C# finally块 C#finally块|C#教程

C＃finally块用于执行重要代码，无论是否处理异常，该代码都将执行。必须在catch或try块之前。
C＃最终示例，如果处理了异常

using System; public class ExExample { public static void Main(string[] args) { try { int a = 10; int b = 0; int x = a / b; } catch (Exception e) { Console.WriteLine(e); } finally { Console.WriteLine("Finally block is executed"); } Console.WriteLine("Rest of the code"); } }

【C# finally块】输出：

System.DivideByZeroException: Attempted to divide by zero. Finally block is executed Rest of the code

如果未处理异常，C＃最终示例

using System; public class ExExample { public static void Main(string[] args) { try { int a = 10; int b = 0; int x = a / b; } catch (NullReferenceException e) { Console.WriteLine(e); } finally { Console.WriteLine("Finally block is executed"); } Console.WriteLine("Rest of the code"); } }

输出：
