try {}

catch {}

finally {}

Complete Simple Example

Here is a complete example using a button click event:

private void button6_Click(object sender, EventArgs e)
{
  try
  {
    MessageBox.Show("Before Error");
    int y = 0;
    y = 1 / y;
    MessageBox.Show("This line never executes: " + y);
  }
  catch
  {
    MessageBox.Show("you cannot divide by zero");
  }
  finally
  {
    MessageBox.Show("This line always executes.");
  }

}
