System.IO.MemoryStream ms = new System.IO.MemoryStream();

//输出图片
Response.ClearContent();
Response.ContentType = "image/Jpeg";
Response.BinaryWrite(ms.ToArray());
}
finally
{
g.Dispose();
image.Dispose();
}
以上代码是在asp.net下运行的，可以用Response输出图片，但是在winform程序下如何输出生成的曲线图片呢，急用。谢谢各位大虾。请给出详细的代码 --------------------编程问答--------------------
//输出图片改成
Response.ClearContent();
Response.ContentType = "image/Jpeg";
Response.BinaryWrite(ms.ToArray());
System.IO.MemoryStream ms = new System.IO.MemoryStream();或者你定义一个Image类型等于这个Fromstream --------------------编程问答--------------------
image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
//输出图片
return Image.FromStream(ms);
System.IO.MemoryStream ms = new System.IO.MemoryStream();直接保存下来 --------------------编程问答-------------------- 不是有报表控件吗 --------------------编程问答-------------------- System.IO.MemoryStream ms = new System.IO.MemoryStream();
image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
image.Save(string.Format("D:\\{0}.jpeg", filename), ImageFormat.Jpeg);
image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
image.Save(string.Format("D:\\{0}.jpeg", ms), System.Drawing.Imaging.ImageFormat.Jpeg);
这样写的话每次只能保存一次图片，如果图片存在的话运行的时候总是报错。 --------------------编程问答-------------------- 楼主，推荐你使用MSChar控件，使用简单、方便，基本不用你写代码，不过，net3.0版本以上才有。。。 --------------------编程问答-------------------- 那你先判断
if(!file.exist(string.Format("D:\\{0}.jpeg", filename)))则执行，否则名字得换。
--------------------编程问答--------------------
推荐zedgraph控件，开源＋免费＋实例
补充：.NET技术 , C#
