追加合并两个项目的IEnumerable [英] append two IEnumerable items
问题描述
的IEnumerable<地址> AddressSet1 = myServices.GetAddresses(LocationId1);
IEnumerable的<地址> AddressSet2 = myServices.GetAddresses(LocationId2);
我想上面的两个AddressSets结合
我试过的IEnumerable<地址> AllAddresses = AddressSet1.Concat(AddressSet2)
但毕竟这当我尝试自IEnumerable AllAddresses访问项目通过我的Razor视图
@if(!myHelper.IsNullorEmpty(model.AllAddresses)
{
@ Html.EditorFor(型号=> model.AllAddresses)
}
和我收到错误 - 路径中。任何建议,非法字符来确定该错误的原因
如果我试图用出的毗连我能看到AddressSet1 / AddressSet2记录显示在页面上运行我的网页。但是当我尝试将二者结合起来,形成我可枚举AllAddresses,它是引发错误,请帮助
下面粘贴是我的编辑模板
@model MyServiceRole.Models.Addresses
@ {
ViewBag.Title =所有地址的项目; }
<表>
&所述; TR>
&所述; TD>
<跨度>指数< / SPAN> < / TD>
&所述; TD>< / TR>
&所述; TR>

@ Html.EditorFor(型号=> model.AddressID)

我测试您的问题和遇到同样的问题。
列表<串GT;一个=新名单<串GT; {一};
清单<串GT; B =新的List<串GT; {B};IEnumerable的<串GT; CONCAT = a.Concat<串GT;(二);
的foreach(字符串s的Concat){} //这个作品返回查看(CONCAT);
在视图:
@model IEnumerable的<串GT;@foreach(字符串s的模型)//这炸毁
{
}
@ Html.EditorFor(M = GT;产品型号)//还鼓起
它看起来像你真的不能使用模板或枚举的
System.Linq.Enumerable.ConcatIterator< T>
类的毗连
视图中创建。这似乎是一个错误。
反正加入 .ToList()
解决您的问题。
返回查看(concat.ToList());
IEnumerable<Addresses> AddressSet1=myServices.GetAddresses(LocationId1);
IEnumerable<Addresses> AddressSet2=myServices.GetAddresses(LocationId2);
I want to combine the above two AddressSets
I tried IEnumerable<Addresses> AllAddresses=AddressSet1.Concat(AddressSet2)
But after this when I try to access items from IEnumerable AllAddresses by on my razor view
@if(!myHelper.IsNullorEmpty(model.AllAddresses )
{
@Html.EditorFor(model => model.AllAddresses )
}
and I am getting errors -- Illegal characters in path .Any suggestions to identify cause of this error ?
If I am trying to run my page with out the Concat I am able see the records in AddressSet1 /AddressSet2 displayed on the page .But when I try to combine the two to form I Enumerable AllAddresses ,it is throwing errors please help
pasted below is my Editor Template
@model MyServiceRole.Models.Addresses
@{
ViewBag.Title = "All addresses Items";
}
<table>
<tr>
<td>
<span>Index</span>
</td>
<td>
</tr>
<tr>
<td>Address XID</td>
<td>
@Html.EditorFor(model => model.AddressID)
</td>
</tr>
<tr>
<td>Title</td>
<td>
@Html.EditorFor(model => model.Title)
</td>
</tr>
<tr>
<td>Description</td>
<td>
@Html.EditorFor(model => model.Description)
</td>
</tr>
<tr>
<td>Image URL</td>
<td>
@Html.EditorFor(model => model.Photo.URL)
</td>
</tr>
</table>
I tested your issue and ran into the same problem.
List<string> a = new List<string>{ "a" };
List<string> b = new List<string>{ "b" };
IEnumerable<string> concat = a.Concat<string>(b);
foreach(string s in concat) { } // this works
return View(concat);
In view:
@model IEnumerable<string>
@foreach(string s in Model) //This blows up
{
}
@Html.EditorFor(m => Model) //Also blows up
It looks like you honestly can't use templates with or enumerate over the
System.Linq.Enumerable.ConcatIterator<T>
class that Concat
creates within a View. This seems like a bug.
Anyway adding .ToList()
fixes your issue.
return View(concat.ToList());
