我有一个需要以下功能的场景：

In View I have call as:
$.ajax({
    type: "POST",
    async: false,
    dataType: 'json',
    url: "ControllerA/ActionA",
    data: { var1: some_value },
    success: function (data) {
        if (data == true) {
            form.submit();
        }
        else if (data == false) {
    }
});

// In ControllerA
public JsonResult ActionA(string var1)
{
    /*
 Some manipulation and calculations
 */
 _slist = RedirectToAction("ActionC", "ControllerB", new { var1 = some_value});
 string = _slist.First().ToString();

    return RedirectToAction("ActionB", "ControllerB", new { var1 = var2 });
}

// In ControllerB
public JsonResult ActionB(string var1)
{
    /*
 Some manipulation and calculations
 */

    return Json(false, JsonRequestBehavior.AllowGet);
}

public SelectList ActionC(string var1)
{    
 /*
 Some manipulation and calculations
 */

 Session["STRING"] = some_value;

 return new SelectList(_storeOrderTimeDictionaryList, "Value", "Key");
}

我需要查看页面中的 JsonResult，但问题如下：

  1. 由于 RedirectToAction 返回 redirecttorouteresult 我不能直接返回 JSonResut
  2. 由于我需要 ActionC 中的 Session，我无法实例化 Controller 并调用该操作。

这可能不是最好的方法......

这很难说，但是干掉控制器，移出业务逻辑可能会有所帮助。看起来您想要维护操作 B 和 C 的功能。

$.ajax({
    type: "POST",
    async: false,
    dataType: 'json',
    url: "ControllerA/ActionA",
    data: { var1: some_value },
    success: function (data) {
        if (data == true) {
            form.submit();
        }
        else if (data == false) {
    }
});


public Class CalculationsA
{
   public void DoCalculation() {}
}

public Class CalculationsB
{
   public void DoCalculation() {}
}

public Class CalculationsC
{
   public IQueryable<somethign> DoCalculation() {}
}


//_a is declared in Controller A as CalculationsA
//_b is declared in Controller B as CalculationsB 
//_c is declared in Controller C as CalculationsC

// In ControllerA
public JsonResult ActionA(string var1)
{
  _a.DoCalculation(); 
  _slist = _b.DoCalculation().First().ToString();

  Session["STRING"] = some_value;
  _c.DoCalculation();          

  /* your other logic... */

  return Json(retval, JsonRequestBehavior.AllowGet);
}

// In ControllerB
public JsonResult ActionB(string var1)
{
    _b.DoCalculation();

    return Json(false, JsonRequestBehavior.AllowGet);
}

public SelectList ActionC(string var1)
{    
 _c.DoCalculation();

 Session["STRING"] = some_value;

 return new SelectList(_storeOrderTimeDictionaryList, "Value", "Key");
}

顺便说一句，您应该查看Ninject、Castle Windsor、Structure Map 或任何其他 DI/IOC 容器，以帮助您测试此逻辑（并使其更干燥）。尝试搜索ninject asp.net mvc 2教程

您能否重构控制器操作以将其提取Some manipulation and calculations到另一个类或服务层函数调用中。

由于我需要 ActionC 中的 Session，我无法实例化 Controller 并调用该操作。

没有什么能阻止您在ControllerA.ActionA. 以下内容不准确，但可能对您有所帮助..

public class ControllerA{
    public JsonResult ActionA(string var1)
    {
     /*  Some manipulation and calculations    */
         SomeService service = new SomeService();
         _slist = service.ActionThatDoesStuffForActionC(var1);
         Session["STRING"] = var1;
         var firstItem = _slist.First().ToString();

         SomeOtherService service2 = new SomeOtherService();
         var service2Result = service2.ActionThatDoesStuffForActionB(firstItem);

         // convert service2Result  to a jsonresult here.

         return RedirectToAction("ActionB", "ControllerB", new { var1 = firstItem });
     }
}

public class ControllerB{
     public JsonResult ActionB(string var1)
     {
          /*    Some manipulation and calculations    */
          SomeOtherService service2 = new SomeOtherService();
          var service2Result = service2.ActionThatDoesStuffForActionB(var1);

          return Json(false, JsonRequestBehavior.AllowGet);
     }

    public SelectList ActionC(string var1)
     {    
     /*     Some manipulation and calculations     */
     SomeService service = new SomeService();
     _slist = service.ActionThatDoesStuffInActionC(var1);
     Session["STRING"] = var1;
     return new SelectList(_slist, "Value", "Key");
    }   
}

编辑：从这里查看源代码http://www.lostechies.com/blogs/jimmy_bogard/archive/2010/07/23/mvcconf-slides-and-code-posted.aspx。我认为 Jimmy Boggard 的方法可能很有用，并为您提供了一种调用“其他控制器”操作的方法。你评论'我不能改变动作的行为。并且重构它需要我没有的时间。对我来说，这表明了通往无法维护的代码的旅程。重构、重构、重构——现在做的好处将在以后的阶段为您节省数小时的心痛。基于这个问题，我认为它已经开始了。
