I have c# application. This write log in folder.
below code.
if (File.Exists(@"C:EXT_LOGLOG.txt"))
{
File.Delete(@"C:EXT_LOGLOG.txt");
}
string Data = "xxxxx";
System.IO.StreamWriter file = new StreamWriter(@"C:EXT_LOGLOG.txt");
file.WriteLine(Data);
file.Dispose();
file.Close();
I delete file, if it exist, and I create file with same name.
when I run program, the creation date of file is not change.
I guess windows any manager or any file table still contain that file.
So, when I delete file, can I delete manager or file table content??

How and when are you retrieving the creation date? If it's just Windows Explorer, have you tried hitting F5 to refresh the view?

@GrantWinney Actually you can test this yourself from Windows Explorer. 1) Find an existing old file. 2) delete it 3) Create a new file with the same name 4) New file will have the same Created as per old file (assuming you do it sufficient quickly). See dotnetkid's answer below. I was surprised myself :)

The reason for this is to enable safe save. Like what MS WORD does. When application programs auto save, they do not over-write files. Instead, they move old file, and create a replica new file. However, the new file needs to retain the attributes of old file including creation time. Refer to temp files you see with ~ sign before them, enabling hidden files to see this happening.

That's how it works in windows. I have not searched Google for WHY. However it seems you can set the creation date of the file through C# using System.IO.File.SetCreationTime method.
public static void SetCreationTime(
string path,
DateTime creationTime
)

As dotnetkid mentioned, this is the default windows behaviour. The reason for this behaviour can be found here: support.microsoft.com/en-us/kb/172190

this is how I solve the problem:
File.WriteAllBytes(outFile, body);
File.SetCreationTimeUtc(outFile, DateTime.UtcNow);
