i试试这个



我有什么试过：

i try to get time of file. scanerio is when any last file is saved in folder i want that file date time in console

What I have tried:

public static void Main()
        {

            {
                string path = @"C:\Users\Administrator\Desktop\New folder\DB.txt";
                if(!File.Exists(path))
                {
                    File.Create(path);
                }
                else
                {
                    File.SetLastWriteTime(path, new DateTime());
                }
                DateTime dt = File.GetLastWriteTime(path);
                Console.WriteLine("the last time {0}", dt);
                Console.ReadLine();
            }
            catch (Exception e)
            {
                Console.WriteLine("The process failed: {0}", e.ToString());
            }

        }

但这显示错误

Not一个有效的Win32 FileTime。

任何解决方案

but this shows error
Not a valid Win32 FileTime.
any solution

推荐答案

你想通过以下代码行实现什么？

What you want to achieve through following line of code?

File.SetLastWriteTime(path, new DateTime());

如果要将当前日期时间设置为LastWriteTime，请尝试以下操作 -

If you want to set current datetime as LastWriteTime, try following-

File.SetLastWriteTime(path, DateTime.Now);

如果您仍然遇到相同的错误或者您的要求是其他原因，请告诉我。

If you still experience the same error or if your requirement is something else, please let me know.
