Visual Studio 2022中ASP.NET设计模式Wizard控件渲染错误求助

ASP.NET设计模式中Wizard控件渲染错误问题

我正在学习ASP.NET课程,使用Visual Studio 2022版本。目前在设计模式下遇到异常:每次使用Wizard工具时,都会提示“Error Rendering Control(控件渲染错误)”。

代码本身无问题,浏览器中运行正常,传给同学使用也能正常工作。我试过重装、修复甚至降级Visual Studio,偶尔重装后能恢复,但关闭再打开后问题又会重现。

ASP代码

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication3.WebForm1" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
        <div>
            <asp:Panel ID="Panel1" runat="server">
<asp:Wizard ID="Wizard1" runat="server" ActiveStepIndex="0" OnFinishedButtonClick="Wizard1_FinishButtonClick1" Width="500px" FinishCompleteButtonText="Finish" FinishPreviousButtonText="Back" StartNextButtonText="Next" StepNextButtonText="Next">
<WizardSteps>
<asp:WizardStep ID="WizardStep1" runat="server" Title="About you">
    <asp:Label ID="Label1" runat="server" Text="Name:"></asp:Label>
<asp:TextBox ID="name" runat="server"></asp:TextBox>
</asp:WizardStep>
<asp:WizardStep ID="WizardStep2" runat="server" StepType="Finish" Title="Favorite Language">
        <asp:DropDownList ID="FavoriteLanguage" runat="server">
            <asp:ListItem>C#</asp:ListItem>
            <asp:ListItem>Visual Basic</asp:ListItem>
            <asp:ListItem>CSS</asp:ListItem>
        </asp:DropDownList>
</asp:WizardStep>
<asp:WizardStep runat="server" StepType="Finish" Title="Ready">
<asp:Label ID="resualt" runat="server" Text="Label"></asp:Label>
<br />
</asp:WizardStep>
</WizardSteps>
</asp:Wizard>
</asp:Panel>
        </div>
    </form>
</body>
</html>

C#代码

namespace WebApplication3
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            resualt.Text = "Your Name:" + name.Text;
            resualt.Text += "<br />Your Favorite Language:" + FavoriteLanguage.SelectedValue;
        }
    }
}
