在Windows中运行相对路径？

Question

我正在尝试从VB.NET应用程序中运行目标相对路径。我确保使用反斜杠（而不是正斜杠），并运行Process，将工作目录设置为正确的源路径;尝试运行时仍然出现The system cannot find the file specified错误。

例如，我有（伪代码）：

txtSource.text path = "C:\Windows\System32"

txtResult.text path = "..\notepad.exe"

到目前为止，这是Sub：

Private Sub btnTest_Click(sender As Object, e As EventArgs) Handles btnTest.Click

    Try

        ' Create the process object
        Dim pRun As New Process()

        ' Set it to run from the Source folder (Working Directory)
        With pRun.StartInfo
            .UseShellExecute = False
            .WorkingDirectory = IO.Path.GetDirectoryName(txtSource.Text.Trim)
            .FileName = txtResult.Text.Trim
        End With

        pRun.Start()

        ' Wait for it to finish
        pRun.WaitForExit()

    Catch ex As Exception

        Debug.Print(ex.Message)

    End Try

End Sub
