asp.net core, asp.net mvc6 项目中默认使用Razor ViewEngine,按"约定胜于配置"的原则,默认的项目结构是按Controller, Views, Model这样的文件结构来组织的,其中。
其中主所有的View放在了Views目录中。
如果需要改变View的位置,可以通过IViewLocationExpander接口来实现自定义,主要的是就是View的查找路径。
默认的项目文件结构是
/
/controllers/
/controllers/HomeController.cs
/Models/
/Models/SomeModel.cs
/Views/
/Views/shared/_layout.cshtml
/Views/Home/Index.cshtml
按模块重新组织后的项目,
/UI/
/UI/HOME/
/UI/HOME/controllers/
/UI/HOME/controllers/HomeController.cs
/UI/HOME/Models/SomeModel.cs
/UI/HOME/Views/Index.cshtml
/UI/SharedViews/_layout.cshtml
解决办法 就是 通过继承 IViewLocationExpander 接口,自定义一个View的发现路径(假设名为 MyViewLocationExpander.cs),如下。
public class MyViewLocationExpander : IViewLocationExpander
{
public IEnumerable<string> ExpandViewLocations(
ViewLocationExpanderContext context,
IEnumerable<string> viewLocations)
{
yield return "~/UI/{1}/Views/{0}.cshtml";
yield return "~/UI/{1}/{0}.cshtml";
yield return "~/UI/SharedViews/{0}.cshtml";
}
public void PopulateValues(ViewLocationExpanderContext context)
{
}
然后在 startup.cs 中注册下
public void ConfigureServices(IServiceCollection services)
{
// ...
services.AddMvc()
.AddRazorOptions(razor =>
{
razor.ViewLocationExpanders.Add(new IdSvrHost.UI.MyViewLocationExpander());
});
// ...
}
效果如下
