问题描述

大家好，
如何获取在下拉列表框中选择的文件的路径?我的代码不起作用.

Hi all,
How to get the path of a file selected in the dropdownlistbox? My code does not works.

private String _WAVFile = null;
string[] files = Directory.GetFiles(@"E:\voices\", "*.wav");

        foreach (string file in files)
        {
            DropDownList1.DataSource = file;
            DropDownList1.Items.Add(new ListItem(file));
            
           
        }
// When a button is cliked
_WAVFile = Path.GetFullPath(DropDownList1.SelectedValue);
        ListBox1.Text = _WAVFile;

提前谢谢.

Thanks in advance.
