在文本区域中显示来自数据库的逗号分隔值？

Question

我真的找了找了也没有找到答案。鉴于一篇文章可以有多个标签，我想将标签显示为逗号分隔值，以便在编辑文章时它看起来像 Egypt, Sinai, Muslim Brotherhood 在文本区域中。如果对答案有帮助，我将 post 提供所需的任何代码。

我的模型是：

Partial Public Class be_Posts
        <Key>
        Public Property PostRowID As Integer
        Public Property BlogID As Guid
        Public Property PostID As Guid
        <StringLength(255)>
        Public Property Title As String
        Public Property Description As String
        <AllowHtml> Public Property PostContent As String
        Public Property DateCreated As Date?
        Public Property DateModified As Date?
        <StringLength(50)>
        Public Property Author As String
        Public Property IsPublished As Boolean?
        Public Property IsCommentEnabled As Boolean?
        Public Property Raters As Integer?
        Public Property Rating As Single?
        <StringLength(255)>
        Public Property Slug As String
        Public Property IsDeleted As Boolean
        Public Overridable Property be_PostTag As ICollection(Of be_PostTag)
        Public Overridable Property be_Categories As ICollection(Of be_Categories)

End Class

和 be_PostTag 模型

Partial Public Class be_PostTag
    <Key>
    Public Property PostTagID As Integer
    Public Property BlogID As Guid
    Public Property PostID As Guid
    <StringLength(50)>
    Public Property Tag As String
    Public Property be_Posts As ICollection(Of be_Posts)
End Class

我正在使用现有的数据库和数据，模型是从数据库中的代码优先生成的。

我意识到我需要一个 EditorTemplate 但除此之外我不知道该做什么。我如何将多个值绑定到单个文本区域？

一张图片来说明我在说什么：

已解决：

将其放入编辑器模板中：

    @modeltype IEnumerable(Of BetterBlog.Core.Entities.be_PostTag)

@code

    Dim sb As New StringBuilder

    For Each x In Model
        Dim tags = x.Tag & IIf(x.Equals(Model.Last), "", ", ")
        sb.Append(tags)

    Next

    @Html.TextArea("PostTags", sb.ToString, 10, 50, nothing)
End Code
