练习 - 完成质询活动以捕获特定异常

已完成

本模块中的代码挑战用于强化你学到的知识，并在继续作之前帮助你获得一些信心。

捕获特定异常质询

在此挑战中，你得到了一个代码示例，该代码示例生成了几种不同的异常类型。 单个 try 代码块包含生成异常的代码。 包含多个 catch 子句来处理特定异常类型。

需要更新代码示例，以便捕获每个异常，并向控制台显示相应的错误消息。

下面是此挑战的要求：

1. 确保Program.cs文件包含以下代码示例：

   try
   {
       int num1 = int.MaxValue;
       int num2 = int.MaxValue;
       int result = num1 + num2;
       Console.WriteLine("Result: " + result);
   
       string str = null;
       int length = str.Length;
       Console.WriteLine("String Length: " + length);
   
       int[] numbers = new int[5];
       numbers[5] = 10;
       Console.WriteLine("Number at index 5: " + numbers[5]);
   
       int num3 = 10;
       int num4 = 0;
       int result2 = num3 / num4;
       Console.WriteLine("Result: " + result2);
   }
   catch (OverflowException ex)
   {
       Console.WriteLine("Error: The number is too large to be represented as an integer." + ex.Message);
   }
   catch (NullReferenceException ex)
   {
       Console.WriteLine("Error: The reference is null." + ex.Message);
   }
   catch (IndexOutOfRangeException ex)
   {
       Console.WriteLine("Error: Index out of range." + ex.Message);
   }
   catch (DivideByZeroException ex)
   {
       Console.WriteLine("Error: Cannot divide by zero." + ex.Message);
   }
   
   Console.WriteLine("Exiting program.");
   

2. 更新代码，以便在发生异常类型时向控制台显示每个错误消息。

3. 验证更新的代码是否将以下消息输出到控制台：

   Error: The number is too large to be represented as an integer. Arithmetic operation resulted in an overflow.
   Error: The reference is null. Object reference not set to an instance of an object.
   Error: Index out of range. Index was outside the bounds of the array.
   Error: Cannot divide by zero. Attempted to divide by zero.
   Exiting program.
   

祝你好运！
