ASP.. NET上的Mono 4.0 -对象未找到
本文关键字：对象 NET 上的 Mono ASP | 更新日期: 2023-09-27 17:51:07
我对ASP相当陌生。. NET和我在*中获得ASP对象的id有问题。由继承该页的c#文件(关联的*.aspx.cs文件)检测。
对于某些上下文中，我的任务是迁移ASP。使用Mono从Windows Server 2008 R2实例上的IIS服务器到CentOS。NET网站。该应用程序在Windows 8.1上使用VS 2012构建并成功运行。
我能够将应用程序移植到Linux上，但在MonoDevelop中构建和运行应用程序时遇到了问题。我正在开发CentOS 7与Mono 4.0和MonoDevelop 5.9与应用程序是一个asp.net应用程序(不是一个asp.net MVC应用程序)。
在将项目文件和程序集加载到原生MonoDevelop ASP . net应用程序项目中并登台之后，我收到了以下错误，因为在*.aspx.cs文件中引用的几个对象变量id，但在*. js文件中声明。aspx文件。下面是其中一个页面(登录页面)的示例:
<我> login.aspx.cs :
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class ILSecure_login : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void LoginButton_Click(object sender, EventArgs e)
{
if (FormsAuthentication.Authenticate(this.UserName.Text.Trim(), this.Password.Text.Trim()))
{
FormsAuthentication.RedirectFromLoginPage(this.UserName.Text.Trim(), false);
}
else
{
this.FailureText.Text = "Incorrect username or password.<br><b>Please re-enter your credentials.</b>";
}
}
}
<我>登录。Aspx (重要部分):
<table border="0" cellpadding="1" cellspacing="0" style="border-collapse: collapse">
...
<tr>
<td align="right" bgcolor="#f5f8fb">
<asp:Label ID="UserNameLabel" runat="server" AssociatedControlID="UserName">User Name:</asp:Label></td>
<td bgcolor="#f5f8fb" style="width: 168px">
<asp:TextBox ID="UserName" runat="server" BorderStyle="Solid"></asp:TextBox>
<asp:RequiredFieldValidator ID="UserNameRequired" runat="server" ControlToValidate="UserName"
ErrorMessage="User Name is required." ToolTip="User Name is required." ValidationGroup="Login1">*</asp:RequiredFieldValidator> </td>
</tr>
...
<tr>
<td align="right" bgcolor="#f5f8fb">
<asp:Label ID="PasswordLabel" runat="server" AssociatedControlID="Password">Password:</asp:Label></td>
<td bgcolor="#f5f8fb" style="width: 168px">
<asp:TextBox ID="Password" runat="server" TextMode="Password" BorderStyle="Solid"></asp:TextBox>
<asp:RequiredFieldValidator ID="PasswordRequired" runat="server" ControlToValidate="Password"
ErrorMessage="Password is required." ToolTip="Password is required." ValidationGroup="Login1">*</asp:RequiredFieldValidator> </td>
</tr>
...
<tr>
<td colspan="2" align="center" bgcolor="#f5f8fb" style="color: red">
<asp:Literal ID="FailureText" runat="server" EnableViewState="False"></asp:Literal></td>
</tr>
<tr>
<td colspan="2" align="center" valign="middle" bgcolor="#ebf1f7" style="height: 32px">
<asp:Button ID="LoginButton" runat="server" CommandName="Login" OnClick="LoginButton_Click"
Text="Log In" ValidationGroup="Login1" BackColor="#E0E0E0" ForeColor="Black" BorderStyle="Solid" /></td>
</tr>

EDIT根据@Misters (https://stackoverflow.com/users/1874460/misters)请求添加
MonoDevelop环境错误(不幸的是，我没有足够的Rep来发布图像):
/root/intellilock/intellilock/licensemanagement/login.aspx.cs(40,40): Error CS0103: The name `UserName' does not exist in the current context (CS0103) (intellilock)
/root/intellilock/intellilock/licensemanagement/login.aspx.cs(62,62): Error CS0103: The name `Password' does not exist in the current context (CS0103) (intellilock)

/root/intellilock/intellilock/licensemanagement/login.aspx.cs(14,14): Error CS0103: The name `FailureText' does not exist in the current context (CS0103) (intellilock)
我的想法是在*.aspx.cs代码中添加占位符变量以使其构建，这对构建过程有效:
protected System.Web.UI.WebControls.Label UserName;
protected System.Web.UI.WebControls.Label Password;
protected System.Web.UI.WebControls.Literal FailureText;
但是，在运行时，我收到了以下错误:

是否有一个更好的方法，我应该用它来获得ASP对象变量id由c#脚本检测?
谢谢Matt!(https://stackoverflow.com/users/268874/matt-ward)我从旧*复制的代码。将*aspx和*aspx.cs文件放入一个新的"Web Form with Code Behind"文件中，该文件的名称和位置与原始文件相同。在构建时，*.aspx.designer.cs文件由Mono 4.0运行时自动生成，并且可以正确构建。
再次感谢所有的帮助!
