Extracting file name from the file path in C#?

Question

I've seen a couple similar questions but I can't figure out what I'm doing wrong. I have a list box where I want all selected test files to be listed without the whole path. With this current code, no text is being entered into the list box. Where am I going wrong?

if (cmdBrowse.ShowDialog() == DialogResult.OK)
{
    string testNameShort = Path.GetFileName(listboxTestsToRun.Text.ToString());
    listboxTestsToRun.Items.Add(testNameShort);
}

Thanks in advance!

Answer 1

Supposing that cmdBrowse is an OpenFileDialog and you want the filename selected by your user to be added to the listbox. In this case you code this

if (cmdBrowse.ShowDialog() == DialogResult.OK)
{
   if(cmdBrowse.FileName.Length > 0)
   {
      string testNameShort = Path.GetFileName(cmdBrowse.FileName);
      listboxTestsToRun.Items.Add(testNameShort);
   }
}

Answer 2

如果cmdBrowse是一个OpenFileDialog ，那么，除非你期望列表框中有其他有意义的东西，否则你需要使用用户选择的路径（这是我怀疑你正在尝试做的事情），例如：

var fileName = Path.GetFileName(cmdBrowse.FileName);

Answer 3

查看在开始检索的路径上执行Path.GetFileNameWithoutExtension（FilePath）方法，然后将它们添加到框中
