C# how to sync windows 10 PC with CMD which needs administrator right?

Question

Hello:
I have an issue with my Windows 10 PC when it goes into hibrate state.
During launch time, I usually set my Windows 10 PC go into hibrate state.
After launch, when I come back to work in the office, the clock seems to be a few seconds off the correct time, I have to manually sync the clock.
However, if I setup windows times service to start automatically, I can run the following DOS command to sync clock of my PC, like this:
C:\WINDOWS\system32>w32tm /resync
Sending resync command to local computer
The command completed successfully.
If I run without administrator privilage, the above command failed.
I want to write a simple C# program, which can call this simple command to sync clock of my PC, but the program has to be run with administrator privilages.
Please advise what should do?
My OS: Windows 10 Pro (Version 21H2).
Thanks,

Hi @john zyd , Welcome to Microsoft Q&A, you could try the following code to get what you wanted.

private void button1_Click(object sender, EventArgs e)  
{  
	MessageBox.Show(Execute(""));//(Your dos command)  
}  
  
//dosCommand Dos command statement  
public string Execute(string dosCommand)   
{  
	return Execute(dosCommand, 10);  
}  
/// <summary>  
/// Execute the DOS command and return the output of the DOS command  
/// </summary>  
/// <param name="dosCommand">dos command</param>  
/// <param name="milliseconds">Waiting for the command execution time (unit: milliseconds),  
/// If set to 0, wait indefinitely</param>  
/// <returns>Returns the output of the DOS command</returns>  
public static string Execute(string command, int seconds)   
{  
	string output = "";  
	//output string  
	if (command != null && !command.Equals(""))   
	{  
		Process process = new Process();  
		//Create a process object  
		ProcessStartInfo startInfo = new ProcessStartInfo();  
		startInfo.FileName = "cmd.exe";  
		//Set the command to be executed  
		startInfo.Arguments = "/C " + command;  
		//"/C" means exit immediately after executing the command  
		startInfo.UseShellExecute = false;  
		//Do not use the system shell to start  
		startInfo.RedirectStandardInput = false;  
		//Do not redirect input  
		startInfo.RedirectStandardOutput = true;  
		// redirect output  
		startInfo.CreateNoWindow = true;  
		//Do not create a window  
		process.StartInfo = startInfo;  
		try   
		{  
			if (process.Start())//Start the process   
			{  
				if (seconds == 0)   
				{  
					process.WaitForExit();  
					//Here infinite waiting for the process to end  
				} else   
				{  
					process.WaitForExit(seconds);  
					//Wait for the process to end, the waiting time is the specified milliseconds  
				}  
				output = process.StandardOutput.ReadToEnd();  
				//Read the output of the process  
			}  
		}  
		catch   
		{  
		}  
		finally   
		{  
			if (process != null)  
			process.Close();  
		}  
	}  
	return output;  
}
