谁能看到为什么这个简单的测试网站会打印出一个空表(在html中，创建的表有2行(tr)，但没有生成任何单元格(td)).
Can anyone see why this simple test website is printing out an empty table (in teh html, a table is getting created with 2 rows (tr) but there are no cells (td) getting produced).
或者是进行调试的最佳方法是什么
Or how is the best way to go about debugging it
DebugController.cs ...
DebugController.cs...
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.Mvc;
namespace myproject.Controllers
{
public class type1
{
public String ipAddress;
public String connectionId;
}
public ActionResult Debug2(string arg1)
{
List<dynamic> obj1 = new List<dynamic>();
obj1.Add(new type1 {ipAddress="192.168.1.1", connectionId="123"});
obj1.Add(new type1 {ipAddress="192.168.1.2", connectionId="345"});
ViewBag.obj1 = obj1;
return View();
}
}
}
还有Debug2.cshtml ....
And Debug2.cshtml....
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="~/Scripts/jquery-1.8.2.js"></script>
<script type="text/javascript" src="~/Scripts/jquery.signalR-1.1.3.js"></script>
<script type="text/javascript" src="~/signalr/hubs"></script>
@{
var grid = new WebGrid(ViewBag.obj1);
}
</head>
<body>
<div>
@grid.GetHtml()
</div>
</body>
</html>
推荐答案
我可能会尝试更强类型的输入.
I'd probably try something a bit more strongly typed.
此外，IIRC您还必须在模型上使用属性，而不是在字段上使用属性，以便WebGrid帮助器可以选择它们:
Also IIRC you must use properties on your model instead of fields so that the WebGrid helper could pick them up:
public class Type1
{
public string IPAddress { get; set; }
public string ConnectionId { get; set; }
}
以及您的操作:
public ActionResult Debug2(string arg1)
{
var model = new List<Type1>();
model.Add(new Type1 { IPAddress = "192.168.1.1", ConnectionId = "123" });
model.Add(new Type1 { IPAddress = "192.168.1.2", ConnectionId = "345" });
return View(model);
}
最后进入您的强类型视图:
and finally in your strongly typed view:
@model IList<Type1>
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="~/Scripts/jquery-1.8.2.js"></script>
<script type="text/javascript" src="~/Scripts/jquery.signalR-1.1.3.js"></script>
<script type="text/javascript" src="~/signalr/hubs"></script>
@{
var grid = new WebGrid(Model);
}
</head>
<body>
<div>
@grid.GetHtml()
</div>
</body>
</html>
