asp.net mvc项目自定义区域

前言

直接上干货就是，就不废话了。
使用场景：分离模块，多站点等~~

一、分离模块

自定义视图引擎，设置视图路径格式
项目结构图

1.Code: 在Global.asax Application_Start方法中添加自定义的视图引擎

        using System.Collections.Generic;
        using System.Web.Mvc;
        namespace MvcProjectMain.AreasViewEngine
        {

            /// <summary>       
            /// 自定义视图引擎
            /// </summary>
            /// <remarks>
            ///  ViewEngines.Engines.Add(new MvcProjectMain.AreasViewEngine.ThemableRazorViewEngine());
            /// </remarks>
            public class ThemableRazorViewEngine : VirtualPathProviderViewEngine
            {
                //所有区域分离到Modules文件夹,{2}为区域名
                public ThemableRazorViewEngine()
                {
                    ViewEngines.Engines.Clear();
                    AreaViewLocationFormats = new[]
                    {
                    "~/Modules/{2}/Views/{1}/{0}.cshtml", 
                    "~/Modules/{2}/Views/Shared/{0}.cshtml",
                    };

                    AreaMasterLocationFormats = new[]
                    {
                    "~/Modules/{2}/Views/{1}/{0}.cshtml", 
                    "~/Modules/{2}/Views/Shared/{0}.cshtml",
                    };

                    AreaPartialViewLocationFormats = new[]
                    {
                    "~/Modules/{2}/Views/{1}/{0}.cshtml", 
                    "~/Modules/{2}/Views/Shared/{0}.cshtml", 
                    };

                    ViewLocationFormats = new[]
                    {
                    "~/Views/{1}/{0}.cshtml", 
                    "~/Views/Shared/{0}.cshtml",
                    };

                    MasterLocationFormats = new[]
                    {
                    "~/Views/{1}/{0}.cshtml", 
                    "~/Views/Shared/{0}.cshtml", 
                    };
                    PartialViewLocationFormats = new[]
                    {
                    "~/Views/{1}/{0}.cshtml", 
                    "~/Views/Shared/{0}.cshtml", 
                    };

                    FileExtensions = new[] { "cshtml" };
                }

                protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath)
                {
                    string layoutPath = null;
                    var runViewStartPages = false;
                    IEnumerable<string> fileExtensions = base.FileExtensions;
                    return new RazorView(controllerContext, partialPath, layoutPath, runViewStartPages, fileExtensions);
                }

                protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath)
                {
                    string layoutPath = masterPath;
                    var runViewStartPages = true;
                    IEnumerable<string> fileExtensions = base.FileExtensions;
                    return new RazorView(controllerContext, viewPath, layoutPath, runViewStartPages, fileExtensions);
                }
            }
        }

2.Code:在Global.asax中添加注册区域-->AreaRegistration.RegisterAllAreas();

        public class ThemesAreaRegistration : AreaRegistration
            {
                public override string AreaName
                {
                    get
                    {
                        return "MvcProjectThemes";
                    }
                }

                public override void RegisterArea(AreaRegistrationContext context)
                {
                    context.MapRoute(
                        "MvcProjectThemes",
                        "MvcProjectThemes/{controller}/{action}/{id}",
                        new { controller = "Home", action = "Index", id = UrlParameter.Optional, },
                        namespaces: new string[] { "MvcProjectThemes.Controllers" }
                    );
                }
            }

3.Code:注册主项目MvcProjectMain的路由 RouteConfig.RegisterRoutes(RouteTable.Routes);

namespace MvcProjectMain
{
    public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
                namespaces: new string[] { "MvcProjectMain.Controllers" }
            );
        }
    }
}

最后

主要代码就是步骤1中的ThemableRazorViewEngine.cs类。自定义查找路径，其他的都是MVC的基础知识了,不懂自行查阅资料
