我知道使用谷歌搜索我可以找到合适的答案，但我更喜欢听听您的个人(也许是技术)意见.Java 和 C# 抛出异常的差异的主要原因是什么?在 Java 中，抛出异常的方法的签名必须使用throws"关键字，而在 C# 中，您在编译时不知道是否可以抛出异常.

I know Googling I can find an appropriate answer, but I prefer listening to your personal (and maybe technical) opinions. What is the main reason of the difference between Java and C# in throwing exceptions? In Java the signature of a method that throws an exception has to use the "throws" keyword, while in C# you don't know in compilation time if an exception could be thrown.

推荐答案

因为对检查异常的响应几乎总是:

Because the response to checked exceptions is almost always:

try { // exception throwing code } catch(Exception e) { // either log.error("Error fooing bar",e); // OR throw new RuntimeException(e); }

如果你真的知道如果抛出一个特定的异常你可以做些什么，那么你可以捕获它然后处理它，否则它只是安抚编译器的咒语.

If you actually know that there is something you can do if a particular exception is thrown, then you can catch it and then handle it, but otherwise it's just incantations to appease the compiler.
