這篇文章主要介紹了MVC如何使用T4模板生成其他類，具有一定借鑒價值，感興趣的朋友可以參考下，希望大家閱讀完這篇文章之后大有收獲，下面讓小編帶著大家一起了解一下。
在前篇中我們已經將User類中的代碼做了具體的實現，但仍然有多個實體類未實現，以后可能還會增加新的數據表，數據表結構也有可能發生變化，所以我們使用T4模板來完成類的生成，這樣就算數據庫表發生了改變，也會自動根據改變后的實體對類進行重新生成。
下面是數據訪問層的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實體文件在項目中的路徑
string inputFile = @"..\\PMS.Model\\PMS.edmx";
EdmItemCollection ItemCollection = loader.CreateEdmItemCollection(inputFile);
string namespaceName = code.VsNamespaceSuggestion();
EntityFrameworkTemplateFileManager fileManager = EntityFrameworkTemplateFileManager.Create(this);
#>
<#//這里為命名空間部分，手動更改為相應的命名空間 #>
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
{
}
<#}#>
}我們將EF實體文件路徑、命名空間更改為對應的值時，Ctrl+S保存，即可生成對應的其他類型的數據訪問類
其他層中也大同小異，只需要做對應的更改即可，下面我將提供相應的代碼
IDAL層

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