我在工作室代码中使用 C#，如何从列表视图中的选中列中获取内容？

Question

I'm using C# in studio code, now I created a form with listview, I added columns and checkboxes in the listview, and I want to ask how to extract the content of the first column from the checked row.

I tried to search for ways online but none of them work I guess..

Answer 1

To be able to extract data you can try the following:

• First, you need to get a reference to the listview control. You can do this by using the FindControl method or by using the ID property of the listview.

• Next, you can use the CheckedItems property of the listview to get a collection of all the checked rows.

• You can then use a foreach loop to iterate through each checked row
  in the collection.

• For each checked row, you can use the SubItems property of the
  ListViewItem to get a collection of all the subitems (columns) in the row.

  You can then use the Text property of the first subitem (column) in the collection to get the content of the first column.

Short example:

foreach (ListViewItem item in listview1.CheckedItems)
{
    string firstColumnText = item.SubItems[0].Text;
    // Do something with the firstColumnText value here
}
