我有2个项目:Console app和dll。在DLL中我使用EntityFramework。我有这个app.config文件:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
<providers>
<provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>
</entityFramework>
<connectionStrings>
<add name="NorthwindConnection" connectionString="Data Source=ВЛАДИСЛАВ-ПК\SQLEXPRESS;Initial Catalog=Northwind;User ID=sa;Password=sa;" providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>
我从控制台应用程序调用EntityFramework,但是我有这样的错误消息:“在应用程序配置文件中找不到名为”NorthwindConnection“的连接字符串。”。
这是控制台app.config文件:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
</configuration>
答案 0 :(得分:1)
将.dll配置文件中的以下标记复制到控制台项目app.config
:
<connectionStrings>
<add name="NorthwindConnection" connectionString="Data Source=ВЛАДИСЛАВ-ПК\SQLEXPRESS;Initial Catalog=Northwind;User ID=sa;Password=sa;" providerName="System.Data.SqlClient" />
</connectionStrings>
所以你的控制台项目中的app.config
将是:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<connectionStrings>
<add name="NorthwindConnection" connectionString="Data Source=ВЛАДИСЛАВ-ПК\SQLEXPRESS;Initial Catalog=Northwind;User ID=sa;Password=sa;" providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>
