System.Configuration.ConfigurationErrorsException

我有一個有幾個文本框的表單，您可以在文本框中輸入一些值，然後當您按下提交時將值保存到文件中。但是，當我按下提交時，我得到以下異常。System.Configuration.ConfigurationErrorsException

System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---> System.Configuration.ConfigurationErrorsException: Unrecognized configuration section add. (C:\Program Files (x86)\Default Company Name\Setup\HomeInventory2.exe.Config line 3)

如果我正確讀取它，問題出在我的App.config文件中。但我在該文件中沒有看到任何問題 - 如下所示。

<?xml version="1.0" encoding="utf-8" ?> 
<configuration> 
    <add key="InventorySvc" value="HomeInventory2.Services.InventorySvc" /> 
</configuration>

的<add key應該像裏面有<appSettings>沒有配置 - >添加。它應該像配置 - > appsettings->添加。

您的配置文件應該是這樣的：

<?xml version="1.0" encoding="utf-8" ?> 
<configuration> 
    <appSettings> 
    <add key="InventorySvc" value="HomeInventory2.Services.InventorySvc"/> 
    </appSettings> 
</configuration>

appSettings - 預定義的構成部分之一，.NET
