C# 如何使用edmgen.exe生成.edmx.diagram文件?

C# 如何使用edmgen.exe生成.edmx.diagram文件?,c#,asp.net-mvc,entity-framework,entity-framework-6,edmx-designer,C#,Asp.net Mvc,Entity Framework,Entity Framework 6,Edmx Designer,使用中提供的建议,我能够生成ASP.net项目所需的EDMX文件。使用如下命令: "%windir%\Microsoft.NET\Framework\v4.0.30319\edmgen.exe" /mode:fullgeneration /c:"Data Source=%datasourceserver%; Initial Catalog=School; Integrated Security=SSPI" /project:School /entitycontainer:School

使用中提供的建议,我能够生成ASP.net项目所需的EDMX文件。使用如下命令:

"%windir%\Microsoft.NET\Framework\v4.0.30319\edmgen.exe" /mode:fullgeneration    /c:"Data Source=%datasourceserver%; Initial Catalog=School; Integrated Security=SSPI"    /project:School /entitycontainer:SchoolEntities /namespace:SchoolModel /language:CSharp
但是,如果我们通过ADO.Net数据模型在现有项目之外创建edmx,我不知道如何生成在Visual Studio中生成的附带的edmx.diagram文件

在解决方案资源管理器中,可以在如下位置查看文件:

也可以在Visual studio中打开该文件,以UML图的形式查看数据库结构,如下所示:

此外,为此生成的文件如下所示:

我阅读了有关如何使用edmgen.exe生成edmx文件的文档,以及来自官方的文档

我相信Microsoft文档中缺少生成edmx.document文件的文档,我自己无法想出解决方案。我在这个问题上已经被困了很长时间,需要帮助解决这个问题

我使用了类似的机制来生成convertor项目所需的文件。拥有这一能力可以大有帮助。请帮帮我

编辑1: 我注意到edmx.diagram文件具有这样的属性。我不确定的是,VisualStudio是否在内部使用其他一些可执行文件来生成图表文件,或者是否存在可以通过命令行创建图表文件的未记录标志。请原谅我的编辑此信息在最初发布问题时不可用

编辑2: 我使用的流程中涉及的所有步骤:

步骤1:将我的文件复制到需要生成edmx和依赖项文件的文件夹中

注意:这些文件是虚拟文件,将由我在问题中粘贴的命令行命令生成

步骤2:通过导航到同一路径来运行命令行命令

步骤3:运行命令行后,从用户收集的连接字符串将帮助在同一目录中生成必要的CSDL、SSDL和MSL文件。然后,这些文件将被读取并替换到edmx文件中,我已将这些文件包含在上面链接的resources文件夹中

步骤4:运行textTransform.bat文件,从textTransform.exe的Windows SDK路径运行textTransform.exe

观察: 在此阶段,将创建6个文件中的5个,即:

  • .context.tt
  • .context.cs
  • .Designer.cs
  • .tt
  • .cs
  • 对应于用户提供的名称

    但是缺少文件.edmx.diagram
