C#后台数组传到前台的javascript
public class info {
            public int Cai_No = 0;
            public string Cai_Name = "";
            public int Price = 0;
        }
        public info[] myinfo=new info[50];
        public void SetInfo()
        {
            for(int i=0;i<cai_count;++i)
            {
                myinfo[i] = new info();
                myinfo[i].Cai_No = int.Parse(cai_info[0, i]);
                myinfo[i].Cai_Name = cai_info[1, i];
                myinfo[i].Price = int.Parse(cai_info[4, i]);
            }
}
for (var i = 0; i < cai_count ; i++) {
        cai[i] = new Array();
        document.cookie = "Count="+i;
        cai[i][0] = "<%=myinfo[i].Cai_No%>";
            cai[i][1] = "<%=myinfo[i].Cai_Name%>";
            cai[i][2] = "<%=myinfo[i].Price%>";
        }
下边传进来不能用i这类变量，该怎么办？

转成json字符再给js不好吗?

不会用...

去网上找数组转JSON的类，在通过输出respose到前台，解析JSON.

后台代码
Dictionary<int, object> installlist = installBll.GetInstallInfo(company.CompanyID, null);
      for (int i = 1; i < 13; i++){
                                if (installlist.ContainsKey(i)){
                                    installs += i + "," + installlist[i] + ";";
                                }
                }
     txtInstallInfo.Value = installs;
前台代码
  <input type="hidden" id="txtInstallInfo" runat="server" />
   <script type="text/javascript">
            jQuery(document).ready(function () {
                var installs = document.getElementById("txtInstallInfo").value;
//转为数组
                eval("var Install=[[" + installs.replace(/;/gi, '],[') + "]]");
}）

JSON使用后台传值前台里面有简单的例子

又是一个没把前后端分清的

对于后端来说前台的东西都是字符串，服务器生成字符串发送给浏览器
js只有到了浏览器那边才会被当成脚本运行

你想在js传递参数给服务器程序，需要通过ajax，上面说的json就是ajax里常用的一种数据格式
