您已经在这里

You have already asked it over here, want basic code for class library function and how to implement namespace.[^]
So, you could have wait for few time to some one respond.
If you check out the link I have provided, has step by step explanation.

Create a Class Library Project > Write a Method

Public Class MyClassLibrary
    {
      public static string MyHelloMethod()
         {
            return "Hello World";
         }

    }

生成dll.将项目添加为对调用项目的引用.

如果名称空间与其他项目不同，则添加该名称空间.

然后，

Build the dll. Add the project as reference to the calling project.

Add the namespace if its different projects.

Then,

Console.WriteLine(MyClassLibrary.MyHelloMethod())

;

这将在您的输出屏幕上打印"Hello World".

注意，我使用了静态方法，直接调用而没有创建对象.希望您知道.

;

This will print, "Hello World" in your output screen.

Note, I used the static method, to directly call with out creating object. Hope you know that.

为此，您必须编写dll 和调用程序集(exe).

尝试首先将hello world编程为例如控制台应用程序.可以的话，将一个类库项目添加到您的解决方案中，在您的控制台应用程序解决方案中对其进行引用，在dll中创建一个类，在该类中您可以将hello world代码放入方法中.

之后，在控制台应用程序中确定该类并调用该方法.运行时，使用调试器查看每一步的情况.

In order to do that you have to write the dll and the calling assembly (exe).

Try first programming the hello world for example to a console application. When that''s fine, add a class library project to your solution, reference it in your console application solution, create a class in the dll where you place the hello world code in a method.

After that istantiate the class in the console application and call the method. While running, use the debugger to see what''s happening at each step.
