Loading image from a server into a Picturebox.

Hello guys, are you okay? I hope very well!

Most of our projects need to load images from a server, be it an advertisement, a new software update, or other needs. For this project, we will need the components below.

- PictureBox;

- Button;

- TextField.

Organize your project layout as shown below.

Now double-click the button and enter the algorithm shown below.

Code 01

WebRequest request = WebRequest.Create(txtLoad.Text); //Initializes an instance with the given URL
            using (var response = request.GetResponse()) //Tries to access the object
            {
                using (var str = response.GetResponseStream()) //Returns the metadata of the image
                {
                    pcbImage.Image = Bitmap.FromStream(str); //Creates a bitmap based on the loaded metadata, in the sequence inserts into the image property.
                }
}

Remember to import the System.NET class.
