Question

我正在尝试将列表框1中的所选项目移到列表框2，反之亦然。我有两个按钮>>和<<。当我在listbox1中选择项目然后点击>>时，项目应该从listbox1移动到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);
}

Answer 1

您的代码运行正常。我测试了它。您的问题是“我尝试将列表框1中的选定项目移至列表框2。”

我认为你的button2有问题。删除按钮2和下面的代码

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。

完整来源：

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);
}

这段代码很有用。如果要选择多个项目更改属性 SelectionMode = MultiSimple;

Answer 2

private void buttonMoveToListBox1_Click(object sender, EventArgs e)
{
    if(listBox1.SelectedIndex != -1)
    {
        listBox2.Items.Add(listBox1.SelectedValue);
        listBox1.Items.Remove(listBox1.SelectedValue);
    }
}

private void buttonMoveToListBox2_Click(object sender, EventArgs e)
{
    if(listBox2.SelectedIndex != -1)
    {
        listBox1.Items.Add(listBox2.SelectedValue);
        listBox2.Items.Remove(listBox2.SelectedValue);
    }
}

Answer 3

每个已删除的行都会有冲突，因此请使用以下代码：

<强>＆GT;＆GT;

     for (int intCount = ListBox1.SelectedItems.Count - 1; intCount >= 0; intCount--) 
     {
        ListBox2.Items.Add(ListBox1.SelectedItems[intCount]);
        ListBox1.Items.Remove(ListBox1.SelectedItems[intCount]);
     }

<强>＆LT;＆LT;

     for (int intCount = ListBox2.SelectedItems.Count - 1; intCount >= 0; intCount--)
     {
        ListBox1.Items.Add(ListBox2.SelectedItems[intCount]);
        ListBox2.Items.Remove(ListBox2.SelectedItems[intCount]);
     }

如果上述方法不起作用，请尝试以下方法：

while (ListBox1.SelectedItems.Count > 0) 
{ 
    ListBox2.Items.Add(ListBox1.SelectedItems[0].Text);  
    ListBox1.SelectedItems[0].Remove(); 
}

获取＆gt;＆gt;和＆lt;＆lt;用listbox2和3下面的2个列表框创建的按钮...首先通过get-content或get-adcomputer等获取列表框2中的项目。

$buttonMOVERight_Click={
    foreach ($Srv in $listbox2.selectedItems)
        {$selectedServers=$Srv}
    $listbox3.BeginUpdate()
    foreach($TSrv in $Srv)
        {$listbox3.Items.Add($TSrv);
        $listbox2.Items.Remove($TSrv);}                         
    $listbox3.EndUpdate()
}

$buttonMoveLeft_Click={
        #TODO: Place custom script here
        foreach ($Srvs in $listbox3.selectedItems)
        {$ServersinRt=$Srvs}
    $listbox2.BeginUpdate()
    foreach($rSRv in $Srvs)
        {$listbox2.Items.Add($rSRv);
        $listbox3.Items.Remove($Srvs);}
        $listbox2.EndUpdate()
}
