Question

我正在使用MVC5 ASP.NET创建一个网站。我正在使用Identity framework 2.0实现类，其中包含passwordhash，username，email，emailconfirmed等属性。我正在使用userManager.ChangePassword（user.Id，Oldpassword，Newpassword）;但我无法弄清楚我应该如何从用户那里获取密码作为纯文本（字符串）

    [HttpPost]
    public ActionResult ChangePassword(AspNetUsersViewModel userView)
    {

        UserManager<IdentityUser> userManager = new UserManager<IdentityUser>(new UserStore<IdentityUser>());

        var result = userManager.ChangePassword(_User.Id, "123456789", userView.Password);

        return RedirectToAction("Index", "ConfigUser");

    }

就像现在我已经硬编码用户当前密码“123456789”来测试它是否有效，它确实如此。我希望你们能帮忙。

将密码输入添加到表单标记内的View

    protected void Page_Load(object sender, EventArgs e)
    {


        if (Session["user"] == null)
            Response.Redirect("~/default.aspx");

        if (Request .QueryString ["action"]=="edit")
        {
            Panel1.Visible = true;
        }

        if (Request.QueryString["edit"] != null)
        {


            Panel1.Visible = true;
            SqlConnection con2 = new SqlConnection();
            con2.ConnectionString =GNews.Properties.Settings.Default.connectionstring;
            DataTable dt3 = new DataTable();
            con2.Open();
            SqlDataReader myReader = null;
            SqlCommand myCommand = new SqlCommand("select * from loadpost_view where Postid=" + Request.QueryString["edit"].ToString () + "", con2);
            myReader = myCommand.ExecuteReader();



            while (myReader.Read())
            {
                title_txt.Text=myReader ["Title"].ToString ();
                bodytxt.Text = myReader["Body"].ToString();
            }
            con2.Close();
        }
protected void btn_addpost_Click(object sender, EventArgs e)
    {
string title= title_txt .Text ;
string body=bodytxt .Text ;

if (Request.QueryString["edit"] != null)
{
    string message;

    string filename = thumb_uploader.FileName;
    string path = HttpContext.Current.Server.MapPath("~") + "\\Thumb";
    string exup = System.IO.Path.GetExtension(thumb_uploader.FileName);
    string[] ext = { ".jpg", ".png", ".jpeg" };
    if (Array.IndexOf(ext, exup) < 0)
    {
        message = "not correct.";
    }

    if (thumb_uploader.FileBytes.Length / 1024 > 400)
    {
        message = "not currect.";
    }

    while (System.IO.File.Exists(path + "\\" + filename + exup))
    {
        filename += "1";
    }

    savepath = path + "\\" + filename;

    if (thumb_uploader.HasFile)
    {
        thumb_uploader.SaveAs(savepath);

        thumb = thumb_uploader.FileName;
        SqlCommand command;
        SqlDataAdapter da;
        SqlConnection con3 = new SqlConnection();

        con3.ConnectionString = GNews.Properties.Settings.Default.connectionstring;
        command = new SqlCommand();
        command.Connection = con3;
        da = new SqlDataAdapter();
        da.SelectCommand = command;

        command.CommandText = "UPDATE tbl_post SET Title=@title ,Body=@body ,Thumb=@thu Where Postid=" + Request.QueryString["edit"].ToString();
        con3.Open();
        command.Parameters.AddWithValue("@title", title );
        command.Parameters.AddWithValue("@body", body );
        command.Parameters.AddWithValue("@thu", thumb_uploader .FileName);

        command.ExecuteNonQuery();
        con3.Close();
        message = "its ok.";
        lbl_result.Text = message;
   }
   else
   {
        using (SqlConnection con3 = new SqlConnection(GNews.Properties.Settings.Default.connectionstring))
        {
            string sql = "update tbl_post SET Title=@title ,Body=@body  Where Postid=@postid" ;
            using (SqlCommand command = new SqlCommand(sql, con3))
            {
                con3.Open();

                command.Parameters.AddWithValue("@title", title);
                command.Parameters.AddWithValue("@body", body);
                command.Parameters.AddWithValue("@postid",  Request.QueryString["edit"].ToString());

                command.ExecuteNonQuery();
                con3.Close();
                message = "its ok.";
                lbl_result.Text = message;
            }
        }
   }
}

在userView之后将userNewPasswor作为字符串传递给控制器并将其传递给UserManager
```
  <input type="password" id= "userNewPassword" name="userNewPassword">
```

注意：最好的方法是修改userView并将userNewPassword添加到模型中

更新

在visual studio 2013中如果您使用了asp.net默认模板，您将找到流动的类

  [HttpPost]
  public ActionResult ChangePassword(
            AspNetUsersViewModel userView,
            string userNewPassword){

                       UserManager<IdentityUser> userManager = new UserManager<IdentityUser>(new UserStore<IdentityUser>());
                       var result = userManager.ChangePassword(_User.Id, userNewPassword , userView.Password);
                       return RedirectToAction("Index", "ConfigUser");


                                 }

使用UserManager从用户获取密码
