The example of this article for everyone to share the micro-trust public platform to achieve access to the user OpenID method for your reference, the specific contents are as follows

Index.aspx.cs Code:

 Public partial class Index:System.Web.UI.Page {//user ID public string OpenID = "";
  The public number information section is publicly string AppID = configurationmanager.appsettings["AppID"];
  public string Appsecret = configurationmanager.appsettings["Appsecret"];
  public string Redirect_uri =httputility.urlencode ("http://www.jb51.net");

  public string scope = "" Delete this and fill in the request type, for example: Snsapi_userinfo "";
  #region Display page public string Accesstoken;
  public string Nickname;
  public string sex;
  public string Headimgurl;
  public string Province;
  public string Country;
  public string language;

  public, String city;
  public string privilege = ""; #endregion protected void Page_Load (object sender, EventArgs e) {/* micro-authentication access to the OpenID section: * Temporary authentication code *//
   Micro-Credit Certification section: The second step to obtain code string code = request["Code"]; if (string.
   IsNullOrEmpty (code) {//If the code is not successful, pull again openaccess (); //micro-Credit Certification section: Step three get OpenID string url = string. Format ("https://api.weixin.qq.com/sns/oauth2/access_tOken?appid={0}&amp;secret={1}&amp;code={2}&amp;grant_type=authorization_code ", AppID, Appsecret, code);
   string result = Httpclienthelper.getresponse (URL);
   Loghelper.writefile (result);

   Jobject outputobj = jobject.parse (result); Micro-Credit Certification section: Fourth step to get more information Accesstoken = outputobj["Access_token"].
   ToString (); OpenID = outputobj["OpenID"].
   ToString (); url = string. Format ("Https://api.weixin.qq.com/sns/userinfo?access_token={0}&amp;openid={1}&amp;lang=zh_cn", Accesstoken,
   OpenID);
   String result1 = Httpclienthelper.getresponse (URL);
   Loghelper.writefile (RESULT1); Jobject outputObj1 = Jobject.parse (RESULT1);//convert JSON to array//The following is the information obtained from step fourth: Nickname = outputobj1["nickname"]. ToString (); Nickname sex = outputobj1["Sex"]. ToString (); Gender of what Headimgurl = outputobj1["Headimgurl"]. ToString (); Avatar url province = outputobj1["province"].
    ToString ();; Country = outputobj1["Country"].
    ToString ();; Language = outputobj1["language"].
    ToString ();; City = outputobj1["City "].
   ToString ();;
   The user information obtained is filled into the session session["OpenID"] = outputobj1["OpenID"];
  Turning back to the entrance//openaccess (); * * * Access entry * open to micro-letter menu Call * @param $dir _url Source URL * @since 1.0 * @return void/public void OPENACC ESS () {//Judge session does not exist if (session["OpenID"] = = NULL) {//Authentication first step: Redirect Jump to authentication url string url = string.

   Response.Redirect (URL);
   //Judge session exists else {//Jump to front page. aspx Response.Redirect (Request.Url.ToString ());
