Having Issue On Passing Array to View From Controller in Asp.Net MVC

Question

I have a Controller action ActionResult which is listing all files in directory as:

public ActionResult Index()
{
    string[] txtFiles = Directory.GetFiles(Server.MapPath("~/TextFiles/"));
    return View(txtFiles);
}

and in index.cshtml I have

@model List<txtFiles>   
@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

<ul>
@foreach (var i in Model)
    {
        <li>@Html.ActionLink(System.IO.Path.GetFileName(i), "FileContent")</li>
    }
</ul>

but I am not sure what should I pass in model? I already tried @model List<txtFiles> but it didn't work and I am getting this error

thanks haim770, and can you please let me know what is the role of the @model IEnumerable<string> is doing here? — Suffii

Use @model string[] or @model IEnumerable instead of @model List.

Because txtFiles is not type. Hope this will help you.

You model is not a List<txtFiles> but a string[]

Change the model in your view.

@model List<txtFiles> should become @model string[] or @model IEnumerable<string>

Thanks Raphaël but can you please let me know what exactly the @model IEnumerable<string> is doing here?

In @model, you should have the TYPE of your model. txtFiles, which is what you send to view as model, is a string[] (this is what Directory.GetFiles returns) . And arrays implement IEnumerable, so you can use IEnumerable<string> also.

Instead of using List<txtFiles> please use string[] or IEnumerable<string> in Razor code. You tried to use txtFiles as a type, which is wrong becasuse it's name of variable.
