How to convert a string to system.drawing.fontfamily

I'm reading a string from a text file and placing it in a variable called "myString"
Now, I want to take this string and make it the font name of a label, but I'm having a problem converting this string to System.Drawing.FontFamily.

I've tried this, but it doesn't work

.NET Code:

CType(myString, System.Drawing.FontFamily)

What do I do?

try this:

vb Code:

Dim ff As New FontFamily("Arial")
