Noexcept equivilent in C#

Question

I want to ask is there in C# analogue for C++ "noexcept" attribute for methods which does not generate any exceptions. Something like that:

    public int SomeMethod() noexcept
    {
     throw new ArgumentNullException (); //Compile error: Method with 'noexcept' 
attribute can't generate exceptions.
    }

And when I want to call this method in my code I need not to think about try/catch block for this method.

据我所知，C# 中没有类似的东西（尽管我不是 100% 相信）。关于它的用途；当编写干净的代码时，您应该只在您期望异常发生的地方处理异常。这使得程序的流程和控制更加易于管理。

如果您不知道方法期间可能发生异常，或者发生您没有预料到的异常，那么您需要确定该异常是否被认为是关键的（因为它会导致应用程序失败）；或者是否应该在代码中专门处理它。
