看好問題,別復(fù)制.我要的是一個(gè)能查找到API名字啊,和API都有什么成員.比如說[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; } 我怎么能知道內(nèi)存的API是kernel32.dll 和里面有的屬性

以下都是調(diào)用API的C#例子
33.讀取ini文件屬性
//using System.Runtime.InteropServices;
//[DllImport("kernel32")]//返回取得字符串緩沖區(qū)的長(zhǎng)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.寫入ini文件屬性
//using System.Runtime.InteropServices;
//[DllImport("kernel32")]//返回0表示失敗，非0為成功
//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.注冊(cè)全局熱鍵
注冊(cè)全局熱鍵要用到Windows的API方法RegisterHotKey和UnregisterHotKey。
一、聲明注冊(cè)熱鍵方法 [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; //熱鍵ID
private const int WM_HOTKEY = 0x312; //窗口消息-熱鍵
private const int WM_CREATE = 0x1; //窗口消息-創(chuàng)建
private const int WM_DESTROY = 0x2; //窗口消息-銷毀
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、注冊(cè)熱鍵方法 /// <summary>
/// 注冊(cè)熱鍵
/// </summary>
/// <param name="hwnd">窗口句柄</param>
/// <param name="hotKey_id">熱鍵ID</param>
/// <param name="fsModifiers">組合鍵</param>
/// <param name="vk">熱鍵</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("注冊(cè)熱鍵失??！");
}
}

/// <summary>
/// 注銷熱鍵
/// </summary>
/// <param name="hwnd">窗口句柄</param>
/// <param name="hotKey_id">熱鍵ID</param>
private void UnRegKey(IntPtr hwnd, int hotKey_id)
{
UnregisterHotKey(hwnd,hotKey_id);
}
三、重寫WndProc方法，實(shí)現(xiàn)注冊(cè) protected override void WndProc(ref Message m)
{
base.WndProc(ref m);
switch(m.Msg)
{
case WM_HOTKEY: //窗口消息-熱鍵
switch(m.WParam.ToInt32())
{
case 32: //熱鍵ID
MessageBox.Show("Hot Key : Ctrl + Alt + Shift + Space");
break;
default:
break;
}
break;
case WM_CREATE: //窗口消息-創(chuàng)建
RegKey(Handle,Space,MOD_ALT | MOD_CONTROL | MOD_SHIFT,VK_SPACE); //注冊(cè)熱鍵
break;
case WM_DESTROY: //窗口消息-銷毀
UnRegKey(Handle,Space); //銷毀熱鍵
break;
default:
break;
}
}

如果查看所有進(jìn)程的DLL文件,運(yùn)行CMD:
tasklist /m
運(yùn)行后顯示所有進(jìn)程加載的DLL文件.
假如我們查看進(jìn)程iexplore.exe調(diào)用或加載的模塊文件,運(yùn)行:
tasklist /m iexplore.exe
運(yùn)行后顯示所有該應(yīng)用程序的DLL文件. 

查看DLL:
一個(gè)很簡(jiǎn)單的方法就是用.NET自帶的命令行工具

1.首先啟動(dòng)vs的命令行工具

2.定位到你的DLL的那個(gè)目錄

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

不知你問的是不是這個(gè)
希望能幫上你
