这篇文章主要为大家详细介绍了MVC使用T4模板生成其他类的具体实现,具有一定的参考价值，感兴趣的小伙伴们可以参考一下
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。
狼蚁网站SEO优化是数据访问层的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，狼蚁网站SEO优化我将提供相应的代码
