C# int to BCD encode(最简单的实现办法)BCD编码编程实现算法
这个函数是自己写的,不知道有误没有,网上找了很多但是都写得怪麻烦的。
希望对大家有所帮助
byteLength是返回字节的长度。
private static int GetSum(int baseInt, int[] sValue)
{
int count = sValue.Length;
if (count == 1) return sValue[0];
int r = 1;
int b = sValue[0];
for (int i = 1; i < count; i++)
{
r *= baseInt;
}
count--;
int[] ri = new int[sValue.Length - 1];
for (int j = 0; j < ri.Length; j++)
{
ri[j] = sValue[j + 1];
}
return b * r + GetSum(baseInt, ri);
}
public static byte[] BCDEncode(this int intvalue, int byteLength)
{
byte[] r = new byte[byteLength];
char[] chars = intvalue.ToString().ToCharArray();
int clengh = chars.Length;
int[] ints = new int[clengh];
for (int j = 0; j < clengh; j++)
{
ints[j] = Convert.ToInt32(chars[j].ToString());
}
int rvalue = GetSum(16, ints);
byte[] sas = BitConverter.GetBytes(rvalue);
byte[] ras = new byte[byteLength];
for (int k = 0; k < byteLength; k++)
{
ras[byteLength-k-1] = sas[k];
}
return ras;
}
