c# - 获取 CodeDomProvider 实例的正确方法

Question

var codeProvider = new CSharpCodeProvider();

or 

var codeProvider = new CodeDomProvider.CreateProvider("C#");

他们似乎在做同样的事情，这让我很困惑!

Answer 1

var codeProvider = new CSharpCodeProvider(); 其中 CSharp 是运行时之前的已知语言。

请参阅下面关于 CodeDomProvider.CreateProvider 的注释方法引用:

This method is most commonly used to create an instance of a code provider in an application that may optionally use one of several providers. CreateProvider allows you to specify at run time the code provider you wish to instantiate. If you know at design time which code provider is to be used, you should create an instance of that code provider rather than use the CreateProvider method.
