问题,这是ASP.NET的代码,在WINFROM中运行的时候,由于没有 Response对象的,要怎么改一下呢?
//Response.ClearContent();
//Response.ContentType = "image/Gif";
//Response.BinaryWrite(ms.ToArray());

在下面代码里面,你不是有一个image对象吗?直接放在winform的pictutebox中就可以了
System.IO.MemoryStream ms = new System.IO.MemoryStream();
image.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);
picturebox1.image=image;
我明白了,简单问题,一会儿Winform,一会儿ASP.NET,头都晕了
