You have a string containing a number in base2 (binary), base8 (octal), base10 (decimal), or base16 (hexadecimal). You need to convert this string to its equivalent integer value and display it in base10.
Use the overloaded static
Convert.ToInt32
method on the
Convert
class:
string base2 = "11"; string base8 = "17"; string base10 = "110"; string base16 = "11FF"; Console.WriteLine("Convert.ToInt32(base2, 2) = " + Convert.ToInt32(base2, 2)); Console.WriteLine("Convert.ToInt32(base8, 8) = " + Convert.ToInt32(base8, 8)); Console.WriteLine("Convert.ToInt32(base10, 10) = " + Convert.ToInt32(base10, 10)); Console.WriteLine("Convert.ToInt32(base16, 16) = " + Convert.ToInt32(base16, 16));
This code produces the following output:
Convert.ToInt32(base2, 2) = 3 Convert.ToInt32(base8, 8) = 15 Convert.ToInt32(base10, 10) = 110 Convert.ToInt32(base16, 16) = 4607
The static Convert.ToInt32
method has an overload
that takes a string containing a number and an integer defining the
base of this number. This method then converts the numeric string
into an integer and returns this number displayed as base10.
The other static methods of the Convert
class,
such as ToByte
, ToInt64
, and
ToInt16
, also have this same overload, which
accepts a number as a string and a base type for this number.
Unfortunately, these methods convert from base2, base8, base10, and
base16 only to a value of base10. They do not convert a value to any
other base types.
