在 C# 编程中,异常处理是通过 try/catch 语句执行的。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 块必须在 try 块之前。
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:
未处理的异常:System.DivideByZeroException:试图除以零。
using System;

try
{

int b = 0;
int x = a / b;
}
catch (Exception e) { Console.WriteLine(e); }
Console.WriteLine("Rest of the code");
}
}输出:
