Checking if a datatable is null

Question

The following code is what I\'ve been using to retrieve user information from a sql database.

            string userName = LoginUser.UserName;
            strin         


        

Answer 1

It will be better if you use try catch for checking whether the table is empty or not , just handle the IndexOutOfRangeException exception.

Use the following logic:

try
{
   //dataTable operations
}
catch(IndexOutOfRangeException)
{
}

For me its working.
