//读取双层的
string[,] dd = new string[0,0];
Response.Write(V.mycookie_twoTime("SONHOOCOOKIE", "sonhoogsid",dd , "read", 1));

//设置双层COOKIE
    string[,] sonhoocookie = new string[3, 2];
    sonhoocookie[0, 0] = "sonhoogsid";//变量名
    sonhoocookie[0, 1] = userid;//变量值
    sonhoocookie[1, 0] = "sonhooqymc";//变量2名
    sonhoocookie[1, 1] = "华和兴创想科技";//变量2值
<pre name="code" class="csharp">    sonhoocookie[2, 0] = "sonhooqymc2";
    sonhoocookie[2, 1] = "华和兴创想科技";
V.mycookie_twoTime("SONHOOCOOKIE", "", sonhoocookie, "set", 1);
