Second, create a "Hello World" program with VS2013

　　1. Click "File" in the top left corner, then "new" and click "Project" .

　　

　　2. Select "Visual C #", then click "Console Application", then click OK in the bottom right corner. What does it mean to draw the red line?

　　name : Refers to the name of the project.

　　location : means where to put the production code (do not have the Chinese path)

　　Solution Name : The place where a project is stored, that is, there can be several different projects within the solution.

　　3, according to the code in the figure to knock once again, do not care what meaning, after the knock on the key combination of "ctrl+s" to save the code, and then press the key combination "CTRL+F5" quickly run this code, and then will pop up a console window, and the data inside the window is just "Hello world!",:

The console displays "Hello world!":

Third, analyze the code just now

Let's take a look at what the code is made of, as shown in the following sections:

　　reference Namespaces : Similar to a guide package in Java. For example, suppose I create a Class B, and now I want to call a "eat" method in Class B, just to have a "eat" method in Class A, so I call this method in Class B.       (For the sake of understanding, regardless of the static problem), how to call the Class A method in class B? "A.　　Eat ", and every time you call to eat the way you want to " A. "  eat ", this is too troublesome. And if I write the using a directly above the code, then I do not need "a" in B to eat, but directly "eat" on the line, thus eliminating the "a." This step, and every time you can directly call "eat" on the line.

　　Project Name: The name of the project, in which multiple classes can be contained within a project.

　　class Name: The name of the class.

　　Main Method : The main method is the entrance to the program, which means that the execution code starts here from main.

　　

Now let's see what the two lines of code mean:

Console.WriteLine ("Hello world!") This means: show the word in parentheses in the console window, that is, Hello world!

console.readline () This means: When the program runs to this sentence, pausing the console and then pressing any key will close the console window. If this sentence is not added, the console window displays "Hello world!" After a flash, that is, immediately close, basically is not clear what is displayed.
