推荐答案

如果您要做的只是从ListView中的第二列获取值，并将其写入RichTextBox：

If all you want to do is get the value from the second column in the ListView, and write it to the RichTextBox:

private string space = " ";
private string newLineString = Environment.NewLine;

private void WriteLvToRtfBox_Click(object sender, EventArgs e)
{
    foreach (ListViewItem lvItem in listView1.Items)
    {
        richTextBox1.Text +=                       
            lvItem.SubItems[1]
            .Text
            .Replace(newLineString, String.Empty)
            .Replace(space, String.Empty)
            + newLineString; 
    }
}
