如何从 Mvc 中的控制器调用另一个控制器操作 [英] How to call another controller Action From a controller in Mvc

问题描述

我需要从控制器 A 调用控制器 B 的操作 FileUploadMsgView 并需要为其传递参数.

I need to call a controller B action FileUploadMsgView from Controller A and need to pass a parameter for it.

 Code---its not going to the controller B's FileUploadMsgView().
    In ControllerA
  private void Test()
    {

        try
        {//some codes here
            ViewBag.FileUploadMsg = "File uploaded successfully.";
            ViewBag.FileUploadFlag = "2";

            RedirectToAction("B", "FileUploadMsgView", new { FileUploadMsg = "File   uploaded successfully" });
        }

     In ControllerB receiving part
  public ActionResult FileUploadMsgView(string FileUploadMsg)
    {
         return View();
    }

推荐答案

控制器只是类 - 一个新的类，并像调用任何其他类成员一样调用 action 方法:

Controllers are just classes - new one up and call the action method just like you would any other class member:

var result = new ControllerB().FileUploadMsgView("some string");
