关于C#与(C++)Com交互之数组传递

通过C#分配内存空间给COM

void SetDataToCom()

     {

                var arrayy = new int[3]{1,2,3};

                int size = Marshal.SizeOf(arrayy[0]) * arrayy.Length;
                marshalDataList = Marshal.AllocHGlobal(size);
                Marshal.Copy(arrayy, 0, marshalDataList, arrayy.Length);

                Mycom.SetCom(marshalDataList, arrayy.Length, false);//Set Value To Com

      }

void GetDataFormCom()

{

                int[] dataList = new int[10];
                int size = Marshal.SizeOf(dataList[0]) * dataList.Length;
                marshalDataList = Marshal.AllocHGlobal(size);

                Mycom.GetCom(marshalDataList, dataList.Length, true);//Get Value From Com
                Marshal.Copy(marshalDataList, dataList, 0, dataList.Length);

}
