禁止輸入特殊字符正則表達試：
^(?:[/u4e00-/u9fa5]*/w*/s*)+$
過慮非法字符的函數：
public string CheckStr(string str)
{
str = str.Replace("<", "<");
str = str.Replace(">", ">");
str = str.Replace("'", "''");
str = str.Replace(" ", " ");
str = str.Replace("/n", "<br/>");
str = str.Replace("/r/n", "<br/>");
str = str.Trim();
return str;
