我学习C＃和陷入一片code，我不明白。我希望你能clearify对我来说。

I'm studying C# and caught a piece of code that I don't understand. I was hoping that you could clearify it for me.

CreateCustomerTask.<>c__DisplayClass0 cDisplayClass0 =
         new CreateCustomerTask.<>c__DisplayClass0();

什么的＆LT;＆GT; 意味着什么？为什么有一个。（点）在它的前面？

What does the <> signify? And why is there a . (dot) in front of it?

推荐答案

您正在寻找一些反编译code - 确切地说，是由编译器生成的东西

You're looking at some decompiled code - specifically, something that was generated by the compiler.

编译器使用＆LT;＆GT; （这是一个实现细节），因为，虽然它是有效的CLR标识符做起了这样的文字，它不是在C＃有效 - 所以它保证该名称不会在C＃code任何名称冲突

The compiler uses <> (this is an implementation detail) because, whilst it's valid for a CLR identifier to start with such characters, it's not valid in C# - so it's guaranteed that the name will not conflict with any names in the C# code.

为什么的编译器生成此code变化 - 它可以是实施拉姆达的，或迭代器或异步块，可能还有一些其他的原因，也

why the compiler has generated this code varies - it can be the implementation of a lambda, or an iterator or async block, and possibly some other reasons also.

和，希望你的问题的另一部分还回答了 - 有一个 在它前面的通常的原因 - 以独立的名称空间的部分，或更可能在这种情况下，从封闭类名称的嵌套类的名称区分开来。

And, hopefully the other part of your question is also answered - there's a . in front of it for the usual reasons - to separate namespace portions, or more likely in this case, to separate the name of a nested class from the name of the enclosing class.
