SPFile.OpenBinaryStream method

Opens the file as a stream.

Namespace:  Microsoft.SharePoint
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

public Stream OpenBinaryStream()

Return value

Type: System.IO.Stream
An object that represents the file.

Under specific circumstances, an error can occur that prompts the following message "The path specified is being used in a substitute" (HRESULT: 0x80070092). This error occurs when you create an instance of SPFile by using the SPWeb.GetFile(Guid) method, passing in the GUID of the desired file. If you then call the OpenBinaryStream method, the parameter reference is incorrectly a null reference (Nothing in Visual Basic) and causes the error described.

To work around this problem, use the GetFile(String) version of the GetFile method and instead of a GUID, pass in the URL to the file.
