Vs2010重构工具针对C#提供以下方式：

1. 重命名

2. 将方法中的代码提取成新的方法。默认情况是private statid void

3. 将私有变量提取为属性

4. 提取接口

5. 删除方法中的参数

6. 修改方法中的参数，参数顺序

Rename

快捷键：Ctrl+R,R

namespace CSharpTest

{
     class Test1
     {
         public void TT()
         {
             Console.WriteLine("Hello");
         }
  
     }
     class Program
     {
         static void Main(string[] args)
         {
             Test1 t = new Test1();
  
             t.TT();
         }
     }

}

Extract Method

快捷键：Ctrl+R,M

class Test1
     {
         public void TT()
         {
             Console.WriteLine("Hello");
         }
  
     }
     class Program
     {
         static void Main(string[] args)
         {
             Test1 t = new Test1();
  
             t.TT();
         }
     }

 class Test1
     {
         public void TT()
         {
             PrintHello();
         }
  
         private static void PrintHello()
         {
             Console.WriteLine("Hello");
         }
  
     }
     class Program
     {
         static void Main(string[] args)
         {
             Test1 t = new Test1();
  
             t.TT();
         }
     }

Encapsulate Field

快捷键：Ctrl+R,E

       private string name;

        public string Name
         {
             get { return name; }
             set { name = value; }
         }

Extract Interface

快捷键：Ctrl+R,I

提取接口，必须选定一个函数进行多态

Remove Parameters

快捷键：Ctrl+R,V

        public void Test1(int id,int number,int score)
         {
             Console.WriteLine(id);
             Console.WriteLine(number);
             Console.WriteLine(score);
         }

       t.Test1(1, 1000, 90);

删除number

        public void Test1(int id, int score)
         {
             Console.WriteLine(id);
             
             Console.WriteLine(score);
         }

       t.Test1(1, 90);

Reorder Parameters

快捷键：Ctrl+R,O

       public void Test1(int id,int number,int score)
         {
             Console.WriteLine(id);
             Console.WriteLine(number);
             Console.WriteLine(score);
         }

       t.Test1(1, 1000, 90);

把number和score调换位置

        public void Test1(int id, int score, int number)
         {
             Console.WriteLine(id);
             Console.WriteLine(number);
             Console.WriteLine(score);
         }

       t.Test1(1, 90, 1000);
