ThumbDBLib
A C# library for reading thumbs.db file
http://www.petedavis.net/MySite/DynPageView.aspx?pageid=31
引用dll,这里提供了 VB和C#代码,一个Thumbs.aspx,添加一个ID为plcThumbs 的@H_502_15@PlaceHolder
@H_301_19@
VB主要代码:

Dim Thumb As String = Request.QueryString( @H_502_15@" @H_502_15@thumb @H_502_15@" )
Dim ThumbData As Byte () = ThumbLib.GetThumbData(Thumb)
Response.Clear()
Response.ContentType = @H_502_15@" @H_502_15@image/ @H_502_15@" & System.IO.Path.GetExtension(Thumb).ToLower.Replace( @H_502_15@" @H_502_15@. @H_502_15@" , @H_502_15@"" )
