I have to post image src attribute to view.So i have tried in the following way
我必须将图像src属性发布到view.So我已经尝试过以下方式
Razor View:
剃刀视图：
@using (Html.BeginForm("MapIcon", "test", FormMethod.Get))
{
<div class="selected" id="selectable_images">
<table>
<tr>
<td>
<img src="../../Images/wi0096-48.gif" alt="Image1" class="conversation_img" />
</td>
<td>
<img src="../../Images/down.png" alt="image2" />
</td>
<td>
<img src="../../Images/wi0054-48.gif" alt="Image3" />
</td>
<td>
<img src="../../Images/Photo-icon.png" alt="image4" />
</td>
</tr>
<tr>
<td>
<img src="../../Images/wi0062-48.gif" alt="image5" />
</td>
<td>
<img src="../../Images/wi0064-48.gif" alt="image6" />
</td>
<td>
<img src="../../Images/wi0126-48.gif" alt="image7" />
</td>
<td>
<img src="../../Images/wi0126-48.gif" alt="image8" />
</td>
</tr>
<tr>
<td>
<img src="../../Images/wi0063-64.gif" alt="image9" />
</td>
<td>
<img src="../../Images/wi0064-48.gif" alt="image10" />
</td>
<td>
<img src="../../Images/wi0009-48.gif" alt="image11" />
</td>
<td>
</td>
</tr>
<tr>
<td>
<img src="../../Images/wi0126-48.gif" alt="iamg12" />
</td>
<td>
<img src="../../Images/wi0124-48.gif" alt="image13" />
</td>
<td>
<img src="../../Images/wi0062-48.gif" alt="image14" />
</td>
<td>
</td>
</tr>
</table>
</div>
}
@using (Html.BeginForm("MapIcon", "test", FormMethod.Post, new { id = "postform" }))
{
<input id="image2" type="hidden" name="image" value="../../Images/down.png">
<input id="Image3" type="hidden" name="image" value="../../Images/wi0054-48.gif">
<input id="image4" type="hidden" name="image" value="../../Images/Photo-icon.png">
<input type="submit" value="Match" />
foreach (var m in (List<string>) ViewData["list"]) //I am getting Null value here
{
<ul>
<li>
<img src="@m" alt=""/>
</li>
</ul>
}
}
Controller:
控制器：
[HttpPost]
public ActionResult MapIcon(IEnumerable<string> image)
{
List<string> urls = new List<string>();
string val = "";
foreach (var item in image)
{
val = item;
urls.Add(val);
//ViewBag.list = val;
ViewData["list"] = urls; ;
}
return View();
}
My main problem is that i have to show those images which are selected. I have tried but not succedded. The value of img tag are obtained in controller. But how to send these values again back to view?
我的主要问题是我必须显示那些被选中的图像。我试过但没有成功。 img标签的值在控制器中获得。但是如何将这些值再次发送回来查看？

Have you tried passing the data in your view with a model?
您是否尝试使用模型在视图中传递数据？
[HttpPost]
public ActionResult MapIcon(IEnumerable<string> image)
{
return View(image);
}
With in your view:
在您看来：
@model IEnumerable<string>
using (Html.BeginForm())
{
foreach (var m in Model)
{
<ul>
<li>
<img src="@m" alt=""/>
</li>
</ul>
}
}

[HttpPost]
public ActionResult MapIcon(IEnumerable<string> image)
{
List<string> urls = new List<string>();
string val = "";
foreach (var item in image)
{
val = item;
urls.Add(val);
//ViewBag.list = val;
//ViewData["list"] = urls; ;
}
return View(urls);
}
On View
在视图上
@foreach(var item in Model)
{
<p> @item.url</p>
}
