在构造函数中尝试/ catch块 [英] Try/catch blocks inside constructors

问题描述

在构造函数中有try / catch块是一个糟糕的编程习惯吗？或者它没有什么区别只要我们的程序处理typeinitializer异常优雅。

Is it a bad programming practice to have try/catch blocks inside constructors? Or does it make no difference as long as our programs handle typeinitializer exceptions gracefully.

在C＃中，如果构造函数中存在任何异常，框架总是抛出类型异常。

In C# if there are any exceptions inside a constructor the framework always throws typeinitilizer exceptions.

推荐答案

System.TypeInitializationException em> static 构造函数抛出异常，而不是实例构造函数。

System.TypeInitializationException is thrown when a static constructor throws an exception, not on an instance constructor. Exceptions are thrown normally in instance constructors.

除此之外，没有什么错误，它比任何其他地方都多;处理可以从中正确恢复的异常，并允许那些不能冒泡的异常。

That aside, there's nothing "wrong" with it any more than it is anywhere else; handle exceptions that you can properly recover from, and allow those that you can't to bubble up.
