我现在想知道的是一个查询的. 像这个时间API,我怎么知道里面的属性呢?

以下都是调用API的C#例子33.读取ini文件属性//using System.Runtime.InteropServices;//[DllImport("kernel32")]//返回取得字符串缓冲区的长度//private static extern long GetPrivateProfileString(string section,string key, string def,StringBuilder retVal,int size,string filePath);string Section=%%1;string Key=%%2;string NoText=%%3;string iniFilePath="Setup.ini";string %%4=String.Empty;if(File.Exists(iniFilePath)){StringBuilder temp = new StringBuilder(1024);GetPrivateProfileString(Section,Key,NoText,temp,1024,iniFilePath);%%4=temp.ToString();}35.写入ini文件属性//using System.Runtime.InteropServices;//[DllImport("kernel32")]//返回0表示失败，非0为成功//private static extern long WritePrivateProfileString(string section,string key, string val,string filePath);string Section=%%1;string Key=%%2;string Value=%%3;string iniFilePath="Setup.ini";bool %%4=false;if(File.Exists(iniFilePath)){long OpStation = WritePrivateProfileString(Section,Key,Value,iniFilePath);  if(OpStation == 0){%%4=false;}else{%%4=true;}}83.注册全局热键注册全局热键要用到Windows的API方法RegisterHotKey和UnregisterHotKey。一、声明注册热键方法 [DllImport("user32.dll")]private static extern int RegisterHotKey(IntPtr hwnd, int id, int fsModifiers, int vk);[DllImport("user32.dll")]private static extern int UnregisterHotKey(IntPtr hwnd, int id);int Space = 32; //热键IDprivate const int WM_HOTKEY = 0x312; //窗口消息-热键private const int WM_CREATE = 0x1; //窗口消息-创建private const int WM_DESTROY = 0x2; //窗口消息-销毁private const int MOD_ALT = 0x1; //ALTprivate const int MOD_CONTROL = 0x2; //CTRLprivate const int MOD_SHIFT = 0x4; //SHIFTprivate const int VK_SPACE = 0x20; //SPACE二、注册热键方法 /// <summary>/// 注册热键/// </summary>/// <param name="hwnd">窗口句柄</param>/// <param name="hotKey_id">热键ID</param>/// <param name="fsModifiers">组合键</param>/// <param name="vk">热键</param>private void RegKey(IntPtr hwnd, int hotKey_id, int fsModifiers, int vk){bool result;if (RegisterHotKey(hwnd,hotKey_id,fsModifiers,vk) == 0){result = false;}else{result = true;}if (!result){MessageBox.Show("注册热键失败！");}}/// <summary>/// 注销热键/// </summary>/// <param name="hwnd">窗口句柄</param>/// <param name="hotKey_id">热键ID</param>private void UnRegKey(IntPtr hwnd, int hotKey_id){UnregisterHotKey(hwnd,hotKey_id);}三、重写WndProc方法，实现注册 protected override void WndProc(ref Message m){base.WndProc(ref m);switch(m.Msg){case WM_HOTKEY: //窗口消息-热键switch(m.WParam.ToInt32()){case 32: //热键IDMessageBox.Show("Hot Key : Ctrl + Alt + Shift + Space");break;default:break;}break;case WM_CREATE: //窗口消息-创建RegKey(Handle,Space,MOD_ALT | MOD_CONTROL | MOD_SHIFT,VK_SPACE); //注册热键break;case WM_DESTROY: //窗口消息-销毁UnRegKey(Handle,Space); //销毁热键break;default:break;}}84.菜单勾选/取消完成后关闭计算机/*using System.Runtime.InteropServices;[StructLayout(LayoutKind.Sequential, Pack = 1)]internal struct TokPriv1Luid{public int Count;public long

我现在想知道的是一个查询的. 像这个时间API,我怎么知道里面的属性呢?
