做个参考吧,跟之前的有个问题类似
- HTML code
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<body>
<form id="form1" runat="server">

alt="pic"/></div>
</form>
<asp:Image ID="Image1" runat="server"/>
</body>
</html>
handler2.ashx
<%@ WebHandler Language="C#" Class="Handler2"%>
using System;
using System.Web;
using System.IO;
using System.Drawing;
publicclass Handler2 : IHttpHandler {
publicvoid ProcessRequest(HttpContext context)
{
string path = context.Request.QueryString["path"];
if (!string.IsNullOrEmpty(path))
{
FileStream fs =new FileStream(@path, FileMode.Open, FileAccess.Read);
Bitmap myImage =new Bitmap(fs);
//输出到浏览器
MemoryStream ms =new MemoryStream();
myImage.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
context.Response.ClearContent();
context.Response.ContentType ="image/Jpeg";
context.Response.BinaryWrite(ms.ToArray());
}
}
publicbool IsReusable {
get {
returnfalse;
}
}
}
几个要注意的地方：
URL带有中文
页面后台代码:s
public string GoUen(object str)
{
string Result="";
if (str != null)
{
Result = Server.UrlEncode(str.ToString());
}
return Result;
}
前台调用:
<img runat="server" src= '<%#"Handler1.ashx?path="+GoUen(Eval("Address"))%>'
hasx接收时:
string path = HttpContext.Current.Server.UrlDecode(context.Request.QueryString["path"]);
