OpenFileDialog ofd = new OpenFileDialog ();

You need to create a new class, based on a TextBox, and handle the Drag-and-drop:

public class MyTextBox : TextBox
    public MyTextBox()
        AllowDrop = true;
        Multiline = true;
        DragDrop += new DragEventHandler(MyTextBox_DragDrop);
        DragEnter += new DragEventHandler(MyTextBox_DragEnter);

    void MyTextBox_DragEnter(object sender, DragEventArgs e)
        e.Effect = DragDropEffects.Copy;

    void MyTextBox_DragDrop(object sender, DragEventArgs e)
        DataObject data = (DataObject)e.Data;
        if (data.ContainsFileDropList())
            string[] rawFiles = (string[])e.Data.GetData(DataFormats.FileDrop);
            if (rawFiles != null)
                List<string> lines = new List<string>();
                foreach (string path in rawFiles)
                Lines = lines.ToArray();

Oops! Went a little far there...That displays the file content, rather than path. Path is even easier: just replace
