动态生成LinkButton控件,动态添加事件调用一个方法Public Sub Download(ByVal oResponse As System.Web.HttpResponse, ByVal FileName As String, ByVal strFileNamePrompt As String) Dim oFile As System.IO.FileInfo = New System.IO.FileInfo(FileName) oResponse.AddHeader("Content-Disposition", "attachment;filename=" & HttpUtility.UrlEncode(strFileNamePrompt)) oResponse.AddHeader("Content-Length", oFile.Length.ToString()) oResponse.ContentType = "APPLICATION/OCTET-STREAM" oResponse.WriteFile(oFile.FullName) oResponse.End() End Sub

String[] files = Directory.GetFiles(directoryPath);
遍历数组，得到文件的名字，生成这样的格式
down.aspx?name=filename关于下载，网上有很多代码，在此不重复。搜索asp.net 下载文件
Dim oFile As System.IO.FileInfo = New System.IO.FileInfo(FileName)
oResponse.AddHeader("Content-Disposition", "attachment;filename=" & HttpUtility.UrlEncode(strFileNamePrompt))
oResponse.AddHeader("Content-Length", oFile.Length.ToString())
oResponse.ContentType = "APPLICATION/OCTET-STREAM"
oResponse.WriteFile(oFile.FullName)
oResponse.End()
End Sub
