在 catch 块中返回语句

Return statements in catch blocks(在 catch 块中返回语句)

问题描述

我看到一些开发人员在 catch 块中使用 return 语句.为什么/何时这是一种有用的技术?

I have seen some developers use the return statement in a catch block. Why/when would this be a useful technique to employ?

I actually just saw the return keyword being used.

推荐答案

public void Function(){

public void Function() {

try 
{ 
    //some code here
}
catch
{ 
    return;
}

}

返回时；命中，执行流程跳出函数.这只能在 void 方法上完成.

when return; is hit, the execution flow jumps out of the function. This can only be done on void methods.

如果您不想执行其余功能，请执行此操作.例如，如果您正在执行文件 IO 并且发生读取错误，则您不想执行处理该文件中数据的代码，因为您没有它.

you do this if you dont want to execute the rest of the function. For example if you are doing file IO and a read error happens, you dont want to execute code that handles processing the data in that file since you dont have it.
