尝试配置企业库5.0（数据访问应用程序块）时出现问题 [英] Problem when trying to configure enterprise library 5.0 (Data Access Application Block)

问题描述

尝试从企业库5.0运行DAAB时遇到一些问题。我已经按照教程中的步骤进行操作，但是却出现了错误...

I am running into some problems while trying to get DAAB from Enterprise library 5.0 running. I have followed the steps as per the tutorial, but am getting errors...

1）下载/安装企业库

1) Download / install enterprise library

2）添加对我需要的块的引用（公共/数据）

2) Add references to the blocks I need (common / data)

3）导入

Imports Microsoft.Practices.EnterpriseLibrary.Common
Imports Microsoft.Practices.EnterpriseLibrary.Data

4）通过企业库配置软件。我从站点打开web.config。然后，我单击块，然后单击添加数据设置...，填写我的详细信息并保存/关闭

4) Through the enterprise library config software. I open up the web.config from my site. I then click Blocks, then Add data settings... fill in my details and save / close

5）然后，我（认为安装已完成）尝试获取实例通过

5) I then (thinking setup is complete) try to get an instance of the database via

 Dim db As Database = DatabaseFactory.CreateDatabase() 

6）我编译并收到以下错误：

6) I compile and receive the following error:

无法加载文件或程序集'Microsoft .Practices.EnterpriseLibrary.Data，版本= 5.0.414.0，文化=中性，PublicKeyToken = 31bf3856ad364e35'或其依赖项之一。找到的程序集的清单定义与程序集引用不匹配。 （来自HRESULT的异常：0x80131040）（C：\site\web.config第4行）

Could not load file or assembly 'Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) (C:\site\web.config line 4)

我的web.config的第4行是由配置工具生成的，是：

Line 4 off my web.config was generated by the config tool and is:

<section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />

我错过了必需的步骤吗？我是否以错误的顺序完成了步骤？我犯错了吗？

Am I missing a required step? Have I done the steps in the wrong order? Have I made a mistake?

非常感谢您的帮助。

推荐答案

答案：

我不小心引用了src代码文件夹中的程序集。这意味着公共令牌将具有= null。我重新引用了C：\Program Files\Microsoft Enterprise Library 5.0\Bin中的程序集，该问题现在已解决。

I had accidentaly referenced the assemblies from the src code folder. Which means the public tokens would have = null. I re-referenced to the assemblies in C:\Program Files\Microsoft Enterprise Library 5.0\Bin and the problem is now solved.
