Niall Connaughton Niall Connaughton The TEMP environment variable would be set in two places: for the user itself, and for the local machine. If it's not set for the user, then the one for the local machine would be used, and that's always set in a default installation. Therefore the search usually stops on the second step.
But their example doesn't actually end with a backslash. You are not guaranteed that you will have writing permission to the path returned by that function in your application. What about if you tried IsolatedStorage instead? The correct way is to use System. GetTempPath as in the accepted answer. Helen Helen ImmortalBlue Because that's not necessarily the temp directory.
The correct way to get the temp directory is to call System. I know this is pretty old but I figured I'd leave a note for anyone curious: Not only is it not necessarily the temp directory, as DavidHeffernan said, but you simply have no clue what it is.
While not as much of an issue with. NET, it's considered poor practice because any malicious user could have altered that environment variable in order to exploit your program.
If you're running with admin privileges and the malware can alter your code as it's executing, they can, for example, execute shellcode as an admin because it's been stored in TEMP. If don't find any of those its returns path to Windows folder.
It also guarantee that it returns correct path but it's not guarantee that the path exists. But this is exactly what the accepted answer does if you don't have a TMP variable default scenario on recent Windows versions , isn't it? GetTempPath relies on your environment variables anyway, if you read the kernel documentation, so as user Logman points out there is no reason not to use GetEnvironmentVariable GetFolderPath Environment.
