The

Parse( )

 methods will throw a 

FormatException

 if 

str

 does not contain a valid 

number as defined by the invoking type. 

ArgumentNullException

 is thrown if 

str

 is null, and 

OverflowException

 is thrown if the value in 

str

 exceeds the bounds of the invoking type.

The parsing methods give you an easy way to convert a numeric value, read as a string 

from the keyboard or a text file, into its proper internal format. For example, the following
