You are trying to create a FileStream object for a directory (folder). Specify a file name (e.g. @"D:\test.txt") and the error will go away.

By the way, I would suggest that you use the StreamWriter constructor that takes an Encoding as its second parameter, because otherwise you might be in for an unpleasant surprise when trying to read the saved file later (using StreamReader).

tl dr version  Make sure you are not trying to open a file marked in the file system as Read-Only in Read Write mode   I have come across this error in my travels trying to read in an XML file  I have found that in some circumstances  detailed below  this error would be generated for a file even though the path and file name are correct   File details    The path and file name are valid  the file exists Both the service account and the logged in user have Full Control permissions to the file and the full path The file is marked as Read-Only It is running on Windows Server 2008 R2 The path to the file was using local drive letters  not UNC path   When trying to read the file programmatically  the following behavior was observed while running the exact same code    When running as the logged in user  the file is read with no error When running as the service account  trying to read the file generates the Access Is Denied error with no details   In order to fix this  I had to change the method call from the default  Opening as RW  to opening the file as RO   Once I made that one change  it stopped throwing an error
