C#调用SDK

C#如何调用别人开发的SDK工具包呢？或者推荐一下相关的教材！谢谢！

Answer 1

using System.Runtime.InteropServices;
[DllImport("HCNetSDK.dll")]

public static extern bool NET_DVR_ClientSetVideoEffect(int lRealHandle, uint dwBrightValue, uint dwContrastValue, uint dwSaturationValue, uint dwHueValue);

[DllImport("HCNetSDK.dll")]

public static extern bool NET_DVR_ClientGetVideoEffect(int lRealHandle, uint pBrightValue, uint pContrastValue, uint pSaturationValue, uint pHueValue);

[DllImport("HCNetSDK.dll")]

public static extern bool NET_DVR_RigisterDrawFun(int lRealHandle, DrawFun x, uint dwUser);

[DllImport("HCNetSDK.dll")]

public static extern bool NET_DVR_SetPlayerBufNumber(int lRealHandle, uint dwBufNum);

[DllImport("HCNetSDK.dll")]

public static extern bool NET_DVR_ThrowBFrame(int lRealHandle, uint dwNum);

Answer 2

调用非托管DLl函数using systtem.runtime.xxx;

翻译如下：
[DllImport("xxx.dll")]
public static extern int Sms_Connect (string pServer,int lCorpID,string pLoginName,string pPasswd,int lTimeOut,int HWND);
[DllImport("xxx.dll")]
public static extern void Sms_DisConnect();
[DllImport("xxx.dll")]

public static extern int Sms_Send(string pMobile,string pMsg,ref int lSmsID);
[DllImport("xxx.dll")]
public static extern int Sms_Get(string pNo,string pMsg,string pTime);
