How do I change a PictureBox's image?

问题

I have a program in C# with a PictureBox object inside a Form. How do I change its picture? The pictures to chose from are in bin/Pics; they are jpeg in format, if that matters..

回答1:

Assign a new Image object to your PictureBox's Image property. To load an Image from a file, you may use the Image.FromFile method. In your particular case, assuming the current directory is one under bin, this should load the image bin/Pics/image1.jpg, for example:

pictureBox1.Image = Image.FromFile("../Pics/image1.jpg");

Additionally, if these images are static and to be used only as resources in your application, resources would be a much better fit than files.

You can use the ImageLocation property of pictureBox1:

pictureBox1.ImageLocation = @"C:\Users\MSI\Desktop\MYAPP\Slider\Slider\bt1.jpg";
