C#结构体中的数据怎么样快速存入数组中

结构体里定义了146条数据需要存入到数组中，我现在不会写，一条条往里写，有么有类似buffer.blockcopy的指令，或者用循环也可以

                                int count = Convert.ToInt32(sArray[2]);
                                byte[] buffer = new byte[count];
                                tempSocketSend.Receive(buffer, count, SocketFlags.None);
                                Q30Data a = new Q30Data();
                                a = (Q30Data)Utils.BytesToStuct(buffer, typeof(Q30Data));
                                byte[,] data = new byte[1800, 146];
                                data[cont, 0] = a.data1;
                                data[cont, 1] = a.data2;
                                data[cont, 2] = a.data3;
                                data[cont, 3] = a.data4;
                                data[cont, 4] = a.data5;
                                data[cont, 5] = a.data6;
                                data[cont, 6] = a.data7;
                                data[cont, 7] = a.data8;
                                data[cont, 8] = a.data9;
                                data[cont, 9] = a.data10;
                                data[cont, 10] = a.data11;
                                data[cont, 11] = a.data12;
                                data[cont, 12] = a.data13;
                                data[cont, 13] = a.data14;
