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

Question

我有一个Web窗体，asp.net，将特定的信息保存到Visual Studio中的本地数据库中。这些Web表单组件中的一部分是html组件。 点击一个“添加”按钮，这是作为asp.net按钮，数据被成功保存到数据库中，但是当我查看我的数据库表时，它显示我“System.Web.UI.HtmlControls.HtmlInputText”中某些字段如下图所示：

什么让我困惑的是，我不知道为什么有些值是正确保存和别人不！ eventName，EventDuration，EventAdmission，EventWebsite和EventVenue都是html文本框......并且如上图所示，所有这些字段中保存的值是“System.Web.UI.HtmlControls.HtmlInputText”，而EventVenue值正确保存！即使代码相同..见下面的例子：

<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" /> 

这里是我的源代码：

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(); 
     } 


    } 

如上代码所示，我用两种不同的方式获取html文本框值的值，例如“Request.Form [”name“]。ToString（）;”和“name.Value;”除了第二种方法只适用于“Venue”字段外，他们都没有工作。

你有什么想法解决这个问题？

Answer 1

嗯，我想通了，我的问题..在此代码

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 + "')"; 

我不得不添加string local variables代替html text箱名字。我不知道我怎么没注意这个！
