How To Delete Temp File On Any Win CPU

Question

Today I'm wondering if I could delete a TEMP file. I have the coding to delete the correct path name but it wont work on any other win pc due to only allowing me to using my folder naming on pc.

This is because when I play a mp3 though resources in winforms it wont let me play another song till TEMP file from previous play is deleted.

I'm looking for all files delete to save me from selecting a path name where I prefer to delete all files in the TEMP as I want to share my tool with others.

Heres the coding I'm using

if (System.IO.File.Exists(@"C:\Users\g\AppData\Local\Temp"))
{
    System.IO.File.Delete(@"C:\Users\g\AppData\Local\Temp");

    MessageBox.Show("TEMP File Deleted");
}
else
{
      MessageBox.Show("Not Done");
}

Also, it's unlikely that on every other systems the user is also named "g". — MSalters, Jan 04 '17 at 07:53
@AnthonyRaven Don't try to be smart. If you check if a *file* exists and it is in fact a *directory*, it will return false. Your code does work if you change `File` to `Directory`. You could also just truncate `%temp%`, which is shorthand for the temp directory. — Patrick Hofman, Jan 04 '17 at 08:17

You can use Path.GetTempPath() to get the path of the temporary folder, But There may be some files in the temp location are used by another processes, so you should care about the IOExceptions while deleting those files/folders,

// for deleting sub directories in temp
foreach (string subDirectory in Directory.GetDirectories(Path.GetTempPath()))
{
    try
    {
        Directory.Delete(subDirectory, true); 
    }
    catch
    {                       
    }
}
// for deleting files in temp

foreach (string tempfile in Directory.GetFiles(Path.GetTempPath(),"*.*",SearchOption.TopDirectoryOnly))
 {
     try
     {
         System.IO.File.Delete(tempfile);
     }
     catch
     {
     }
 }

It will clear all the temp or dump files from your system.
