在C#中将二维数组转换为单维数？

Question

我在C#中将2维数组转换为单维数据.我从设备(C++)接收二维数组,然后在C#中将其转换为1维.这是我的代码:

int iSize = Marshal.SizeOf(stTransactionLogInfo); //stTransactionLogInfo is a structure
byte[,] bData = (byte[,])objTransLog; //objTransLog is 2 dimensionl array from device
byte[] baData = new byte[iSize];

for (int i = 0; i < bData.GetLength(0); i++)
{
    for (int j = 0; j < iSize; j++)
    {
        baData[j] = bData[i, j];
    }
}

我从上面的代码中得到了所需的结果,但问题是它不是标准的实现方式.我想知道如何以标准方式完成.可能正在进行编组,我不确定.提前致谢.

Answer 1

您可以使用Buffer.BlockCopy方法:

byte[,] bData = (byte[,])objTransLog;

byte[] baData = new byte[bData.Length];

Buffer.BlockCopy(bData, 0, baData, 0, bData.Length);

例:

byte[,] bData = new byte[4, 3]
{ 
    {  1,  2,  3 }, 
    {  4,  5,  6 }, 
    {  7,  8,  9 }, 
    { 10, 11, 12 } 
};

byte[] baData = new byte[bData.Length];

Buffer.BlockCopy(bData, 0, baData, 0, bData.Length);

// baData == { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 }

最简单的方法

int iSize = Marshal.SizeOf(stTransactionLogInfo); //stTransactionLogInfo is a structure
byte[,] bData = (byte[,])objTransLog; //objTransLog is 2 dimensionl array from device
byte[] baData = bData.Cast<byte>().ToArray();
