Visual C# 2005 (5 stars programmer)

[Luis Moises Rojas]

I am doing an example in C# 2005 (Express Edition, I am doing microsoft 5 stars programmer course).
The first star has the following example with a WebBrowser Control.

webBrowser1.Url(txtUrl.Text.Trim);

Very simple. Read a textbox an pass the address to the webbrowser control, accourding to the course it should work. But the sinxtax says that is it a propoerty. Any hlp?
