C#编程解决Windows定时关闭共享文件访问会话

在C#中,为了定时关闭共享文件访问会话,你可以使用`System.Threading.Timer`类或者`Task.Delay`结合`FileStream`的`Close()`方法。下面是一个使用`Timer`的例子,每隔一段时间关闭文件流:
```csharp
using System;
using System.IO;
using System.Threading;
class Program
{
private Timer fileStreamClosingTimer;
public void StartClosingSession()
{
// 创建一个文件流
using (FileStream fileStream = new FileStream("file.txt", FileMode.Open, FileAccess.ReadWrite, FileShare.Read))
{
fileStreamClosingTimer = new Timer(CloseFileStream, null, TimeSpan.FromSeconds(5), TimeSpan.FromSeconds(5)); // 每隔5秒执行一次
}
}
private void CloseFileStream(object state)
{
try
{
fileStream.Close(); // 尝试关闭文件流
Console.WriteLine($"Closed file stream after {TimeSpan.FromSeconds(5).TotalSeconds} seconds.");
}
catch (Exception ex)
{
Console.WriteLine($"Error closing file stream: {ex.Message}");
}
finally
{
// 重置定时器,以便再次运行
if (fileStreamClosingTimer != null && !fileStreamClosingTimer.IsCancelled)
fileStreamClosingTimer.Change(TimeSpan.FromSeconds(5), Timeout.InfiniteTimeSpan);
}
}
static void Main(string[] args)
{
Program program = new Program();
program.StartClosingSession();
// 程序主循环或等待操作...
}
}
