一、代表当前实例对象
1 #region 代表当前实例对象 2 public string Name = "全局变量"; 3 public void GetResult() 4 { 5 this.Name = "局部变量"; 6 Console.WriteLine(this.Name); 7 } 8 #endregion
二、用this串联构造函数
1 #region 用this串联构造函数 2 public ThisKey() 3 { 4 Console.WriteLine("无参数构造函数"); 5 } 6 7 public ThisKey(string name) : this() 8 { 9 Console.WriteLine(name); 10 Console.WriteLine("有参数构造函数"); 11 } 12 13 public ThisKey(string text, int number) : this(text) 14 { 15 16 } 17 #endregion
三、扩展方法
1 #region 扩展方法 2 public int Count<T>(this IEnumerable<T> Source) 3 { 4 return Source.Count(); 5 } 6 7 #endregion 8 9 var sources = new List<People> 10 { 11 new People() 12 { 13 ID=1, 14 Name="2" 15 }, 16 new People() 17 { 18 ID=1, 19 Name="2" 20 } 21 }; 22 var count = thisKey.Count<People>(sources); 23 Console.WriteLine(count);
