C# Program to Convert a Binary String to an Integer Last Updated : 02 Jul, 2020 Comments Improve Suggest changes Like Article Like Report 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 integer using 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 integer using 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 Comment More infoAdvertise with us Next Article Convert Decimal to Binary in C S shivanisinghss2110 Follow Improve Article Tags : C# C# Programs Similar Reads C# Program to Find Binary Equivalent of an Integer using Recursion Given an integer number, now we convert the given integer number into a binary number using recursion.
