我正在尝试使用EntLib将connectionStrings移动到外部文件,但
ConfigurationManager.ConnectionStrings
只给我默认的ASP.NET数据库,甚至在配置中也没有。
data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true
我希望看到shared.config中有两个连接字符串。 可能是什么问题,或者我对此功能的理解有误?
的App.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="enterpriseLibrary.ConfigurationSource" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ConfigurationSourceSection, Microsoft.Practices.EnterpriseLibrary.Common, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
</configSections>
<enterpriseLibrary.ConfigurationSource selectedSource="System Configuration Source">
<sources>
<add name="System Configuration Source" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.SystemConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
<add name="Shared" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
filePath="shared.config" />
</sources>
<redirectSections>
<add sourceName="Shared" name="connectionStrings" />
</redirectSections>
</enterpriseLibrary.ConfigurationSource>
</configuration>
shared.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<connectionStrings>
<add name="connStr1" connectionString="Data Source=local;Initial Catalog=DB1;Integrated Security=True"
providerName="System.Data.SqlClient" />
<add name="connStr2" connectionString="Data Source=local;Initial Catalog=DB2;Integrated Security=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>

实际上,ConfigurationManager.ConnectionStrings
对企业库基础架构一无所知。
默认情况下,无法使用Enterprise Library的ConfigurationSource重定向节。
您应该使用configSource
属性,这是.NET Framework的功能,而不是Enterprise Library。
的app.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<connectionStrings configSource="sharedConnectionStrings.config" />
</configuration>
sharedConnectionStrings.config:
<?xml version="1.0" encoding="utf-8" ?>
<connectionsStrings>
<add name="connStr1"
connectionString="Data Source=local;Initial Catalog=DB1;Integrated Security=True"
providerName="System.Data.SqlClient" />
<add name="connStr2"
connectionString="Data Source=local;Initial Catalog=DB2;Integrated Security=True"
providerName="System.Data.SqlClient" />
</connectionsStrings>
更新:如果您要使用Enterprise Library功能,请不要直接使用ConfigurationManager.ConnectionStrings
。而是使用Enterprise Library功能创建数据库连接,如:
Database db = DatabaseFactory.CreateDatabase(“Tom’s Connection”);
然后您可以使用Enterprise Library的配置源。
我发现这个link with example很有用。
