{	"children" : [{			"children" : [{					"children" : [],					"name" : "b"				}			],			"name" : "aaa"		}, {			"children" : [{					"children" : [],					"name" : "t22Name"				}, {					"children" : [],					"name" : "b"				}			],			"name" : "t2"		}	],	"name" : "a"}

上面的JSON要使用C#生成，自己拼字符串很麻烦，需要一个嵌套类，类很简单：

class nestedClass    {        public string name { get; set; }        public List
    
      children = new List
     
      ();    }
     
    

使用示例：

nestedClass t = new nestedClass();t.name = "a";nestedClass t1 = new nestedClass();t1.name = "aaa";nestedClass t11 = new nestedClass();t11.name = "b";t1.children.Add(t11);t.children.Add(t1);nestedClass t2 = new nestedClass();t2.name = "t2";t.children.Add(t2);nestedClass t22 = new nestedClass();t22.name = "t22Name";t2.children.Add(t22);t2.children.Add(t11);JSONHelper.WriteJSON(t);
