// 定义 实体测试类
public class Customer

public Customer()   // 貌似空构造函数必须

string jsonStr = JavaScriptConvert.SerializeObject(cusList);  //序列化成 Json 格式
txt_RtnJson.Text = jsonStr;

List<Customer> cusList2 = JavaScriptConvert.DeserializeObject<List<Customer>>(txt_fetchXml.Text); // 将 Json 字符串.反序列化成 实体类对象集
