  公开 类客户
 {
  public   int  id { get ;  set ; } 
  public   string  name { get ;  set ; } 
  public   int  uid { get ;  set ; } 
} 
  public   class  loginvalidation 
 {
 connection_class c =  new  connection_class（）; 
 MySqlCommand cmd; 
 MySqlDataReader dr; 
 MySqlConnection con; 
 [WebMethod] 
 [ScriptMethod（ResponseFormat = ResponseFormat.Json）] 
  public   string  validatelogin（ string  username， string  password）
 {
 customer [] cus =  new  customer [] 
 {
  new  customer（） 
 {
 id =  101 ，
 name =   Eswar，
 uid =  3473  
} 
}; 
  return   new  JavaScriptSerializer（）。Serialize（cus）; 
} 
 
 
 
} 

我的Web服务输出：

 < ;   xml     version   =  1.0   编码  =  UTF-8 ？ >  
 <   string     xmlns   =  http://tempuri.org/ >  [{id ：101，name：Eswar，uid：3473}] <   / string  >  

任何人都可以帮助我???如何在我的C＃windows应用程序中获取此响应并打印到文本框字段

解决方案

请按照以下流程进行操作：



步骤1：添加对Windows应用程序的服务引用。



步骤2：添加引用System.Web.Extensions;



步骤3：使用System.Web.Script.Serialization添加命名空间;



步骤4：添加以下代码：

 WebService1SoapClient cc =  new  WebService1SoapClient（）; 
  string  test = cc.validatelogin（）; 
 
 customer [] deserialized =  new  JavaScriptSerializer（）。反序列化< customer [] > < /跨度>（测试）; 
 
  foreach （客户customerRec  反序列化）
 {
  int  id = customerRec.id; 
  string  name = customerRec.name; 
  int  uid = customerRec.uid; 
} 

注意：确保客户类在Windows项目中也可用，因为在进行反序列化时需要它。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.Script.Services;
using System.Web.Script.Serialization;
using MySql.Data.MySqlClient;
using System.Data;
/// <summary>
/// Summary description for loginvalidation
/// </summary>
/// 
public class customer
{
    public int id { get; set; }
    public string name { get; set; }
    public int uid { get; set; }
}
public class loginvalidation
{
    connection_class c=new connection_class();
    MySqlCommand cmd;
    MySqlDataReader dr;
    MySqlConnection con;
    [WebMethod]
    [ScriptMethod(ResponseFormat=ResponseFormat.Json)]
    public string validatelogin(string username,string password)
    {
        customer[] cus=new customer[]
        {
            new customer()
            {
                id=101,
                name="Eswar",
                uid=3473
            }
        };
        return new JavaScriptSerializer().Serialize(cus);
    }



}

My Webservice Output:

<?xml version="1.0" encoding="UTF-8"?>
<string xmlns="http://tempuri.org/">[{"id":101,"name":"Eswar","uid":3473}]</string>

Can anyone help me ??? How to get this response in my C# windows application and print into text box fields

解决方案

Please follow below process:

Step1: Add service reference to Windows App.

Step2: Add reference System.Web.Extensions;

Step3: Add namespace using System.Web.Script.Serialization;

Step4: Add below code:

WebService1SoapClient cc = new WebService1SoapClient();
            string test = cc.validatelogin();
            
customer[] deserialized = new JavaScriptSerializer().Deserialize<customer[]>(test);

foreach (customer customerRec in deserialized)
{
    int id = customerRec.id;
    string name = customerRec.name;
    int uid = customerRec.uid;
}

Note: Make sure that customer class is available in Windows project also because it is required when we do deserializeation.
