Question

In my if statement below I need to check if in the first tables first row/column contains a string but I get an exception if the table has no rows.

the exception is:

“System.IndexOutOfRangeException = {“There is no row at position 0.”}”

Code snippet:

'if the table has no rows then an exception happens here
If myDataSet.Tables(0).Rows(0)(0).ToString <> "MyMessage" then


'do this - redirect

Else

 myDataSet.Tables(0).Rows(0)(0) = "no message"

End If

Can you help please?

Answer 1

It throws an exception because you’re assuming a row exists with the following statement If myDataSet.Tables(0).Rows(0)(0)

You should check that you have a row first by doing If myDataSet.Tables(0).Rows.Count > 0
