blocks|key|2292347|text|这就是我认为你能做的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2292348|首先声明一个任意名称的class，我将使用SampleClass|offset|length|style|CODE|2292349|public+class+SampleClass
{
++++public+int+Id+{+get;+set;+}
++++public+string+Category+{+get;+set;+}
++++public+string+DisplayName+{+get;+set;+}

++++public+string+FieldLength+{+get;+set;+}
++++public+int+IsRequired+{+get;+set;+}//you+can+convert+this+to+boolean+to+make+it+easier
}|code-block|syntax|javascript|2292350|其次，从控制器中的db填充这个类|2292351|//assuming+you+are+using+linq+query
var+allEntry+=+context.Table.Where(m+=>+m.Category+==+SelectedCategory);
var+allViews+=+new+List<SampleClass>();

{
++++allViews.Add(new+SampleClass
++++{

++++++++//and+so+on...

++++});
}|2292352|第三，在视图中，按照我在评论中所说的那样做|2292353|@using+(Html.BeginForm("ActionName",+"ControllerName",+FormMethod.Post,+new+{+@class+=+"forms-horizontal",+role+=+"form"+}))
{
++++<div+class="form-horizontal">

++++++++@foreach+(var+a+in+List<SampleClass>)//note+this(List<SampleClass>)+will+be+passed+from+the+controller+to+the+view.
++++++++{
++++++++++++switch+(a.FieldType)
+++++++++++++{
++++++++++++++++case+"Test":
++++++++++++++++++++<div+class="form-group">
++++++++++++++++++++++++<label+for="@a.FieldName"></label>
++++++++++++++++++++++++<input+id="@a.FieldName"+type="text"+name="@a.FieldName"+required="@(a.IsRequired+==+1+?+"required"+:+"")"+/>
++++++++++++++++++++</div>
++++++++++++++++++++break;
++++++++++++++++case+"Number":
++++++++++++++++++++<div+class="form-group">
++++++++++++++++++++++++<label+for="@a.FieldName"></label>
++++++++++++++++++++++++<input+id="@a.FieldName"+type="number"+name="@a.FieldName"+required="@(a.IsRequired+==+1+?+"required"+:+"")"+/>
++++++++++++++++++++</div>
++++++++++++++++++++break;
++++++++++++++++case+"Select":
++++++++++++++++++++<div+class="form-group">
++++++++++++++++++++++++<label+for="@a.FieldName"></label>
++++++++++++++++++++++++@Html.DropDownList(a.FieldName,+new+SelectList(DbUtils.GetEvaluations(),+"Value",+"Text",+null),+"Select..",+new+{+@required+=+@a.IsRequired+==+1+?+"required"+:+""+})
++++++++++++++++++++</div>
++++++++++++++++++++break;
++++++++++++}
++++++++}
++++++++<div+class="form-group">
++++++++++++<div+class="col-md-offset-3+col-md-9">
++++++++++++++++<input+type="submit"+value="Submit"+class="btn+btn-primary"+/>
++++++++++++</div>
++++++++</div>
++++</div>
}|2292354|根据需要，您可以在select子句中使用更多的cases。|2292355|希望这能帮上忙..|2292356|entityMap^0|0|B|5|L|B|0|0|0|0|0|0|N|5|0|0^^$0|@$1|2|3|4|5|6|7|10|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|11|8|@$D|12|E|13|F|G]|$D|14|E|15|F|G]]|9|@]|A|$]]|$1|H|3|I|5|J|7|16|8|@]|9|@]|A|$K|L]]|$1|M|3|N|5|6|7|17|8|@]|9|@]|A|$]]|$1|O|3|P|5|J|7|18|8|@]|9|@]|A|$K|L]]|$1|Q|3|R|5|6|7|19|8|@]|9|@]|A|$]]|$1|S|3|T|5|J|7|1A|8|@]|9|@]|A|$K|L]]|$1|U|3|V|5|6|7|1B|8|@$D|1C|E|1D|F|G]]|9|@]|A|$]]|$1|W|3|X|5|6|7|1E|8|@]|9|@]|A|$]]|$1|Y|3|-4|5|6|7|1F|8|@]|9|@]|A|$]]]|Z|$]]

<p>This is what I think you can do.</p>

<p>First declare a <code>class</code> call it any name, I will use <code>SampleClass</code></p>

<pre><code>public class SampleClass
{
    public int Id { get; set; }
    public string Category { get; set; }
    public string DisplayName { get; set; }
    public string FieldName { get; set; }
    public string FieldType { get; set; }
    public string FieldLength { get; set; }
    public int IsRequired { get; set; }//you can convert this to boolean to make it easier
}
</code></pre>

<p>Secondly, populate this class from the db in the Controller</p>

<pre><code>//assuming you are using linq query
var allEntry = context.Table.Where(m =&gt; m.Category == SelectedCategory);
var allViews = new List&lt;SampleClass&gt;();
foreach (var entry in allEntry)
{
    allViews.Add(new SampleClass
    {
        FieldName = entry.FieldName,
        //and so on...

    });
}
</code></pre>

<p>Third and in the view do this as I said in the comment</p>

<pre><code>@using (Html.BeginForm("ActionName", "ControllerName", FormMethod.Post, new { @class = "forms-horizontal", role = "form" }))
{
    &lt;div class="form-horizontal"&gt;
        &lt;h4&gt;Title of the form&lt;/h4&gt;
        &lt;hr /&gt;&lt;br /&gt;
        @foreach (var a in List&lt;SampleClass&gt;)//note this(List&lt;SampleClass&gt;) will be passed from the controller to the view.
        {
            switch (a.FieldType)
             {
                case "Test":
                    &lt;div class="form-group"&gt;
                        &lt;label for="@a.FieldName"&gt;&lt;/label&gt;
                        &lt;input id="@a.FieldName" type="text" name="@a.FieldName" required="@(a.IsRequired == 1 ? "required" : "")" /&gt;
                    &lt;/div&gt;
                    break;
                case "Number":
                    &lt;div class="form-group"&gt;
                        &lt;label for="@a.FieldName"&gt;&lt;/label&gt;
                        &lt;input id="@a.FieldName" type="number" name="@a.FieldName" required="@(a.IsRequired == 1 ? "required" : "")" /&gt;
                    &lt;/div&gt;
                    break;
                case "Select":
                    &lt;div class="form-group"&gt;
                        &lt;label for="@a.FieldName"&gt;&lt;/label&gt;
                        @Html.DropDownList(a.FieldName, new SelectList(DbUtils.GetEvaluations(), "Value", "Text", null), "Select..", new { @required = @a.IsRequired == 1 ? "required" : "" })
                    &lt;/div&gt;
                    break;
            }
        }
        &lt;div class="form-group"&gt;
            &lt;div class="col-md-offset-3 col-md-9"&gt;
                &lt;input type="submit" value="Submit" class="btn btn-primary" /&gt;
            &lt;/div&gt;
        &lt;/div&gt;
    &lt;/div&gt;
}
</code></pre>

<p>You can have more <code>cases</code> in your select clause depending on what you need.</p>

<p>Hope this helps..</p>


<p><strong>Screenshot of table structure with data</strong>
<img src="https://i.stack.imgur.com/4OAHz.jpg" alt="">
Table structure is as below:</p>

<pre><code>Id | Category | DisplayName | FieldName | FieldType | FieldLength | IsRequired
</code></pre>

<p>Please see screenshot for details.</p>

<p>On selection of a category all HTML fields defined in table against that category should populate in view.</p>

<p>And how to validate on form submit.</p>

<p>I have more than 400 categories.</p>
