誤差的web.config和CDATA

Question

我收到以下錯誤，當我運行代碼：

System.Configuration.ConfigurationErrorsException：「配置節不能包含CDATA或文本元素」

應用程序構建得很好，但是當我選擇鏈接轉到應用程序中的「關於」視圖時，它會引發上述錯誤。

這是它突出的代碼行：

string conn = ConfigurationManager.ConnectionStrings["CountryConnectionString"].ConnectionString; 

，這是在web.config文件中的連接字符串：

<add name="CountryConnectionString" connectionString="Data Source=localhost;Integrated Security=SSPI;Initial Catalog=TestData" providerName="System.Data.SqlClient" />  

如果更多的是讓我知道和需要我可以發表任何你需要的東西

這裏是整個網頁配置文件

Answer 1

簡短解決方案：刪除標籤之間的空格。

如果我複製你的配置包含一個呈現爲空白但實際上不是的字符。除了空格和製表符之外，配置解析器都是文本。文本在配置文件中是不允許的。

// the spacing character 
Encoding.UTF8.GetBytes(new[] { ' ' })[0] // yields 194 
Encoding.UTF8.GetBytes(new[] { ' ' })[1] // yields 160 

// the actual space 
Encoding.UTF8.GetBytes(new[] { ' ' })[0] // yields 32 

嘗試將配置更改爲：

<connectionStrings><add name="CountryConnectionString" connectionString="Data Source=localhost;Integrated Security=SSPI;Initial Catalog=TestData" providerName="System.Data.SqlClient" /></connectionStrings> 

重新添加空格之前和進入

<connectionStrings> 
    <add name="CountryConnectionString" connectionString="Data Source=localhost;Integrated Security=SSPI;Initial Catalog=TestData" providerName="System.Data.SqlClient" /> 
</connectionStrings>
