我个人认为应该有一个字符表，即汉字的拼音表。这样比较麻烦，或者直接引用windows内的字符表。

建立一个表，每个拼音都跟多个汉字对应。可以通过汉字，找出对应的一个拼音，也可以通过拼音，找出一堆汉字。
public string hz2py(string hz) //获得汉字的区位码
{
byte[] sarr = System.Text.Encoding.Default.GetBytes(hz);
int len = sarr.Length;
if (len1)
{
byte[] array = new byte[2];
array = System.Text.Encoding.Default.GetBytes(hz);
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(hz);
// int i1 = (short)(array[0] - '\0');
// int i2 = (short)(array[1] - '\0');
// int t1 = Convert.ToInt32(i1,16);
// int t2 = Convert.ToInt32(i2,16);
int tmp=i1*256+i2;
