Question

如何将查询字符串值传递给ASP.net MVC app中具有默认值的视图模型参数？

我试过但没有成功;

public ActionResult Index(MyAnotherVM filter){
  // filter.p doesn't set passed value and it equals to 1
}

public class MyAnotherVM {
 public int p { get { return 1; } set { } }
 // or
 public int p=1;
}

Answer 1

您可以使用TempData

version: '3'
services:
  client:
    build: ./client
    volumes:
      - ./client:/usr/src/app
    ports:
      - "4200:4200"
      - "9876:9876"
    links:
      - api
    command: bash -c "yarn --pure-lockfile && yarn start"
  sidekiq:
    build: .
    command: bundle exec sidekiq
    volumes:
      - .:/api
    depends_on:
      - db
      - redis
      - api
  redis:
    image: redis
    ports:
      - "6379:6379"
  db:
    image: postgres
    ports:
      - "5433:5432"
  api:
    build: .
    command: bash -c "rm -f tmp/pids/server.pid && bundle exec rails s -p 3000 -b '0.0.0.0'"
    volumes:
      - .:/myapp
    ports:
      - "3000:3000"
    depends_on:
      - db

方法2：

使用传递的查询字符串数据

或者你可以借助查询字符串来构建它，比如

[HttpPost]
public ActionResult FillStudent(Student student1)
{
    TempData["student"]= new Student();
    return RedirectToAction("GetStudent","Student");
    }

[HttpGet]
public ActionResult GetStudent(Student passedStd)
{
    Student std=(Student)TempData["student"];
    return View();
}

这会生成GET请求，例如

return RedirectToAction("GetStudent","Student", new {Name="John",             Class="clsz"});

但请确保您有[HttpGet]，因为RedirectToAction将发出GET请求（302）
