File.Delete Access to the path is denied

Question

My console application program is creating some runtime files while it is working so what I want to do is delete all of these files on the application startup. I have tried

You say that the files are not open in another application, but it must be open within your application:

//Create some directories to delete
Directory.CreateDirectory("C:/Temp/DeleteMe");
Directory.CreateDirectory("C:/Temp/DeleteMe/DeleteMe");
File.Create("C:/Temp/DeleteMe/DeleteMeFile");//FileStream still open!!

//Delete the files
var directory = new DirectoryInfo("C:/Temp/DeleteMe");
if (!directory.Exists) return;
foreach (FileInfo file in directory.GetFiles())
{
    file.Delete();
}
foreach (DirectoryInfo dir in directory.GetDirectories())
{
    dir.Delete(true);
}

Make sure you dispose the file stream when you create the file

//Create some directories to delete
Directory.CreateDirectory("C:/Temp/DeleteMe");
Directory.CreateDirectory("C:/Temp/DeleteMe/DeleteMe");
using (File.Create("C:/Temp/DeleteMe/DeleteMeFile")) { }

//Delete the files
var directory = new DirectoryInfo("C:/Temp/DeleteMe");
if (!directory.Exists) return;
foreach (FileInfo file in directory.GetFiles())
{
    file.Delete();
}
foreach (DirectoryInfo dir in directory.GetDirectories())
{
    dir.Delete(true);
}
