通过Ajax和鉴权删除记录的方法

-
几个部分：
1、页面CS代码实现动态生成删除按钮
2、页面Aspx代码实现Ajax调用
3、枚举定义
4、AjaxDeleteSlowXItem的Handler实现删除
5、相关的鉴权代码
-

System.Configuration.ConfigurationManager.AppSettings
["SlowX.WebSite.BLL.WebSiteBasicBLL.pageSignKey"];

public string GetGB2312MD5(string s)
{
if (s == null)
s = "";
MD5 md5 = new MD5CryptoServiceProvider();
byte[] t = md5.ComputeHash(System.Text.Encoding.GetEncoding("GB2312").GetBytes(s));
StringBuilder sb = new StringBuilder(32);
for (int i = 0; i < t.Length; i++)
{
sb.Append(t[i].ToString("x").PadLeft(2, '0'));
}
return sb.ToString();
}
