我已经制作了一个双筒,从我们的服务器中发送和检索数据包,我正在使用P/Invoke机制,从我负责所有必要任务的“C# app”中抽取一个小数功能。
当我打电话“联通”(char* lpPostData)
如果我使用Cchar* lpPostData作为从我C#的附录中发出的寄出的参数,要求它做工,则我使用静态的果园阵列作为邮寄要求。 C# string to char*? 如果是这样的话? 如何减少温32的死亡人数?
www.un.org/Depts/DGACM/index_spanish.htm 将出口职能从C# app上调:
[DllImport("testdllwm6.dll", EntryPoint = "Connect")] public
