我有一个json Url，但我有更多的Forenames。现在它只显示一个Forename。



公共类详情

{



public string id {get;组; }

公共字符串名称{get;组; } $ / $
public int lID {get;组; }

public string uuid {get;组; }

public string wpUID {get;组; }

public string fname {get;组; }



}

private void Form2_Load（object sender，EventArgs e）{



var json1 = new WebClient（）。DownloadString（http://dev.ibeaconlivinglab.com:1881/showemployeesbyhu

urders？id =+ companyID）;





列表< details> detailsList = JsonConvert.DeserializeObject< list>< details>>（json1）;



foreach（详情详见dets1）

{



label3.Text = dets1.fname;

this.Controls.Add（label3）;

< br $>
}

}



Json：



[{id：1，fname：Jeff，}，{id：1，fname：Jan，}，{id：1，fname：Piet ，}]



我的尝试：



foreach（详情dets1 in detailsList）

{



var label = new Label（）;

label.Name = dets1 .fname;

label.Text = dets1.fname;



this.Controls.Add（label）;

}

解决方案

当您添加标签时，它们只会相互叠加，因此您只能看到一个。您需要确保添加标签以使它们不重叠

  int  x =  10 ; 
  int  y =  10 ; 
 
  foreach （详情dets1  in  detailsList）
 {
  var  label =  new  Label（）; 
 label.AutoSize =  true ; 
 label.Location =  new  Point（x，y）; 
 label.Name = dets1.fname; 
 label.Text = dets1.fname; 
 
  this  .Controls.Add（label）; 
 
 y + = label.Height +  5 ; 
} 

或者更好的是将它们添加到更合适的控件中。

尝试使用 Json.NET - Newtonsoft [ ^ ]



创建一个属性与json字符串匹配的类

< pre lang =C＃> class MyType
{
public 字符串 id { get ; set ; }
public string fname { get ; set ; }
}

并使用Deserialise方法可以将其转换为类型列表

 < span class =code-keyword> string  jsondata =   [{\id\ ：1，\fname \：\Jeff \，}，{\id \：1，\fname \：\Jan \，}， {\id \：1，\fname \：\Piet \，}]; 
  var  items = JsonConvert.DeserializeObject< List< MyType>>（jsondata）; 
  foreach （ var  item  in 项目）
 {
  string  id = item.id; 
  string  name = item.fname; 
}

I got a json Url but I've got more Forenames in it. Right now it only shows one Forename.

public class details
{

public string id { get; set; }
public string name { get; set; }
public int lID { get; set; }
public string uuid { get; set; }
public string wpUID { get; set; }
public string fname { get; set; }

}
private void Form2_Load(object sender, EventArgs e){

var json1 = new WebClient().DownloadString("http://dev.ibeaconlivinglab.com:1881/showemployeesbyhu
urders?id=" + companyID);


List<details> detailsList = JsonConvert.DeserializeObject<list><details>>(json1);

foreach (details dets1 in detailsList)
{

label3.Text = dets1.fname;
this.Controls.Add(label3);

}
}

Json :

[ { "id": 1, "fname": "Jeff", }, { "id": 1, "fname": "Jan", }, { "id": 1, "fname": "Piet", } ]

What I have tried:

foreach (details dets1 in detailsList)
{

var label = new Label();
label.Name = dets1.fname;
label.Text = dets1.fname;

this.Controls.Add(label);
}

解决方案

When you add the labels they just get added on top of each other so you only see the one. You need to make sure the labels are added such that they don't overlap

int x = 10;
int y = 10;

foreach (details dets1 in detailsList)
{
    var label = new Label();
    label.AutoSize = true;
    label.Location = new Point(x, y);
    label.Name = dets1.fname;
    label.Text = dets1.fname;

    this.Controls.Add(label);

    y += label.Height + 5;
} 

Or better yet add them to a more appropriate control.

try this using Json.NET - Newtonsoft[^]

Create a class with properties matching your json string

class MyType
       {
           public string id { get; set; }
           public string fname { get; set; }
       }

and using Deserialise method can convert it to its list of Type

string jsondata = "[{\"id\": 1,\"fname\": \"Jeff\",},{\"id\": 1,\"fname\": \"Jan\",},{\"id\": 1,\"fname\": \"Piet\",}]";
var items = JsonConvert.DeserializeObject<List<MyType>>(jsondata);
foreach (var item in items)
{
    string id = item.id;
    string name = item.fname;
}
