asp.netcore 获取中间件列表

var applicationBuilderInfo = app.GetType().GetProperty("ApplicationBuilder", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.IgnoreCase);
var _componentsInfo = typeof(ApplicationBuilder).GetField("_components", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.IgnoreCase);
var applicationBuilder = applicationBuilderInfo.GetValue(app);
var midds= _componentsInfo.GetValue(applicationBuilder) as List<Func<RequestDelegate, RequestDelegate>>;
foreach (var x in midds)
{

}

这是基于dotnet7

var app = builder.Build();

builder.use 的时候，会给app.ApplicationBuilder._components  这个属性add 一个 Func<RequestDelegate, RequestDelegate>

ApplicationBuilder   和 _components 都是pravite, so 需要用反射得到

只是能看到有几个而已。具体源码怎么写的已经看不到了
