我正在为网格生成以下 hml:
<form method="POST" action="home/Edit">
<table>
<thead>
<tr>
<th> Level </th>
<th> Cost </th>
<th> Test </th>
</tr>
</thead>
<tbody>
<tr>
<td> <input type='text' name="Prize[0].Level" value='1' /> </td>
<td> <input type='text' name="Prize[0].Cost" value='$1.00' /> </td>
<td> <input type='text' name="Prize[0].Properties['Test'].Name" value='Passed' /> </td>
</tr>
<tr>
<td> <input type='text' name="Prize[1].Level" value='2' /> </td>
<td> <input type='text' name="Prize[1].Cost" value='$2.00' /> </td>
<td> <input type='text' name="Prize[1].Properties['Test'].Name" value='Failed' /> </td>
</tr>
</tbody>
</table>
<input type="submit"/>
</form>
我的 Home 控制器有一个方法:
[HttpPost]
public ActionResult Edit(PrizelevelsModel model) { ... }
模型定义如下:
public class PrizelevelsModel
{
public PrizeLevel[] Prize { get; set; }
}
public class PrizeLevel
{
public readonly Dictionary<string, PrizeLevelProperty> Properties = new Dictionary<string, PrizeLevelProperty>();
public int Level { get; set; }
public decimal Cost { get; set; }
}
public class PrizeLevelProperty
{
public int Ordinal { get; set; }
public string Name { get; set; }
public object Value { get; set; }
}
当我点击提交时,MVC 用 Prize[2] 膨胀我的模型,数组中的每个 Prizelevel 都有正确的 Level 和 Cost,但是 Properties 字典有 0 个元素。如何让 MVC 将键为“Test”的元素添加到每个奖品的属性字典中,值是新的 PrizeLevelProperty,其名称与每个奖品的表单中设置的名称相同?
换句话说,当我调试我的控制器方法时,我想看到:
model.Prize[0].Level == 1 // this works ok
model.Prize[0].Cost == "$1.00" // and so does this
model.Prize[0].Properties["Test"].Name" == "Passed" // but not this, instead model.Prize[0].Properties.Count == 0
