I'm coming from a visual basic.net background. So....

What's the difference between = and == for example in vb.net I'd do this:

vb.net Code:
  1. If TextBox1.Text.Contains(".") = False Then

but in C# it's requiring me to do this:
c# Code:
  1. if (textbox1.text.containts(".") == False)

why's that?
