C# ArgumentException类代码示例

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

本文整理汇总了C#中System.ArgumentException的典型用法代码示例。如果您正苦于以下问题:C# ArgumentException类的具体用法?C# ArgumentException怎么用?C# ArgumentException使用的例子?那么恭喜您, 这里精选的类代码示例或许可以为您提供帮助。



ArgumentException类属于System命名空间,在下文中一共展示了ArgumentException类的2个代码示例,这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞,您的评价将有助于我们的系统推荐出更棒的C#代码示例。

示例1: Main

//引入命名空间
using System;

public class Example 
{
    static void Main() 
    {
        // Define some integers for a division operation.
        int[] values = { 10, 7 };
        foreach (var value in values) {
            try {
               Console.WriteLine("{0} divided by 2 is {1}", value, DivideByTwo(value));
            }
            catch (ArgumentException e) {
               Console.WriteLine("{0}: {1}", e.GetType().Name, e.Message);
            }
            Console.WriteLine();
        }
    }

    static int DivideByTwo(int num) 
    {
        // If num is an odd number, throw an ArgumentException.
        if ((num & 1) == 1)
            throw new ArgumentException(String.Format("{0} is not an even number", num), 
                                      "num");

        // num is even, return half of its value.
        return num / 2;
    }
}
开发者ID:.NET开发者,项目名称:System,代码行数:31,代码来源:ArgumentException

输出:

10 divided by 2 is 5

ArgumentException: 7 is not an even number
Parameter name: num
