本文整理汇总了C#中System.ArgumentException类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, 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;
}
}输出：
10 divided by 2 is 5 ArgumentException: 7 is not an even number Parameter name: num
