如何QUOT&;进出口QUOT; C＃中的静态类？ [英] How to "import" a static class in C#?

问题描述

我创建了一个公共静态类utils.cs我想在其他班级使用它不与utils的前缀的方法，什么是做到这一点的语法​​？

I have created a public static class utils.cs I want to use it in other classes without prefixing method with utils, what's the syntax to do this ?

推荐答案

什么乔恩斯基特是不会告诉你的是，你的可以的在C＃中全局静态成员。你的实用类的确可以成为C＃中的现实。

What Jon Skeet is not telling you is that you can have global static members in c#. Your utility class can indeed become a reality in c#.

不幸的是，微软已确定建设这些成员如上单纯的正常的发展过程本身，并要求您的原中间语言的伪造他们。 。如此强大的模式是上述常见的语法高亮和友好的图标）

Unfortunately, Microsoft has determined that the very process of constructing such members as above mere "normal" development, and requires that you forge them from raw intermediate language. Such a powerful pattern is above common syntax highlighting and friendly icons).

下面是UTF-8字符（小心戒备吧）的所需序列：

Here is the requisite sequence of utf-8 characters (guard it carefully):

.assembly globalmethods {}

.method static public void MyUtilMethod() il managed 
{
  ldstr "Behold, a global method!"
  call void [mscorlib]System.Console::WriteLine(class System.String) 
  ret
}

（您可以通过在SDK命令提示符下调用编译ilasm.exe这个例子中，记住使用/ DLL开关）

(You could compile this example by invoking ilasm.exe from the SDK command prompt, remembering to use the /dll switch)

ilasm.exe输出：

一旦你编译新创建的组件（如globalmethods.dll为例），它只是一个添加在Visual Studio中引用的问题。该操作完成时，你最好是坐下来，因为这将是一次写一些实际的代码：

Once you have compiled your newly created assembly (as "globalmethods.dll" for example), it's just a matter of adding a reference in Visual Studio. When that is complete, you better be sitting down, because it will be time to write some real code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Reflection;

namespace TestGlobalMethod
{
    class Program
    {
        static void Main(string[] args)
        {

            "MyUtilMethod".Call();

            Console.ReadKey();

        }

    }

    /// <summary>
    /// Reduces the amount of code for global call
    /// </summary>
    public static class GlobalExtensionMethods 
    {
        public static void Call(this string GlobalMethodName)
        {
            Assembly.Load("globalmethods")
                .GetLoadedModules()[0].GetMethod(GlobalMethodName)
                    .Invoke(null,null);

        }

    }


}

是的，你刚才叫C＃中的全局方法。

Yes, you just called a Global method in c#.

*请不要使用此，它例如仅​​:-)此外，你很可能写在另一种语言全局方法支持他们，如VB。 NET。

*Please don't use this, it's for example only :-) Also, you could probably write your global methods in another language that support them, such as VB.NET.
