问题描述
当将Razor类库与ASP.net core 2.1一起使用时,如果我添加对类库的引用,它将按预期加载控制器和视图. 但是问题是,如何在运行时动态加载此模块? 我想将模块放在设计时未引用的目录中,并在应用程序启动时加载它们. 我尝试使用应用程序部件.但是那样的话,控制器就被加载了,但是却没有发现视图.
When using Razor Class Libraries with ASP.net core 2.1, if I add reference to the class library, it loads controllers, and views as expected. But the question is, how can I load this modules dynamically at runtime? I want to put modules at directory, which are not referenced at design time, and load them at the start up of the app. I tried to use Application Parts. But that way, controllers are loaded, but views are not discovered.
推荐答案
我完全忘记了CompiledRazorAssemblyPart.
I had completely forgot about CompiledRazorAssemblyPart.
我们需要做的是:
services.AddMvc()
.SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
.ConfigureApplicationPartManager(ConfigureApplicationParts);
并配置类似的部分
private void ConfigureApplicationParts(ApplicationPartManager apm)
{
var rootPath = HostingEnvironment.ContentRootPath;
var pluginsPath = Path.Combine(rootPath, "Plugins");
var assemblyFiles = Directory.GetFiles(pluginsPath, "*.dll", SearchOption.AllDirectories);
foreach (var assemblyFile in assemblyFiles)
{
try
{
var assembly = Assembly.LoadFile(assemblyFile);
if (assemblyFile.EndsWith(".Views.dll"))
apm.ApplicationParts.Add(new CompiledRazorAssemblyPart(assembly));
else
apm.ApplicationParts.Add(new AssemblyPart(assembly));
}
catch (Exception e) { }
}
}
