MVC4-如何从剃刀视图调用控制器方法 [英] MVC4 - How to call controller method from razor view

问题描述

我是MVC的新手，有人可以帮助我，并从视图中解释如何调用控制器方法.

i am new with MVC, can someone please help me and explain how to call controller method from a view.

我有HomeController，里面有ShowFileContent()方法.

I have HomeController and inside it I have method ShowFileContent().

[HttpPost]
public ActionResult ShowFileContent()
{
    string filepath = Server.MapPath("\\Files\\Columns.txt");    
    try
    {
        var lines = System.IO.File.ReadAllLines(filepath);

        foreach (var line in lines)
        {
            ViewBag.FileContent += line + "\n";

        }
    }
    catch (Exception exc)
    {
        ViewBag.FileContent = "File not found";
    }

    return View();
} 

在内部视图中，我尝试使用下面的代码调用此方法，但是它不起作用.

Inside view I've tried to call this method with code bellow but it does not work.

@using (Html.BeginForm("ShowFileContent", "Home"))
{
    <input type="submit" value="Show File" style='width:300px'/>        
}
<h2>@Html.Raw(ViewBag.FileContent.Replace("\n", "</br>"))</h2>

我得到错误:找不到"ShowFileContent"视图或其主视图，或者没有视图引擎支持搜索到的位置.

I get error: The view 'ShowFileContent' or its master was not found or no view engine supports the searched locations.

我做错了什么?从剃刀视图调用方法的最佳方法是什么?

What i am doing wrong and whats the best way to call methods from razor view ?

推荐答案

在我看来，它像是在破坏您的

It sounds to me like its breaking on your

 return View();

如果您不告诉它去哪里，它会认为该视图与您的操作相同.

If you dont tell it where to go it thinks the view is called the same as your action.

所以尝试

return View("Name of your view");
