C# Program to Convert a Binary String to an Integer

• Last Updated : 02 Jul, 2020

Given an binary string as input, we need to write a program to convert the binary string into equivalent integer. To convert an binary string to integer, we have to use Convert.ToInt32(String, Base/Int32) function to convert the values. The base of the binary is 2.

Syntax:

Convert.ToInt32(String, Base/Int32);

Examples:

Input  : 1010101010101010
Output : 43690

Input : 1100011000
111100001111
11001100110011001100

Output : 792
3855
838860

Program 1:

csharp

 // C# program to convert array// of binary string to an integerusing System;using System.Text;  class GFG {      static void Main(string[] args)    {        // binary number as string        string bin_strng = "1010101010101010";        int number = 0;                // converting to integer        number = Convert.ToInt32(bin_strng, 2);                // to print  the value        Console.WriteLine("Number value of binary \"{0}\" is = {1}", bin_strng,                          number);    }}

Output:

Number value of binary "1010101010101010" is = 43690

Program 2:

C#

 // C# program to convert array// of binary string to an integerusing System;using System.Text;  namespace geeks {class GFG {        static void Main(string[] args)    {        // binary number as string        string bin_strng = "1100011000";        int number = 0;          // converting to integer        number = Convert.ToInt32(bin_strng, 2);                // to print  the value        Console.WriteLine("Number value of binary \"{0}\" is = {1}", bin_strng,                          number);          bin_strng = "111100001111";          // converting to integer        number = Convert.ToInt32(bin_strng, 2);                // to print  the value        Console.WriteLine("Number value of binary \"{0}\" is = {1}", bin_strng,                          number);          bin_strng = "11001100110011001100";          // converting to integer        number = Convert.ToInt32(bin_strng, 2);                // to print the value        Console.WriteLine("Number value of binary \"{0}\" is = {1}", bin_strng,                          number);          // hit ENTER to exit        Console.ReadLine();    }}}

Output:

Number value of binary "1100011000" is = 792
Number value of binary "111100001111" is = 3855
Number value of binary "11001100110011001100" is = 838860
