Question

运行代码时出现以下错误：

System.Configuration.ConfigurationErrorsException：'配置部分不能包含CDATA或文本元素'

应用程序构建得很好但是当我选择链接转到应用程序中的“about”视图时，它会抛出上面的错误。

这是代码中突出显示的行：

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

这是web.config文件中的连接字符串：

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

如果需要更多，请告诉我，我可以发布您需要的任何内容

这是整个网络配置文件

<?xml version="1.0" encoding="utf-8"?>

简短解决方案：删除标记之间的空格。

如果我复制你的配置包含一个渲染为空格但实际上不是的字符。对于配置解析器，除了空格和制表符之外的任何内容都是文本。配置文件中不允许使用文本。

// 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

尝试将配置更改为：

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

在重新添加空格并输入

之前

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

web.config和CDATA出错
