Question

In following code I purposefully mistype “@fooData” to “@foo111Data” to check if the try statement is catching my exception. See below code. But the try/catch statement did not catch and display and exception in MessageBox, and VS2010 just break down and highlight the line of wrong code.

try
{
    conn.Open();
    cmd.Parameters.AddWithValue("@foo111Data", dataStrTb1.Text);
    cmd.ExecuteNonQuery();
}
catch (SqlCeException ex)
{
    MessageBox.Show(ex.ToString());
}
finally
{
    conn.Close();
}

Answer 1

Perhaps an exception of a different type is being thrown? I would suggest that you change the catch so that it just catches a general Exception, and see if it’s throwing another type.

Put a breakpoint in the catch statement, on the MessageBox.Show line, and then you can examine the Exception.
