想了解MVC使用T4模板生成其他类的具体实现学习笔记2的相关内容吗,叫我玮仔在本文为您仔细讲解MVC使用T4模板生成其他类的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:MVC使用T4模板生成其他类,T4模板生成其他类,下面大家一起来学习吧。

在前篇中我们已经将User类中的代码做了具体的实现,但仍然有多个实体类未实现,以后可能还会增加新的数据表,数据表结构也有可能发生变化,所以我们使用T4模板来完成类的生成,这样就算数据库表发生了改变,也会自动根据改变后的实体对类进行重新生成。

下面是数据访问层的T4模板文件 Dal.tt

<#@ template language="C#" debug="false" hostspecific="true"#>
<#@ include file="EF.Utility.CS.ttinclude"#><#@
 output extension=".cs"#>
 
<#

CodeGenerationTools code = new CodeGenerationTools(this);
MetadataLoader loader = new MetadataLoader(this);
CodeRegion region = new CodeRegion(this, 1);
MetadataTools ef = new MetadataTools(this);

//EF实体文件在项目中的路径
string inputFile = @"..\\PMS.Model\\PMS.edmx";

EdmItemCollection ItemCollection = loader.CreateEdmItemCollection(inputFile);
string namespaceName = code.VsNamespaceSuggestion();

EntityFrameworkTemplateFileManager fileManager = EntityFrameworkTemplateFileManager.Create(this);

#>
<#//这里为命名空间部分,手动更改为相应的命名空间 #>
using PMS.IDAL;
using PMS.Model;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace PMS.DAL
{
<#
// Emit Entity Types

foreach (EntityType entity in ItemCollection.GetItems<EntityType>().OrderBy(e => e.Name))
{
  //fileManager.StartNewFile(entity.Name + "RepositoryExt.cs");
  //BeginNamespace(namespaceName, code);  
#>    
  public partial class <#=entity.Name#>Dal :BaseDal<<#=entity.Name#>>,I<#=entity.Name#>Dal
  {

  }
<#}#>
  
}

我们将EF实体文件路径、命名空间更改为对应的值时,Ctrl+S保存,即可生成对应的其他类型的数据访问类

其他层中也大同小异,只需要做对应的更改即可,下面我将提供相应的代码

IDAL层
