将项目从列表框复制到CheckedListBox [英] Copy items from ListBox to CheckedListBox

问题描述

有很多问题与这个问题相反，但是不幸的是，没有一个问题对我有用.我有以下代码可以实现我的目的:

There are many questions that ask the opposite of this question, unfortunately none of them have worked for me. I have the following code to achieve my purpose:

foreach (var item in listBox1.Items)
{
    checkedListBox1.Items.Add(item);
}

问题是当我这样做时，我没有得到 ListBox 内的值，而是 System.Data.DataRowView 项内的值.因此，我的 CheckedListBox 正是使用 System.Data.DataRowView 字符串填充的，它们都是相同的，并且不会显示实际的字符串值.

The problem is that when I do this, I don't get the values inside the ListBox, rather the System.Data.DataRowView items. So my CheckedListBox gets populated with exactly this, System.Data.DataRowView strings, which are all the same and don't show the actual string value.

编辑:我这样绑定到 ListView :我有一个 DataTable ds ，并且:

Edit: I bind to the ListView this way: I have a DataTable ds, and:

listBox1.DataSource = ds;

推荐答案

尝试一下:

foreach (var dataRowView in listBox1.Items.OfType<DataRowView>())
{
     checkedListBox1.Items.Add(dataRowView[0].ToString());
}
