这个主要用于格式化通信数据数组.

private void button6_Click(object sender, EventArgs e)
{byte[] l_bytes = new byte[4];l_bytes[0] = 154;l_bytes[1] = 153;l_bytes[2] = 33;l_bytes[3] = 65;StringBuilder ret = new StringBuilder();foreach (byte b in l_bytes){//{0:X2} 大写, {0:x2} 小写//这里以空格分割ret.AppendFormat("{0:X2}{1}", b, " ");}Console.WriteLine("{0}", ret.ToString());
}
