c# - How to set long string(>260) in default FileName in SaveFileDialog? -

I am using a SaveFileDialog and I have to set long string (longFileName) in FileName. The string longFileName is known in runtime.

If I set

  saveFileDialog.FileName = longFileName;  

Then I get the system.IO.PathTooLongException .

How can I do this? The bottom line is ... You can not do, the maximum file name for NTFS is 256.

My advice, minimize your filename.
