静态导入c＃(static imports in c#)

静态导入c＃(static imports in c#)

C＃是否具有Java的静态导入功能？

所以代替编写代码

FileHelper.ExtractSimpleFileName(file)

我可以写

ExtractSimpleFileName(file)

编译器会知道我的意思是FileHelper的方法。

Does C# has feature like Java's static imports?

so instead of writing code like

FileHelper.ExtractSimpleFileName(file)

I could write

ExtractSimpleFileName(file)

and compiler would know that I mean method from FileHelper.

最满意答案

从C＃6.0开始，这是可能的：

using static FileHelper; // in a member ExtractSimpleFileName(file)

---

但是，以前版本的C＃没有静态导入。

您可以使用该类型的别名来获取关闭。

using FH = namespace.FileHelper; // in a member FH.ExtractSimpleFileName(file)

或者，将静态方法更改为类型的扩展方法 - 然后可以将其称为：

var value = file.ExtractSimpleFileName();

Starting with C# 6.0, this is possible:

using static FileHelper; // in a member ExtractSimpleFileName(file)

---

However, previous versions of C# do not have static imports.

You can get close with an alias for the type.

using FH = namespace.FileHelper; // in a member FH.ExtractSimpleFileName(file)

Alternatively, change the static method to an extension method on the type - you would then be able to call it as:

var value = file.ExtractSimpleFileName();
