推荐答案

在您的应用程序运行时，您可以将其锁定为:

When your application is running you can lock it as :

using (FileStream fs =
         File.Open("MyFilepath", FileMode.Open, FileAccess.Read, FileShare.None))
{
   // use fs
}

如果您希望在应用程序未运行时也拥有永久锁，请执行以下操作:

您可能会想到带有以上代码的Windows服务.

If you would like to have a permanent lock even when your application is not running :

You may think of Windows Service with the above code.
