远程桌面连接在一小时会话后会断开。

要解决远程桌面连接在一小时会话后会断开的问题，可以通过修改远程桌面连接的超时设置来延长连接时间。下面是一个示例的解决方法，使用C#编写一个控制台应用程序来修改远程桌面连接的超时设置：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;

namespace RemoteDesktopTimeout
{
    class Program
    {
        // 调用Windows API函数来设置远程桌面连接的超时时间
        [DllImport("user32.dll", SetLastError = true)]
        private static extern int GetTickCount();

        [DllImport("Wtsapi32.dll", SetLastError = true)]
        private static extern bool WTSQuerySessionInformation(
            IntPtr hServer,
            int sessionId,
            WTS_INFO_CLASS infoClass,
            out IntPtr ppBuffer,
            out int pBytesReturned
        );

        [DllImport("Wtsapi32.dll")]
        private static extern void WTSFreeMemory(IntPtr pMemory);

        [DllImport("Wtsapi32.dll", SetLastError = true)]
        private static extern bool WTSQueryUserToken(int sessionId, out IntPtr phToken);

        [DllImport("user32.dll")]
        private static extern bool ExitWindowsEx(uint uFlags, uint dwReason);

        private enum WTS_INFO_CLASS
        {
            WTSInitialProgram,
            WTSApplicationName,
            WTSWorkingDirectory,
            WTSOEMId,
            WTSSessionId,
            WTSUserName,
            WTSWinStationName,
            WTSDomainName,
            WTSConnectState,
            WTSClientBuildNumber,
            WTSClientName,
            WTSClientDirectory,
            WTSClientProductId,
            WTSClientHardwareId,
            WTSClientAddress,
            WTSClientDisplay,
            WTSClientProtocolType
        }

        private static void SetRemoteDesktopTimeout(int sessionId, int timeoutMinutes)
        {
            IntPtr buffer;
            int bytesReturned;
            if (WTSQuerySessionInformation(IntPtr.Zero, sessionId, WTS_INFO_CLASS.WTSSessionId, out buffer, out bytesReturned))
            {
                int sessionID = Marshal.ReadInt32(buffer);
                WTSFreeMemory(buffer);

                // 获取当前会话的用户令牌
                IntPtr userToken;
                if (WTSQueryUserToken(sessionID, out userToken))
                {
                    // 设置远程桌面连接的超时时间
                    uint timeout = (uint)(timeoutMinutes * 60 * 1000); // 超时时间以毫秒为单位
                    uint flags = 0;
                    if (!ExitWindowsEx(flags, timeout))
                    {
                        Console.WriteLine("Failed to set remote desktop timeout.");
                    }

                    Marshal.CloseHandle(userToken);
                }
                else
                {
                    Console.WriteLine("Failed to get user token.");
                }
            }
            else
            {
                Console.WriteLine("Failed to query session information.");
            }
        }

        static void Main(string[] args)
        {
            // 设置远程桌面连接的超时时间为2小时（120分钟）
            SetRemoteDesktopTimeout(0, 120);

            Console.WriteLine("Remote desktop timeout has been set.");
            Console.ReadLine();
        }
    }
}

这段代码使用了Windows API函数来查询当前会话的用户令牌，并使用ExitWindowsEx函数设置远程桌面连接的超时时间。在Main方法中，我们通过调用SetRemoteDesktopTimeout方法来设置超时时间为2小时（120分钟）。你可以根据需要修改超时时间。运行该应用程序后，它会打印出"Remote desktop timeout has been set."的消息，表示超时时间已成功设置。
