运行ASP.NET C＃应用程序的问题 [英] Problem running ASP.NET C# application

问题描述

我正在阅读乞求ASP.NET for Visual Studio 2015.他们的论坛已经死了，没有任何帮助，我不知道如何研究这个问题，因为我以前从未遇到过它。

我一直在构建练习应用程序，本书引导我完成并且从未遇到过运行我的应用程序的问题，但是在我完成最后一次练习之后，当我尝试运行我的应用程序我得到错误服务器错误'/'应用程序



我的浏览器中的消息如下：

Im reading Begging ASP.NET For Visual Studio 2015. Their forum is dead and of no help and I`m not sure how to even research this problem because Ive never come across it before.
I`ve been building the practice application that the book walk me through and have never had a problem running my application, however after I finished the last exercise following everything to the "t" when I try to run my app I get and error "Server Error In '/' Application

The message in my browser is as follows:

Server Error in '/' Application.

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. 

Parser Error Message: Unable to connect to any of the specified MySQL hosts.

正如我所说，这是第一次我有这个错误的时间，不知道如何搜索这个。背后的所有代码都是C＃



我尝试过：



我不知道该尝试什么？它是一个sql错误但它以前一直有效。当我运行这个应用程序时，我没有改变它引用的页面中的任何内容和visual studio没有错误或警告

As I`ve said this is the first time I have had this error and have no idea how to even search this. All the code behind is C#

What I have tried:

I don`t know what to try? Its an sql error but it has always worked before. I havent altered anything in the page its referring to and visual studio has no errors or warnings when I run this application

推荐答案

当我在学习从ASP.NET 4.5.1开始：在C＃和VB 中。幸运的是，用户 zinedu5 发布了一个对我有用的解决方案，可以在这里找到：



第7章：配置错误 [ ^ ]



您必须将以下代码添加到web.config文件中：

The same problem occurred when I was studying Beginning ASP.NET 4.5.1 : in C# and VB. Fortunately, user zinedu5 posted a solution that worked for me, that can be found here:

Chapter 7: Configuration Error[^]

You have to add the following code to the web.config file :

<system.web>
 ...
  <siteMap>
    <providers>   
        <remove name="MySqlSiteMapProvider" />
    </providers>
  </siteMap>
</system.web>

希望这对您也有用！

Hope this works for you as well!

查看错误消息：

Look at the error message:

Unable to connect to any of the specified MySQL hosts.

它可能不是很清楚 - 你正在尝试连接到MySql不存在的服务器。

猜测，你没有改变示例代码来解决你的实际安装 - 你不能指望这个例子（必须是每个读取的人）这本书）提前知道你的具体连接和登录详情是什么！

It couldn't be a lot clearer - you are trying to connect to a MySql server which doesn't exist.
At a guess, you haven't alters the example code to address your actual installation - and you can't expect the example (which has to be for everyone who reads the book) to know in advance what your specific connection and login details are!

谢谢。你做了我的一天..从2天开始苦苦挣扎..

我使用sqlserver而错误报告与MySQL有关。
