在 C# winform 中将所选项目从一个列表框移动到另一个列表框

Move selected items from one listbox to another in C# winform(在 C# winform 中将所选项目从一个列表框移动到另一个列表框)

问题描述

我正在尝试将列表框 1 中的选定项目移动到列表框 2，反之亦然.我有两个按钮，>> 和 <<.当我选择 listbox1 中的项目然后单击 >> 时，项目应该从 listbox1 移动到 listbox2.

I'm trying to move selected items in list box1 to list box2, and vice versa. I have two buttons, >> and <<. When I select items in listbox1 and then click on >> the items should move from listbox1 to listbox2.

private void MoveListBoxItems(ListBox source, ListBox destination)
{
    ListBox.SelectedObjectCollection sourceItems = source.SelectedItems;
    foreach (var item in sourceItems)
    {
        destination.Items.Add(item);
    }
    while (source.SelectedItems.Count > 0)
    {
        source.Items.Remove(source.SelectedItems[0]);
    }
}

private void button2_Click_1(object sender, EventArgs e)
{
    MoveListBoxItems(listbox , lstActivity);
}

推荐答案

您的代码运行良好.我测试了它.您的问题是我尝试将列表框 1 中的 选定 项移动到列表框 2."

your code works fine. i tested it. your question is "I try to move selected item in list box1 to list box2."

我认为你的 button2 有问题.删除 button2 和下面的代码

i think your button2 has problem.delete button2 and the code below

private void button2_Click_1(object sender, EventArgs e)
{
    MoveListBoxItems(listbox , lstActivity);
}

然后创建其他按钮并创建点击事件.

then create other button and create click event.

private void MoveListBoxItems(ListBox source, ListBox destination)
{
    ListBox.SelectedObjectCollection sourceItems = source.SelectedItems;
    foreach (var item in sourceItems)
    {
        destination.Items.Add(item);
    }
    while (source.SelectedItems.Count > 0)
    {
        source.Items.Remove(source.SelectedItems[0]);
    }
}

private void first2second_Click(object sender, EventArgs e)
{
    MoveListBoxItems(FirstListbox, LastListbox);
}

private void second2first_Click(object sender, EventArgs e)
{
    MoveListBoxItems(LastListbox, FirstListbox);
}

此代码有效.如果要选择多个项目更改属性SelectionMode = MultiSimple;

this code is work. if you want select more than one item change property SelectionMode = MultiSimple;
