获得汉字的区位码
byte[] array = new byte[2];
array = System.Text.Encoding.Default.GetBytes("啊");
int i1 = (short)(array[0]-"\0");
int i2 = (short)(array[1]-"\0");
unicode解码方式下的汉字码
array = System.Text.Encoding.Unicode.GetBytes("啊");
i1 = (short)(array[0]-"\0");
i2 = (short)(array[1]-"\0");
unicode反解码为汉字
string str = "4a55";
string str1 = str.Substring(0,2);
srting str2 = 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 = "ABC一二三";
int len = s.Length;//结果为6
byte[] sarr = System.Text.Encoding.Default.GetBytes(s);
len = sarr.Length;//结果为3+3*2=9
字符串相加
System.Text.StringBuilder sb = new System.Text.StringBuilder("");
sb.Append("A");
sb.Append("BC");
sb.Append("一二三"); |
