C# 将一维数组拼接成按7bit为单元，高位填0的数组

从二维数组中取一行数据

public byte[] GetLineByte(byte[,] bbArray, int iLine)
{
	int iCols = bbArray.GetLength(0);  //列
	byte[] bLineData = new byte[iCols];

	for (int i = 0; i < iCols; i++)
	{
		bLineData[i] = bbArray[i, iLine];
	}

	return bLineData;
}

字节数组转16进制字符串 

public string byteToHexStr(byte[] bytes)
{
	string returnStr = "";
	if (bytes != null)
	{
		for (int i = 0; i < bytes.Length; i++)
		{
			returnStr += bytes[i].ToString("X2");
		}
	}
	return returnStr;
