當為此 winform 啟用虛擬模式時，有一種方法可以在列表視圖中使用鼠標選擇所有項目。正在使用的工作代碼示例，我現在只能檢索一個選定的文件。在網上找不到太多示例，可以識別為重復但對我來說不是決定性的，或者答案很簡單。 private void FilesFoundList_RetrieveVirtualItem(object sender, RetrieveVirtualItemEventArgs e) { try { if (e.ItemIndex >= 0 && e.ItemIndex < ListFilesInfos.Count) { try { var acc = ListFilesInfos[e.ItemIndex]; //with colors e.Item = new ListViewItem(new string[] { acc.TagItem, acc.FileName, acc.FilePath.ToString() }) { Tag = acc, BackColor = SearchLabColor(0, Path.GetExtension(acc.FileName.ToString()), acc.FilePath.ToString(), acc.FileName.ToString()), ForeColor = SearchLabColor(1, Path.GetExtension(acc.FileName.ToString()), acc.FilePath.ToString(), acc.FileName.ToString()), UseItemStyleForSubItems = false }; // Set Tag object property to our actual AccountInfo object } catch { this.Refresh(); } } } catch { } } private void ShowItemsVirtual(List<SearchFilesInfo> infos) { try { FilesFoundList.VirtualListSize = infos.Count; // Set number of items in list view } catch { this.Refresh(); } } private void FilesFoundList_ItemSelectionChanged(object sender, ListViewItemSelectionChangedEventArgs e) { if (FilesFoundList.VirtualMode == true) { SelectedFiles.GlobalVar = (e.Item.SubItems[2]).Text.ToString() + (e.Item.SubItems[1]).Text.ToString(); } }

您可以將代碼縮寫為：
List<multiSearchSelect> multiSearchSelect = new List<multiSearchSelect>();
private void FilesFoundList_VirtualItemsSelectionRangeChanged(object sender, ListViewVirtualItemsSelectionRangeChangedEventArgs e)
{
if (FilesFoundList.VirtualMode == true)
{
multiSearchSelect=
FilesFoundList.SelectedIndices
.Select(i=> new multiSearchSelect()
{
fileName = FilesFoundList.Items[i].SubItems[1].Text,
filePath = FilesFoundList.Items[item].SubItems[2].Text
});
}
}
class multiSearchSelect
{
public string fileName { set; get; }
public string filePath { set; get; }
}

我將發布適合我目的的解決方案。我添加了 ItemsSelectionRangeChanged 事件并獲取所選文件列表。
List<multiSearchSelect> multiSearchSelect = new List<multiSearchSelect>();
private void FilesFoundList_VirtualItemsSelectionRangeChanged(object sender, ListViewVirtualItemsSelectionRangeChangedEventArgs e)
{
if (FilesFoundList.VirtualMode == true)
{
multiSearchSelect.Clear();
ListView.SelectedIndexCollection col = FilesFoundList.SelectedIndices;
if (col.Count > 1)
{
foreach (int item in col)
{
multiSearchSelect.Add(new multiSearchSelect
{
fileName = FilesFoundList.Items[item].SubItems[1].Text,
filePath = FilesFoundList.Items[item].SubItems[2].Text
});
}
}
}
}
class multiSearchSelect
{
public string fileName { set; get; }
public string filePath { set; get; }
}
