在另一个程序集中找到剃须刀页面 [英] Locate Razor Pages in another assembly

问题描述

我想在另一个程序集中找到我的Project Razor页面". 为此，我编写了以下代码:

I want to locate My Project Razor Pages in another assembly. for doing this I write following code:

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<RazorViewEngineOptions>(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:

在运行localhost:5000/SameTodo时出现以下错误:

when running localhost:5000/SameTodo Get Following Error:

缺少一个或多个编译参考.确保您的项目引用的是"Microsoft.NET.Sdk.Web"，并且"PreserveCompilationContext"属性未设置为false.

One or more compilation references are missing. Ensure that your project is referencing 'Microsoft.NET.Sdk.Web' and the 'PreserveCompilationContext' property is not set to false.

堆栈:

并将PreserveCompilationContext设置为false，但现在可以解决该问题了吗?

and set PreserveCompilationContext to false but now worked how can I solve this problem?

推荐答案

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<RazorViewEngineOptions>(options =>
    {
        options.FileProviders.Add(new EmbeddedFileProvider(Assembly.Load("App")));
        options.FileProviders.Add(new PhysicalFileProvider(@"C:\Users\soheil\Documents\Visual Studio 2017\Projects\WebApplication5\App"));
    });
}
