C#读取thumbs.db文件中的缩略图
问题：C#如何读取thumbs.db里的缩略图?
需要下载一个控件
ThumbDBLib，A C# library for reading thumbs.db file
引用dll，Thumbs.aspx,添加一个ID为plcThumbs 的PlaceHolder
<form id ="form1" runat ="server">
<div>
<asp:PlaceHolder id ="plcThumbs" runat ="server" EnableViewState ="False" ></asp:PlaceHolder>
</div>
</form>
C#主要代码：
string ThumbDb = Server.MapPath( " . " ) + " //thumbs.db " ;
if (System.IO.File.Exists(ThumbDb))
{
ThumbDBLib.ThumbDB ThumbLib = new ThumbDBLib.ThumbDB(ThumbDb);
if ((Request.QueryString[ " thumb " ] != null ))
{
string Thumb = Request.QueryString[ " thumb " ];
byte [] ThumbData = ThumbLib.GetThumbData(Thumb);
Response.Clear();
Response.ContentType = " image/ " + System.IO.Path.GetExtension(Thumb).ToLower().Replace( " . " , "" );
Response.BinaryWrite(ThumbData);
Response.Flush();
Response.End();
}
else
{
foreach ( string thumb in ThumbLib.GetThumbfiles())
{
if (System.IO.File.Exists(Server.MapPath( " . " ) + " // " + thumb))
{
// Could use a Literal control here if you want more
// control over the html.
System.Web.UI.WebControls.Image ThumbImage = new System.Web.UI.WebControls.Image();
ThumbImage.ImageUrl = " thumbs.aspx?thumb= " + Server.UrlEncode(thumb);
ThumbImage.ImageAlign = ImageAlign.Top;
ThumbImage.AlternateText = thumb;
ThumbImage.BorderStyle = BorderStyle.Outset;
ThumbImage.BorderWidth = new Unit( 1 );
ThumbImage.Attributes.Add( " hspace " , " 4 " );
ThumbImage.Attributes.Add( " vspace " , " 4 " );
ThumbImage.Attributes.Add( " onclick " , " window.location.href=' " + thumb + " '; " );
ThumbImage.Style.Add( " cursor " , " hand " );
plcThumbs.Controls.Add(ThumbImage);
}
}
}
ThumbLib = null ;
}
else
{
Response.Write( " Thumbs.db Not Found! " );
}// xt 和 image 数据类型。
