c#中修改时间的问题
在c#中如果我要修改本地时间应该用什么类阿? 
 我找了半天没找到,难道非要用win32API吗?

------解决方案--------------------常见的做法还是下面, 
 [DllImport( "Kernel32.dll ")]  
 private static extern bool SetSystemTime( ref SystemTime sysDate );  
 [DllImport( "Kernel32.dll ")]  
 private static extern void GetSystemTime(ref SystemTime sysDate);    
 public static void SetSystemDate(System.DateTime newDate) 
 { 
 	SystemTime sysDate = new SystemTime();    
 	GetSystemTime(ref sysDate);   
 	sysDate.wYear = (ushort)newDate.Year;  
 	sysDate.wMonth = (ushort)newDate.Month;  
 	sysDate.wDay = (ushort)newDate.Day;    
 	SetSystemTime(ref sysDate);  
 }
