The Length shows zero, because the length is zero. See MSDN: SaveFileDialog.OpenFile method[^]

"this method creates a new file with the selected name and opens it with read/write permissions. This can cause unintentional loss of data if you select an existing file to save to. To save data to an existing file while retaining existing data, use the File class to open the file using the file name returned in the FileName property."
