将二维数组转换为 C# 中的一维数组? [英] Converting 2 dimensional array to Single dimensional in C#?

问题描述

我在 C# 中将二维数组转换为一维数组.我从设备(C++)接收二维数组，然后在 C# 中将其转换为一维数组.这是我的代码:

I am converting 2dimensional array to Single dimensional in C#. I receive the 2 dimensional array from device (C++) and then I convert it to 1 dimensional in C#. Here is my code:

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想要的结果，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.可能正在做编组，我不确定.提前致谢.

I get the desired result from above code, but the problem is it is not the standard way of implementation. I want to know how it can be done in a standard way. May be doing Marshalling , I am not sure. Thanks in advance.

推荐答案

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);

示例:

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 }
