public static List<Flow_HelpModel> ForeachClassProperties<T>(T model)
{
int i = 0;
Type t = model.GetType();
List<Flow_HelpModel> list = new List<Flow_HelpModel>();
Flow_HelpModel helpmodel = new Flow_HelpModel();
PropertyInfo[] propertyList = t.GetProperties();
foreach(PropertyInfo item in propertyList)
{
i++;
if (i > 8)
{
if (item.Name != null)
{
object value = item.GetValue(model, null);
Flow_FormAttrModel entity = A_BLL.GetById(value.ToString());
helpmodel.currentChar = "tr" + item.Name;
helpmodel.currentTitle = entity.Name;
helpmodel.currentValue = value.ToString();
helpmodel.Example = getExample(entity.AttrType);
list.Add(helpmodel);
}
}
}
return list;
}

这是后端调用

<table id="AttrList" class="fromEditTable setTextWidth3">
@foreach(var obj in ForeachClass.ForeachClassProperties(Model))
{

<tr id="@obj.currentChar">
<td style="text-align:right">
@obj.currentTitle
</td>
<td>
@obj.Example<input id="@obj.currentChar.Substring(2,obj.currentChar.Length)" name="@obj.currentChar.Substring(2,obj.currentChar.Length)" type="hidden" value="@obj.currentValue"/>
</td>
<td><a href="javascript:deleteCurrentTR('@obj.currentChar')">[删除]</a></td>
</tr>
}
</table>

前台我是用了一个foreach循环

但是一到调用A_BLL.GetById（）方法时就会出现错误未将对象引用到实例
