C# - How to save images from a dictionary<string, images> to a folder

Question

I am currently working on a 2D Game Engine, so far I have added a feature to load and remove images, but now I want to save them, this is the dictionary:

public Dictionary<string, Image> images = new Dictionary<string, Image>();

The string is the name, for example when the person wants to add an image they click a button that says choose image then a pitcurebox will be set as the image that was opened, then there is a textbox, when they click a button that says Add Image, it will do this images.Add(textBox1.Text, pictureBox1.Image) Then I want to save all the images added to a folder

I have looked all over the internet for this, but no one has an answer for me, and I'm really stuck, thanks in advance.

Answer 1

The Image class has the Save method. So you could do something like this:

foreach (var imgX in images.Select(kvp => kvp.Value))
{
    imgX.Save("figure_a_file_path_and_name", ImageFormat.Jpeg);
}

UPDATE

If you would like to use the string in the dictionary as file name change the above code a little bit:

var folder = "figure_the_folder_path\\";

foreach (var entry in images)
{
    var destinationFile = string.Concat(folder, entry.Key); 
    var img = entry.Value;
    img.Save(destinationFile, ImageFormat.Jpeg);
}
