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?

Question

看好问题,别复制.我要的是一个能查找到API名字啊,和API都有什么成员.比如说[DllImport("kernel32.dll")] public static extern void GlobalMemoryStatus(ref MEMORY_INFO meminfo); [StructLayout(LayoutKind.Sequential)] public struct SYSTEMTIME_INFO { public ushort wYear; public ushort wMonth; public ushort wDayOfWeek; public ushort wDay; public ushort wHour; public ushort wMinute; public ushort wSecond; public ushort wMilliseconds; } 我怎么能知道内存的API是kernel32.dll 和里面有的属性

Answer 1

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ID
private 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; //ALT
private const int MOD_CONTROL = 0x2; //CTRL
private const int MOD_SHIFT = 0x4; //SHIFT
private 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ID
MessageBox.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;
}
}

Answer 2

如果查看所有进程的DLL文件,运行CMD:
tasklist /m
运行后显示所有进程加载的DLL文件.
假如我们查看进程iexplore.exe调用或加载的模块文件,运行:
tasklist /m iexplore.exe
运行后显示所有该应用程序的DLL文件. 

查看DLL:
一个很简单的方法就是用.NET自带的命令行工具

1.首先启动vs的命令行工具

2.定位到你的DLL的那个目录

3.然后输入" ildasm a.dll；注意：a.dll是你的dll的名字 就可以了

不知你问的是不是这个
希望能帮上你
