Hi,

I have a window based application developed using C#. In this application i
am using the file operation to check whether the file is available and
whether it in expected size. While doing this file operation i am getting
the following error message. Please some one help me to find the problem.

The given path's format is not supported.
Trace Message : at
System.Security.Util.StringExpressionSet.CanonicalizePath(String path,
Boolean needFullPath)
at System.Security.Util.StringExpressionSet.AddExpressions(String[] str,
Boolean checkForDuplicates, Boolean needFullPath)
at
System.Security.Permissions.FileIOPermission.AddPathList(FileIOPermissionAccess
access, String[] pathListOrig, Boolean checkForDuplicates, Boolean
needFullPath, Boolean copyPathList)
at
System.Security.Permissions.FileIOPermission..ctor(FileIOPermissionAccess
access, String[] pathList, Boolean checkForDuplicates, Boolean needFullPath)
at System.IO.FileInfo..ctor(String fileName)
at CallCenter.CommonClass.convertFile(String strFileName, Int32
intWAVFileSize, Int32 intMP3FileSize)

Thanks,
Rajagopal.S

What is this "file operation" that you are using? What is the file path
that is causing the problem? Does it contain a colon after the second
position in the path string? If so, and you're using the System.IO.File
and/or System.IO.FileInfo classes, you'll need to eliminate the colon in
order for the FileIOPermission demands used by these class methods to
function without throwing this exception.

HTH,
Nicole
