将多个标签添加到面板 [英] Add multiple labels to a panel

问题描述

我如何动态地添加多个标签到一个面板谁是从一个范围创建值。我已经创建了范围，并将值添加到标签，并通过foreach循环输入到面板的标签，但问题是，我只能够输出一个。

  var range = Enumerable.Range（1，90）; 
 foreach（int i在范围内）
 {
 string num = i.ToString（）; 
 var vartable = new Dictionary< string，Label>（）; 
 vartable [num] = new Label（）; 
 vartable [num] .Text = num; 
 panel1.Controls.Add（vartable [num]）; 
 
 
 
 
 $ div class =h2_lin>解决方案

你的问题是，重新创建一个新的字典为每个迭代，我不认为是你想要的行为。将您的代码更改为：



  var range = Enumerable.Range（1，90）; 
 var vartable = new Dictionary< string，Label>（）; 
 foreach（int i在范围内）
 {
 var num = i.ToString（）; 
 var label = new Label {Text = num}; 
 vartable [num] = label; 
 panel1.Controls.Add（label）; 
} 
  




How would I dynamically add multiple labels to a panel whos values are created from a range. I have created the range and added the value to a label and inputted the label to a panel via a foreach loop but the problem is that I am only able to output one.

var range = Enumerable.Range(1, 90);
      foreach(int i in range)
      {
          string num = i.ToString();
          var vartable = new Dictionary<string, Label>();
          vartable[num] = new Label();
          vartable[num].Text = num;
          panel1.Controls.Add(vartable[num]);
      }

解决方案

Your problem is that you're creating a new dictionary for each iteration, which I don't think is your wanted behavior. Change your code to:

var range = Enumerable.Range(1, 90);
var vartable = new Dictionary<string, Label>();
foreach (int i in range)
{
    var num = i.ToString();
    var label = new Label { Text = num };
    vartable[num] = label;
    panel1.Controls.Add(label);
}
