C# try/catch
C# try/catch
在 C# 编程中，异常处理由 try/catch 语句执行。 C#中的try块用于放置可能抛出异常的代码。 catch 块 用于处理异常。 catch 块前面必须有 try 块。
没有 try/catch 的 C# 示例
using System;
public class ExExample
{
public static void Main(string[] args)
{
int a = 10;
int b = 0;
int x = a/b;
Console.WriteLine("rest of the code");
}
}
输出:
Unhandled Exception: System.DivideByZeroException: Attempted to divide by zero.
