byte[] array = new byte[2]; array = System.Text.Encoding.Default.GetBytes("啊"); int i1 = (short)(array[0] - " "); int i2 = (short)(array[1] - " "); //unicode解码方式下的汉字码 array = System.Text.Encoding.Unicode.GetBytes("啊"); i1 = (short)(array[0] - " "); i2 = (short)(array[1] - " "); //unicode反解码为汉字 string str = "4a55"; string s1 = str.Substring(0,2); string s2 = str.Substring(2,2); int t1 = Convert.ToInt32(s1,16); int t2 = Convert.ToInt32(s2,16); array[0] = (byte)t1; array[1] = (byte)t2; string s = System.Text.Encoding.Unicode.GetString(array); //default方式反解码为汉字 array[0] = (byte)196; array[1] = (byte)207; s = System.Text.Encoding.Default.GetString(array); //取字符串长度 s = "iam方枪枪"; int len = s.Length;//will output as 6 byte[] sarr = System.Text.Encoding.Default.GetBytes(s); len = sarr.Length;//will output as 3+3*2=9 //字符串相加 System.Text.StringBuilder sb = new System.Text.StringBuilder(""); sb.Append("i "); sb.Append("am "); sb.Append("方枪枪");  源代码网供稿. |
