asp.net中怎么自定義會話管理，相信很多沒有經驗的人對此束手無策，為此本文總結了問題出現的原因和解決方法，通過這篇文章希望你能解決這個問題。
/// <summary>
/// 微信會話記錄類，用戶存儲會話記錄列表
/// </summary>
public class WeixinKeFuInfo
{
public int UId { get; set; }//編號
public string UserOpenId { get; set; }//用戶的OpenID
public string UserContent { get; set; }//用戶內容
public string CreaterDate { get; set; }//創建時間
}
/// <summary>
/// 與微信用戶會話的消息記錄類
/// </summary>
public class WxMessageInfo
{
public int msgId { get; set; }//消息ID
public string FromUser { get; set; }//發送用戶
public string ToUser { get; set; }//接收用戶
public string Content { get; set; }//發送內容
public string FaSongDate { get; set; }//發送時間
public string UId { get; set; }//會話用戶的UId,微信會話記錄類外鍵
}
/// <summary>
/// 發送文本。。。。。。。。。。。。。還記得這個方法嗎？就是根據用戶發送過來的消息類型進行判斷后，如果是文本就回復發送此方法內的內容
/// </summary>
/// <param name="requestXML"></param>
private void SendTextCase(RequestXML requestXML)
{
WeixinKeFuService wkfs = new WeixinKeFuService();//自己寫的服務類
//根據openId查詢數據庫會話記錄是否存在
WeixinKeFuInfo wkfinfoinfo = wkfs.GetWeixinKeFuInfoByOpenId(requestXML.FromUserName.ToString());
if (wkfinfoinfo != null)
{
//如果存在直接保存消息記錄
WxMessageService wms = new WxMessageService();
WxMessageInfo wminfo = new WxMessageInfo();
wminfo.FromUser = requestXML.FromUserName.ToString();
wminfo.ToUser = "我";
wminfo.Content = requestXML.Content.ToString();
wminfo.FaSongDate = System.DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss");
wminfo.UId = wkfinfoinfo.UId.ToString();
wms.AddWxMessageInfo(wminfo);
}
else
{
//如果不存在新建會話記錄
WeixinKeFuInfo wkfinfo = new WeixinKeFuInfo();
wkfinfo.UserOpenId = requestXML.FromUserName.ToString();
wkfinfo.UserContent = requestXML.Content.ToString();
wkfinfo.CreaterDate = System.DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss");
wkfs.AddWeixinKeFuInfo(wkfinfo);
string responseContent = FormatTextXML(requestXML.FromUserName, requestXML.ToUserName, "正在接入.請稍候.....");
HttpContext.Current.Response.ContentType = "text/xml";
HttpContext.Current.Response.ContentEncoding = Encoding.UTF8;
HttpContext.Current.Response.Write(responseContent);
HttpContext.Current.Response.End();
}
}以上代碼實現了數據庫的插入，那么取出來，顯示的頁面，核心代碼：WeiXinSessionList.aspx，前臺代碼如下：
