MVC C#显示messagebox.show的应用程序错误 在VisualStudio 2015中运行MVC4应用程序时，她经常运行并在浏览器中运行所有的东西，ULTILIO MeaseBox。在代码中间显示，在一些地方使用相同的，通常不是问题。

我在开发Framework4.6时使用了它，也就是说，我在我的机器上安装了它，这将是服务器强制执行，我的IIS 7和我的UserAppPool只有Framework v4.0.30319

我不需要使用messageBox，但这是我找到的唯一解决方案，是否有其他选项为用户显示消息

在浏览器中打开应用程序时，单击按钮执行操作并生成消息框，它会生成以下错误：

根据目前的评论线索

如果只想将“消息”从控制器发送到视图，可以将其设置为模型上的属性：

someModel.SomeProperty = "Some Message";

或者，在最坏的情况下，作为类似

ViewData

的一部分：

ViewData["SomeProperty"] = "Some Message";

然后，在视图中显示它。理想情况下，这将比

警报（）更优雅。您可以将其包含在标记中：

@if(!string.IsNullOrEmpty(Model.SomeProperty)) {
    <div id="message">@Model.SomeProperty</div>
}

（将JavaScript代码放入Razor块时，您可能需要明智地使用
标记。有时语法会混淆呈现引擎。）
asp.net应用程序中不能有MessageBox如果您不理解问题，无法读取错误，并且您正试图在web应用程序中使用
MessageBox
。这里没有任何意义，对不起。@stuartd不，我不需要使用messageBox，但这是我找到的唯一解决方案，您有其他选项为用户显示消息吗？@David不，我不需要使用messageBox，但这是我找到的唯一解决方案，您还有其他选项可以向用户显示消息吗？@JhonnyPamponet:您必须显示您尝试过的内容，并解释它是如何无法按预期工作的。目前我给你的唯一建议是从一些关于web开发和ASP.NET MVC的入门教程开始
enviar

@if（！string.IsNullOrEmpty（Model.SomeProperty））{alert（'@Model.SomeProperty'）；}但显示错误消息System.Core.dll中发生了“Microsoft.CSharp.RuntimeBinder.RuntimeBinderException”类型的异常，但未在用户代码中处理其他信息：Nãoépossível fazer associaço em tempo de execuço em uma referenceêncianula@JhonnyPamponet：嗯，您的模型是否有名为
SomeProperty
的属性？（或者随便你怎么称呼它。）另外，我看不懂那个错误信息，所以我只能猜测它说了什么。看起来您使用的
标记不正确，尽管我无法通过查看确定。
@if(!string.IsNullOrEmpty(Model.SomeProperty)) {
    <div id="message">@Model.SomeProperty</div>
}

@if(!string.IsNullOrEmpty(Model.SomeProperty)) {
    <script type="text/javascript">
        alert('@Model.SomeProperty');
    </script>
}
