C#随记（1）

1.新建第一个C#文件

• 点击新建文件

• 这里选择C#类常规

  

2.使用快捷键上手VS

• 这里输入svm，同时点击两下TAB键，生成主类

  

  

• Ctrl+K、Ctrl+X可以生成C#的代码段

  

• 这里选择第二个

  

  这里输入代码块

using System;

public class Class1
{
	public Class1()
	{
	}
    static void Main(string[] args)
    {
        // someWords is a string array.
        string[] someWords = {
    "the",
    "quick",
    "brown",
    "fox",
    "jumps"
    };
        string[] moreWords = {
                "over",
        "the",
        "lazy",
        "dog"
        };
        // Alphabetically sort the words.
        IEnumerable<string> query = from word in someWords
                                    orderby word
                                    select word;
    }
}

• 当我们需要注释掉某行代码时，快捷键（CTRL+K，CTRL+C）

• 同样需要注视掉某行时，快捷键(Ctrl+K, Ctrl+U)

• 当我们需要查看定义时，快捷键（Alt+F12）

  

代码补全功能

using System;

public class Class1
{
	public Class1()
	{
	}
    static void Main(string[] args)
    {
        // someWords is a string array.
        string[] someWords = {
    "the",
    "quick",
    "brown",
    "fox",
    "jumps"
    };
        string[] moreWords = {
                "over",
        "the",
        "lazy",
        "dog"
        };
        // Alphabetically sort the words.
        IEnumerable<string> query = from word in someWords
                                    orderby word
                                    select word;
        foreach (string str in query)
        {
            //CW+TAB两次
            Console.WriteLine(str);
        }
    }
}

• 代码重构：将 somewords 变量重命名为unsortedWords ，点击变量，右键重命名
