在另一个程序集中找到Razor Pages

我想在另一个程序集中找到My Project Razor Pages。 为此，我写下面的代码：

public void ConfigureServices(IServiceCollection services) { var adminAssembly = Assembly.Load(new AssemblyName("App")); services.AddMvc().AddApplicationPart(adminAssembly).AddRazorOptions(options => { var previous = options.CompilationCallback; options.CompilationCallback = context => { previous?.Invoke(context); context.Compilation = context.Compilation.AddReferences( MetadataReference.CreateFromFile(typeof(dodo).Assembly.Location)); }; }); services.Configure(options => { options.FileProviders.Add(new EmbeddedFileProvider(Assembly.Load("App"))); options.FileProviders.Add(new PhysicalFileProvider(@"C:\Users\soheil\Documents\Visual Studio 2017\Projects\WebApplication5\App")); }); } 

我的解决方案

运行localhost:5000/SameTodo获取以下错误：

缺少一个或多个编译引用。 确保您的项目引用了“Microsoft.NET.Sdk.Web”，并且“PreserveCompilationContext”属性未设置为false。

堆：

找不到类型或命名空间名称’SameTodoModel’（您是否缺少using指令或程序集引用？）+ public global :: Microsoft.AspNetCore.Mvc.Rendering.IHtmlHelper Html {get; 私人集; 无法找到类型或命名空间名称’SameTodoModel’（您是否缺少using指令或程序集引用？）+ public global :: Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary ViewData =>（global :: Microsoft.AspNetCore .Mvc.ViewFeatures.ViewDataDictionary）的PageContext .ViewData？; 找不到类型或命名空间名称’SameTodoModel’（您是否缺少using指令或程序集引用？）+ public SameTodoModel Model => ViewData.Model; 找不到类型或命名空间名称’SameTodoModel’（您是否缺少using指令或程序集引用？）+ public global :: Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary ViewData =>（global :: Microsoft.AspNetCore。 Mvc.ViewFeatures.ViewDataDictionary）的PageContext .ViewData？;

并将PreserveCompilationContext设置为false但现在工作如何解决此问题？

Answer 1

 public void ConfigureServices(IServiceCollection services) { var adminAssembly = Assembly.Load(new AssemblyName("App")); services.AddMvc().AddApplicationPart(adminAssembly).AddRazorOptions(options => { var previous = options.CompilationCallback; options.CompilationCallback = context => { previous?.Invoke(context); var referenceAssemblies = AppDomain.CurrentDomain.GetAssemblies() .Where(x => !x.IsDynamic&& !string.IsNullOrEmpty(x.Location)) .Select(x => MetadataReference.CreateFromFile(x.Location)) .ToList(); //add dynamic var dynamicAssembly = typeof(DynamicAttribute).Assembly; referenceAssemblies.Add(MetadataReference.CreateFromFile(dynamicAssembly.Location)); context.Compilation = context.Compilation.AddReferences(referenceAssemblies); }; }); services.Configure(options => { options.FileProviders.Add(new EmbeddedFileProvider(Assembly.Load("App"))); options.FileProviders.Add(new PhysicalFileProvider(@"C:\Users\soheil\Documents\Visual Studio 2017\Projects\WebApplication5\App")); }); } 

Answer 2

而不是新建AssemblyName，使用该程序集中的类型的引用：

var adminAssembly = typeof(SameTodoModel).Assembly;

此外，错误消息显示：’PreserveCompilationContext’属性未设置为false。

意思是它应该设置为true。

Answer 3

您是否需要在WebApplication5的_ViewImports.cshtml中使用@using语句？ 喜欢@using App.SameTodoModel
