I could really use some help with this assignment!

Must be a form application in C# also must be basic as I am a beginner.

The code that must be upgraded

private void btnCalculate_Click(object sender, EventArgs e) { decimal operand1 = Convert.ToDecimal(txtOperand1.Text); string operator1 = txtOperator.Text; decimal operand2 = Convert.ToDecimal(txtOperand2.Text); decimal result = Calculate(operand1, operator1, operand2);

result = Math.Round(result, 4); this.txtResult.Text = result.ToString(); txtOperand1.Focus(); }

private decimal Calculate(decimal operand1, string operator1, decimal operand2) { decimal result = 0; if (operator1 == "+") result = operand1 + operand2; else if (operator1 == "-") result = operand1 - operand2; else if (operator1 == "*") result = operand1 * operand2; else if (operator1 == "/") result = operand1 / operand2; return result; }

private void btnExit_Click(object sender, EventArgs e) { this.Close(); } } }

In this exercise, youll add exception handling to the Simple Calculator form exercise A4-E1.

1.Open the SimpleCalculator project in the Assignment5\SimpleCalculatoException directory.

2. Add a try-catch statement in the btnCalculate_Click event handler that will catch any exceptions that occur when the statements in that event handler are executed.

If an exception occurs, display a dialog box with

the error message,

the type of error,

and a stack trace.

Test the application by entering a nonnumeric value for one of the operands.

3. Add three additional catch blocks to the try-catch statement that will catch

a FormatException,

an OverflowException, and

a DivideByZeroException.

These catch blocks should display a dialog box with an appropriate error message.

4. Test the application again by entering a nonnumeric value for one of the operands. Then, enter 0 for the second operand as shown above to see what happens.

Thanks!
