Firebird 嵌入式服务器未在 ASP.NET MVC 3 项目中加载（无法加载 DLL“fbembed”）

发布于 2024-12-05 18:09:20 字数 2173 浏览 3 评论 0原文

在 ASP.NET MVC 项目（使用 Entity Framework 4.1 代码优先方法）中，我添加了对 C:\Program Files\FirebirdClient\FirebirdSql.Data.FirebirdClient.dll 的引用。

Web.config 中的配置如下所示：

<system.data>
    <DbProviderFactories>
      <remove invariant="FirebirdSql.Data.FirebirdClient"/>
      <add
          name="Firebird Data Provider"
          invariant="FirebirdSql.Data.FirebirdClient" description="Firebird"
          type="FirebirdSql.Data.FirebirdClient.FirebirdClientFactory, FirebirdSql.Data.FirebirdClient, Version=2.6.5.0, Culture=neutral, PublicKeyToken=3750abcc3150b00c"          
      />
    </DbProviderFactories>
  </system.data>

连接字符串如下所示（数据库不存在，应从实体框架生成）：

<add name="AdvertiserDatabase"
      connectionString="ServerType=1;User=SYSDBA;Password=masterkey;Dialect=3;Database=|DataDirectory|AdvertiserDb.fdb"
      providerName="FirebirdSql.Data.FirebirdClient"/>

将所有需要的文件（firebird.msg、icu*30.dll）添加到 bin 文件夹，还添加了文件夹 intl 和 udf。

将 fbembed.dll 重命名为 fbclient.dll。

在运行时我收到以下错误：无法加载 DLL“fbembed”：找不到指定的模块。（HRESULT 异常：0x8007007E）

出了什么问题？这应该有效！

提前致谢

编辑在输出窗口中，我注意到以下消息（这让我很困惑）：

原文

In an ASP.NET MVC project (using Entity Framework 4.1 code first approach) i added a reference to C:\Program Files\FirebirdClient\FirebirdSql.Data.FirebirdClient.dll.

The configuration in Web.config looks as follows:

<system.data>
    <DbProviderFactories>
      <remove invariant="FirebirdSql.Data.FirebirdClient"/>
      <add
          name="Firebird Data Provider"
          invariant="FirebirdSql.Data.FirebirdClient" description="Firebird"
          type="FirebirdSql.Data.FirebirdClient.FirebirdClientFactory, FirebirdSql.Data.FirebirdClient, Version=2.6.5.0, Culture=neutral, PublicKeyToken=3750abcc3150b00c"          
      />
    </DbProviderFactories>
  </system.data>

The connection string looks like this (database is non existend, should be generated from Entity Framework):

<add name="AdvertiserDatabase"
      connectionString="ServerType=1;User=SYSDBA;Password=masterkey;Dialect=3;Database=|DataDirectory|AdvertiserDb.fdb"
      providerName="FirebirdSql.Data.FirebirdClient"/>

Added all the needed files (firebird.msg, icu*30.dll) to the bin folder, added also the folders intl and udf.

Renamed the fbembed.dll to fbclient.dll.

At runtime i get the following error:
Unable to load DLL 'fbembed': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

What is going wrong? This should work!

Thanks in advance

EDIT
In the output window i noticed the following messages (which confuses me a lot):

您不应将 fbembed.dll 重命名为 fbclient.dll。但您也可以在连接字符串中使用 ClientLibrary（检查 FbConnectionStringBuilder 类）参数来指定名称（和路径）。

使用“ClientLibrary”示例在连接字符串中定义 fbembed.dll 的路径

：

<add name="myconn" connectionString="User=SYSDBA;Password=masterkey;Dialect=3;Database=|DataDirectory|mydatafile.fdb;ServerType=1;ClientLibrary=AbsolutePathToDll\fbembed.dll" />

Define the Path to your fbembed.dll in your connectionstring with "ClientLibrary"

Sample:

<add name="myconn" connectionString="User=SYSDBA;Password=masterkey;Dialect=3;Database=|DataDirectory|mydatafile.fdb;ServerType=1;ClientLibrary=AbsolutePathToDll\fbembed.dll" />
