构思：

在首页（MainPage）上定义一个代表应用版本号的字符串，网站上写一个接口（让这个字符串与你的最新应用版本号进行比较，返回应用的ContentIdentifier与操作状态什么的）。

一、wp客户端

//下次进入应用继续提示升级 SQLiteHelper.openDB();
SQLiteHelper.CreateVersionTable();

mp.ContentIdentifier = urlVer;
mp.Show();
}
else if (mbr == MessageBoxResult.Cancel) {
//记住此次启动应用后用户的选择即不升级 SQLiteHelper.openDB();
SQLiteHelper.CreateVersionTable();
VersionInfo infoVersion = SQLiteHelper.seleceVersion();
if (infoVersion != null)//判断VersionInfo中是否为空 {
infoVersion.IsUpdate = 1;
SQLiteHelper.UpdateVersionData(infoVersion);

catch (Exception e) {

using System.Web.UI;
using System.Web.UI.WebControls;
using phone.BizComponents;

protected void Page_Load(object sender, EventArgs e) {
UpgradeBiz biz=new UpgradeBiz();
string result = " ";
string strInfo="";
string ver = Request.QueryString["ver"];
if (ver != null && ver != "") {
string[] verArr = ver.Split('_');
//"Microsoft_Winphone_V1.0.0" if (verArr.Length==3) {
string org = verArr[0];
string cate = verArr[1];
string version=verArr[2];
//通过机构名，类型，版本号与数据库进行比较，判断升级 //SELECT top 1 Id,ORG,Category,[Version],Must,Url,AddTime FROM M_T_PHONE_Upgrade WHERE ORG=@ORG and Category=@Category and [Version]>@Version order by AddTime desc,Id desc;
DataTable table = biz.GetNewVersion(org, cate, version);
if (table.Rows.Count>0) {
string isMust =Convert.ToString(table.Rows[0]["Must"]);
string url = Convert.ToString(table.Rows[0]["url"]);
string strNewVer = string.Format("{
0}
_{
1}
_{
2}
", table.Rows[0]["ORG"], table.Rows[0]["Category"], table.Rows[0]["Version"]);
result = string.Format("{
0}
|{
1}
",isMust,url);
string strMust=isMust=="1"?"选择升级":"强制升级";
strInfo = string.Format("【{
0}
|{
1}
到{
2}
】|{
3}
", strMust,ver,strNewVer, url);
}
else {
result = "0";
}
}
}
Response.Write(result);
}
}
