System.Configuration.ConfigurationErrorsException
提问by Expecto
I have a form that has a few text boxes, you input some values into the text boxes and then when you press submit it saves the values to a file. However when I press submit, I get the following exception.
我有一个有几个文本框的表单，你在文本框中输入一些值，然后当你按下提交时，它会将值保存到一个文件中。但是，当我按下提交时，出现以下异常。

If I am reading it correctly, the problem is in my App.config file. But I don't see any problem in that file - which is as follows.
如果我没看错，问题出在我的 App.config 文件中。但是我在该文件中没有看到任何问题 - 如下所示。
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<add key="InventorySvc" value="HomeInventory2.Services.InventorySvc" />
</configuration>

The <add keyshould be inside like <appSettings>There is no configuration->add. It should be like configuration->appsettings->add.
本<add key应该是里面好像<appSettings>没有配置- >添加。它应该像配置->应用设置->添加。

Your configuration file should look like this:
您的配置文件应如下所示：
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="InventorySvc" value="HomeInventory2.Services.InventorySvc"/>
</appSettings>
</configuration>
appSettings- one of predefined configuration sections in .NET
appSettings- .NET 中预定义的配置部分之一
