可以使用System.ServiceProcess.ServiceController這個類允許連接到正在運行或者已停止的服務、對其進行操作或獲取有關它的信息。ServiceController 提供了開始和停止服務的方法（Start, Stop）。
但是這個類並沒有提供修改服務啟動類型的方法，可以通過C#調用cmd來修改
參考網上的這個方法：
//設置服務的啟動類型
//sServiceName服務名稱
//iStartType要設置的啟動類型 2：自動，3：手動，4：禁用
//返回成功狀態 true：成功，false：失敗
代碼如下：
public Boolean SetWindowsServiceStartType(String sServiceName, int iStartType)
{
try
{
System.Diagnostics.ProcessStartInfo objProcessInf = new System.Diagnostics.ProcessStartInfo();
objProcessInf.FileName = "cmd.exe";
objProcessInf.CreateNoWindow = false;
objProcessInf.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
string sStartState = "boot";
switch (iStartType)
{
case 1:
{
sStartState = "system";
break;
}
case 2:
{
sStartState = "auto";
break;
}
case 3:
{
sStartState = "demand";
break;
}
case 4:
{
sStartState = "disabled";
break;
}
default:
{
break;
}
}
objProcessInf.Arguments = "/c sc config " + sServiceName + " start= " + sStartState;
System.Diagnostics.Process.Start(objProcessInf);
return true;
}
catch
{
return false;
}
}
