Load and save bitmaps using dotnet

Question

This may be simple one, but 5 mins of Googling didn't give me the answer. How do you save and load bitmaps using .Net librabries?

I have an Image object and I need to save it to disk in some format (preferably png) and load back in later. A C# example would be great.

Answer 1

About 10 seconds of google lead me to this example for the save method, you can dig around a bit more for the others.

Answer 2

Here's a really simple example.

Top of code file

using System.Drawing;

In code

Image test = new Bitmap("picture.bmp");
test.Save("picture.png", System.Drawing.Imaging.ImageFormat.Png);

Remember to give write permissions to the ASPNET user for the folder where the image is to be saved.

Answer 3

Hiya, use the Image.Save() method.

A better explanation and code sample than I could provide can be found here:
