来自codeproject froums的例子是给..plz引用LineChart应用程序。但是用户使用webforms来显示最终图像...最后2行的apllication如下：

A separate class has been created for creating a graph..with all member functions.

Bitmap bmp = line2d.GetGraph();
bmp.Save(Response.OutputStream,ImageFormat.Jpeg);

推荐答案

Bitmap.Save方法接受流对象或者要保存位图的文件路径。

在最后一行代码中，如果要保存，请将Response.OutputSream替换为MemoryStream对象内存文件或传递临时文件路径，您可以在其中保存图像。

The Bitmap.Save method accepts the stream object or file path to which the bitmap is to be saved.
In your last line of code replace ''Response.OutputSream'' to MemoryStream object if you want to save in memory file or pass the temporary file path where you can save the image.
