从目录中列出视图中的数据 [英] binding data in a list view from a directory

问题描述

我有一个列表视图：

i have a list view :

<asp:ListView ID="ListView1" runat="server">
          <ItemTemplate>
                <asp:ImageButton ID="ImageButton1" runat="server" />
          </ItemTemplate>
</asp:ListView>

我在vb中有图像的链接：

and i have the link of the images in vb:

Dim dirInfo As string="D:\rbi\images\emoticons\"
 Dim filenames As List(Of String) = dirInfo.GetFiles().[Select](Function(j) j.Name).ToList()

我从目录中获取的链接和文件名不是来自数据库...所以如何在列表视图中绑定这些链接以显示所有图像？

i'm getting the link and the filenames from the directory not from a database...so how can i bind these links in the list view to show all the images?

推荐答案

看一看，看看它是否更清楚你需要做什么。

Give this a look and see if it becomes a little clearer what you need to do.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    Dim dirInfo As String = "c:\path\to\files\"

    Dim di As New IO.DirectoryInfo(dirInfo)
    Dim diar1 As IO.FileInfo() = di.GetFiles()
    Dim dra As IO.FileInfo

    Dim lvData As New List(Of FileObject)
    Dim ctr As Int32 = 0 ' used for FileID (optional)

    'loop all the files in the specified directory
    For Each dra In diar1
        lvData.Add(New FileObject With {.FileID = ctr + 1, .FileName = dra.Name})
    Next

    ListView1.DataSource = lvData
    ListView1.DataBind()

End Sub

Public Class FileObject
    Private _fileName As String
    Public Property FileName() As String
        Get
            Return _fileName
        End Get
        Set(ByVal value As String)
            _fileName = value
        End Set
    End Property
    Private _fileID As Int32
    Public Property FileID() As Int32
        Get
            Return _fileID
        End Get
        Set(ByVal value As Int32)
            _fileID = value
        End Set
    End Property
    ' additional properties as needed, file size, etc...
End Class
