Which data you want to insert into db and also how do you know the file is being created or not?

You have to check the condition like below.

string path = @"C:\Users\Administrator\Desktop\New folder";
if (!File.Exists(path))
{
    File.Create(path);
    DateTime dt = File.GetLastWriteTime(path);
    Response.Write(string.Format("the last time {0}", dt));
}
else
{
    // Code for inserting the data to db.
}
