Microsoft Enterprise Library 5.0 如何集成MySQL数据库

今天在网上找了一下Microsoft Enterprise Library 5.0 如何集成MySQL数据库， 结果只找到了entlib 4.1的扩展模块，

http://entlibcontrib.codeplex.com/ ， 按照上面的说明配制后还是不成功。

于是只好手动修改一下来支持entlib 5.0

修改后的项目：   MySqlDAAB.rar 

MySql.Data.dll:  MySql.Data.dll

1. 修改MySqlDatabaseAssembler.cs文件

public   class  MySqlDatabaseData : DatabaseData
    {
         #region  Public Methods
         public  MySqlDatabaseData(ConnectionStringSettings connectionStringSettings, IConfigurationSource configurationSource)
            :  base (connectionStringSettings, configurationSource)
        {
        }
         #endregion

         public   override  System.Collections.Generic.IEnumerable < Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ContainerModel.TypeRegistration >  GetRegistrations()
        {
             yield   return   new  TypeRegistration < Database > (
                ()  =>   new  MySqlDatabase(
                    ConnectionString,
                    Container.Resolved < IDataInstrumentationProvider > (Name))) {
                        Name  =  Name,
                        Lifetime  =  TypeRegistrationLifetime.Transient
                    };
        }
    }

2. 修改MySqlDatabase.cs文件中的构造函数和在MySqlDatabase类上加上配制属性

　　[ConfigurationElementType( typeof (MySqlDatabaseData))]
     public   class  MySqlDatabase : Database
    {       
         public  MySqlDatabase( string  connectionString)
            :  base (connectionString, MySqlClientFactory.Instance)
        {
        }        
         public  MySqlDatabase( string  connectionString, IDataInstrumentationProvider instrumentationProvider)
            :  base (connectionString, MySqlClientFactory.Instance, instrumentationProvider)
        {
        }        

3. 编译MySqlDAAB项目

4. 在项目中引用MySqlDAAB项目

5. 配制文件中如下配制： 

     < configSections >
         < section name = " dataConfiguration "
            type = " Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings,
                    Microsoft.Practices.EnterpriseLibrary.Data "  />
     </ configSections >
     < dataConfiguration  >
         < providerMappings >
             < add name = " MySql.Data.MySqlClient "
            databaseType = " EntLibContrib.Data.MySql.MySqlDatabase, MySqlDAAB "   />
         </ providerMappings >
     </ dataConfiguration >
     < system.data >
         < DbProviderFactories >
             < add
                name = " My Sql Data Provider Factory "
                invariant = " MySql.Data.MySqlClient "
                description = " "
                type = " MySql.Data.MySqlClient.MySqlClientFactory "   />
         </ DbProviderFactories >
     </ system.data >
     < connectionStrings >
    　　 < add name = " TestDB_MySql "  

　　　　　　connectionString = " server=127.0.0.1;database=test;User Id=root;Password=****;Persist Security Info=True; "
           providerName = " MySql.Data.MySqlClient " />
     </ connectionStrings >

 这样就可以使用MySQL数据库了。
