C# ListBox数据互换_c# listbox选项对调-优快云博客

本文介绍了一种在C#中实现两个ListBox间数据互相转移的方法。通过按钮点击事件触发，选择ListBox1中的项并移至ListBox2，再从ListBox2选中项返回ListBox1，实现了双向的数据交换。

C#中两个ListBox数据互换的逻辑，下面为一段实例code，供参考。

private void btn2Right_Click(object sender, System.EventArgs e)
  {

   //Add item from ListBox1
   for (int i = 0; i < this.ListBox1.Items.Count ; i++)
   {
    if(ListBox1.Items[i].Selected)
    {
     this.ListBox2.Items.Add(new ListItem(ListBox1.Items[i].Text,ListBox1.Items[i].Value));
    }
   }

   //Delete item from ListBox1, when it add item to ListBox2 successful
   for (int i = this.ListBox1.Items.Count -1; i >=0 ; i--)
   {
    if(ListBox1.Items[i].Selected)
    {
     this.ListBox1.Items.Remove(ListBox1.Items[i]);
    }
   }
  }

  private void btn2Left_Click(object sender, System.EventArgs e)
  {
   //Add item from ListBox2
   for (int i = 0; i < this.ListBox2.Items.Count ; i++)
   {
    if(ListBox2.Items[i].Selected)
    {
     this.ListBox1.Items.Add(new ListItem(ListBox2.Items[i].Text,ListBox2.Items[i].Value));
    }
   }
   //Delete item from ListBox2, when it add item to ListBox1 successful
   for (int i = this.ListBox2.Items.Count -1; i >=0 ; i--)
   {
    if(ListBox2.Items[i].Selected)
    {
     this.ListBox2.Items.Remove(ListBox2.Items[i]);
    }
   }
  }
