复制字节时出错 - 偏移量和长度超出范围。

Question

我试图将值的二维数组转换为一个字节[]并回到原始的二维数组。当运行我的代码我得到这个错误：

An unhandled exception of type 'System.ArgumentException' occurred in TestProject.exe. 

Additional information: Offset and length were out of bounds 
for the array or count is greater than the number of elements from the 
index to the end of the source collection. 

这里是我的代码：

byte[,] dataArray = new byte[,] { 
     {4, 6, 2}, 
     {0, 2, 0}, 
     {1, 3, 4} 
    }; 

    for (int j = 0; j < 3; j++) 
    { 
     for (int i = 0; i < 3; i++) 
     { 
      Console.WriteLine("Value[" + i + ", " + j + "] = " + dataArray[j, i]); 
     } 
    } 
    long byteCountArray = dataArray.GetLength(0) * dataArray.GetLength(1) * sizeof(byte); 

    var bufferByte = new byte[byteCountArray]; 

    Buffer.BlockCopy(dataArray, 0, bufferByte, 0, bufferByte.Length); 

    //Here is where I try to convert the values and print them out to see if the values are still the same: 

    byte[] originalByteValues = new byte[bufferByte.Length/2]; 
    Buffer.BlockCopy(bufferByte, 0, originalByteValues, 0, bufferByte.Length); 
    for (int i = 0; i < 5; i++) 
    { 
     Console.WriteLine("Values---: " + originalByteValues[i]); 
    } 

在Buffer.BlockCopy行出现的错误：

Buffer.BlockCopy(bufferByte, 0, originalByteValues, 0, bufferByte.Length); 

我是新来的编程/转换字节，所以任何帮助表示赞赏。

Answer 1

正在制作的阵列过小，有一半的大小，你要复制

new byte[bufferByte.Length/2]; 

似乎应该是

new byte[bufferByte.Length];
