Hi
Below is example code for file uploading in ASP.Net 2.0
Code:
<%@ Page Language="VB" %>
<%@ Import Namespace="System.IO" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
Sub btnAdd_Click(ByVal sender As Object, ByVal e As EventArgs)
If (upImage.HasFile) Then
If (CheckFileType(upImage.FileName)) Then
Dim filePath As String = "~/UploadImages/" & upImage.FileName
upImage.SaveAs(MapPath(filePath))
End If
End If
End Sub
Function CheckFileType(ByVal fileName As String) As Boolean
Dim ext As String = Path.GetExtension(fileName)
Select Case ext.ToLower()
Case ".gif"
Return True
Case ".png"
Return True
Case ".jpg"
Return True
Case ".jpeg"
Return True
Case Else
Return False
End Select
End Function
Sub Page_PreRender()
Dim upFolder As String = MapPath("~/UploadImages/")
Dim dir As New DirectoryInfo(upFolder)
dlstImages.DataSource = dir.GetFiles()
dlstImages.DataBind()
End Sub
</script>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
<title>FileUpload File</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Label
id="lblImageFile"
Text="Image File:"
AssociatedControlID="upImage"
Runat="server" />
<asp:FileUpload
id="upImage"
Runat="server" />
<br /><br />
<asp:Button
id="btnAdd"
Text="Add Image"
OnClick="btnAdd_Click"
Runat="server" />
<hr />
<asp:DataList
id="dlstImages"
RepeatColumns="3"
runat="server">
<ItemTemplate>
<asp:Image ID="Image1"
ImageUrl='<%# Eval("Name", "~/UploadImages/{0}") %>'
style="width:200px"
Runat="server" />
<br />
<%# Eval("Name") %>
</ItemTemplate>
</asp:DataList>
</div>
</form>
</body>
</html>
Hope this helps a bit? Its a very simple example, but should hopefully set you on the right track.
