display image from the internet in a PictureBox (C#)

Hi all. Im trying to display images from the web into a picturebox control. when the form loads, i'd like for the pictureBox control to read a URL from a textbox control and load the image. i found the VB equivalent code to do this but im a newbie and cant translate it into C#:

PictureBox1.Image = New System.Drawing.Bitmap(New IO.MemoryStream(New System.Net.WebClient().DownloadData(TextBox1.Text)))  // Assumes there is a textbox called textbox1 and a picturebox called picturebox1 on a form. Textbox1.text should be the URL of the picture.

Is there an easier way to go about this? Any help is appreciated. Thanks in advance
