Question

我有一个Web表单asp.net，用于将特定信息保存到Visual Studio中的本地数据库中。这些Web表单组件中的一些是html组件。点击＆＃34;添加＆＃34;按钮，这是作为asp.net按钮，数据成功保存到数据库中，但当我查看我的数据库表时，它显示我＆＃34; System.Web.UI.HtmlControls.HtmlInputText＆＃34;在某些领域，如下图所示：

让我感到困惑的是，我不知道为什么某些值会正确保存而其他值不能保存！ eventName，EventDuration，EventAdmission，EventWebsite和EventVenue都是html文本框..并且如上图所示，对于所有这些字段，保存的值是＆＃34; System.Web.UI.HtmlControls.HtmlInputText＆＃34;而EventVenue值正确保存!!即使代码相同..请参阅下面的示例：

<div class="6u$ 12u$(small)">
                                                <label for="website">Website</label>
                                                <input type="text" id="website" name="website" runat="server" />

                                            </div>

                                            <div class="6u$ 12u$(small)">
                                                <label for="venue">Venue</label>
                                                <input type="text" id="venue" name="venue" runat="server" />

这是我的源代码：

 protected void addbtn_Click(object sender, EventArgs e)
    {
        string latitude = "";
        string longitude = "";
        string imagesArr = null;
        bool fields = false;
        string eventname = Request.Form["name"].ToString();
        string disc = Request.Form["TextArea3"].ToString();

        string startDate = DropDownList1.Text + "/" + category.Value + "/" + DropDownList2.Text;
        string endDate = DropDownList4.Text + "/" + days.Value + "/" + DropDownList5.Text;

        string eventduration = Request.Form["duration"].ToString()
        string eventadmission = admission.Value;
        string categ = DropDownList3.Text;
        string contact = Request.Form["TextArea4"].ToString();
        string eventwebsite = website.Value;
        string location = venue.Value;
        country.Disabled = true;
        string eventcountry = Request.Form["country"].ToString();


        if (Session["Latitude"].ToString() == null && Session["Longitude"].ToString() == null)
        {
            latitude = "";
            longitude = "";
        }
        else if (Session["Latitude"].ToString() != null && Session["Longitude"].ToString() != null)
        {
            latitude = Session["Latitude"].ToString();
            longitude = Session["Longitude"].ToString();
        }

        if (Session["ImagesArray"].ToString() != null)
        {
            imagesArr = Session["ImagesArray"].ToString();
        }



        if (DropDownList2.Text.Equals("Year") || DropDownList1.Text.Equals("Month") || category.Value.Equals("Day") || DropDownList5.Text.Equals("Year") || DropDownList4.Text.Equals("Month") || days.Value.Equals("Day") || name == null || disc == null || duration == null || admission == null || categ == null || contact == null || website == null || location == null)
        {
            fields = true;
            ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alertMessage", "alert(' Make sure to enter all the required data')", true);
        }
        else { fields = false; }

        if (fields == false)
        {
            command.CommandText = "INSERT INTO EventsEnglish(EventName,EventDescription,EventStartDate,EventEndDate,EventDuration, EventAdmission, EventCategory, EventContact, EventWebsite, EventVenue, EventMapLatitude, EventMapLongitude, CountryName, EventImages) values(N'" + name + "', N'" + disc + "',N'" + startDate + "',N'" + endDate + "',N'" + duration + "',N'" + admission + "', N'" + categ + "',  N'" + contact + "',  N'" + website + "',  N'" + location + "',  N'" + latitude + "',  N'" + longitude + "',  N'" + country + "',  N'" + imagesArr + "')";
            //command.ExecuteNonQuery();

            int result = command.ExecuteNonQuery();
            if (result == 1)
            {
                ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alertMessage", "alert(' New event has been added')", true);

                name.Value = "";
                TextArea3.InnerText = "";
                DropDownList1.Text = "Month";
                category.Value = "Day";
                DropDownList2.Text = "Year";
                DropDownList4.Text = "Month";
                days.Value = "Day";
                DropDownList5.Text = "Year";
                duration.Value= "";
                admission.Value = "";
                DropDownList3.Text = "Category";
                TextArea4.InnerText = "";
                website.Value = "";
                venue.Value = "";

                Session.Remove("ImagesArray");
                Session.Remove("Latitude");
                Session.Remove("Longitude");


            }
            con.Close();
        }


    }

如上面的代码所示，我使用了两种不同的方法来获取html文本框值的值，例如＆＃34; Request.Form [＆＃34; name＆＃34;]。的ToString（）;＆＃34;和＆＃34; name.Value;＆＃34;并且没有一个工作，除了第二种方式适用于＆＃34; Venue＆＃34;只有字段。

你有什么想法解决这个问题吗？

好吧，我在这段代码中找出了我的问题

 command.CommandText = 
    "INSERT INTO EventsEnglish( " +
        "EventName, EventDescription, EventStartDate, EventEndDate, " +
        "EventDuration, EventAdmission, EventCategory, EventContact, " +
        "EventWebsite, EventVenue, EventMapLatitude, EventMapLongitude, " +
        "CountryName, EventImages) " +
    "VALUES (" +
        "N'" + name + "', N'" + disc + "', N'" + startDate + "', " +
        "N'" + endDate + "',N'" + duration + "',N'" + admission + "', " +
        "N'" + categ + "',  N'" + contact + "',  N'" + website + "',  " +
        "N'" + location + "',  N'" + latitude + "',  N'" + longitude + "', " +
        "N'" + country + "',  N'" + imagesArr + "')";

我只需要添加string local variables而不是html text框名称..我不知道我怎么没注意到这一点!!

保存System.Web.UI.HtmlControls.HtmlInputText而不是文本框的值asp.net
