获取sim卡信息出现异常-无法找到 PInvoke DLL“cellcore.dll“
win ce 获取sim卡信息出现异常-无法找到 PInvoke DLL“cellcore.dll“
Common c=new Common();//封装sim相关信息的类
txtIMEI.Text = c.GetAllSection();//获取sim卡所有信息
问题：在调用方法 GetAllSection 获取sim卡信息时，执行到方法下面这句出现 无法找到 PInvoke DLL“cellcore.dll“的异常：
res = SimInitialize(IntPtr.Zero, IntPtr.Zero, IntPtr.Zero, out hSim);
