoid that in the future... Just a tip for better programming

So, what's your question? All you did was post some code. We can't just divine from thin air what you might want.

please post a logical code i am not getting it, all ya did is paste some code but tell us exactly what you want in this code just like the other programmers said use try catch which is a good practice to handle error in your application...

Which part of that is confusing you ?

This is obviously idiocy. Delete it, it does nothing, and is a poorly designed construct. Use a try catch instead. This looks to me like bad VB6 that someone converted to VB.NET and you're trying to move to C# by hand. Is that right ?
