if i put empty catch blocks for my c# code, is it going to be an equivalent for vb.net's "On Error Resume Next" statement
try
{
C# code;
}
[code]....
i have to convert a vb.net code to c#, and the old code has ~200 "On Error Resume Next" statements although i am using proper try {} catch {} in my new code, but just wanted to know if there is a better alternative.

I'm not talking about On Error Resume Next, that simply ignores the error. What I want to do is fix it, then continue with executing the procedure-but I can't find a way to do that, other than enclosing every single line of code in its own Try/Catch block. Nope, don't want to do that-isn't there another way?

I'm reading a dataset, if there are any issues with data, I log those errors to a table, but I need to continue reading the dataset with next record.
I am familiar with try/catch/finally for error handling. I'm reading the dataset in the try block, log the error in the 'catch' block. Now my question is - how do I continue with the loop again, since 'On Error Resume Next' statement is not supported in catch block VB.Net?

It seems that there is a glitch in Vb, While having some tasks ( Thread ) queued using Tasks if you try to use Invoke, the thread do not resume when the delegate returns.If BeginInvoke is used, it works but the problem is that it become impossible to execute a delegate synchronously.This does force the use of the AutoResetEvent to control the thread.The problem comes when the thread execute some code in a other classes, using a single AutoResetEvent within many classes just give a very dirty code.
