**C# changing over the binary string to int: Here, we will figure out how to change over a binary string to its comparable to an integer number in C#? **

Given a string that contains a binary value, we need to change over the binary string to an integer in C#.

### Changing over from binary string to int

To change over a given binary string into an integer, we use **Convert.ToInt32(String, Base/Int32)** technique.

### Syntax:

` Convert.ToInt32(String, Base/Int32);`

Here, String is a String object that ought to contain a binary value and Base/**Int32 **is an integer kind of item which determines the base of the information string.

Here, we are going to change over a binary string to an integer, and the base of the binary is 2. Subsequently, the value of Base **must be 2.**

## Example:

```
Input:
string bin_strng = "1100110001";
Function call:
Convert.ToInt32(bin_strng, 2);
Output:
817
Input:
string bin_strng = "10101010101010101010";
Function call:
Convert.ToInt32(bin_strng, 2);
Output:
699050
```

## C# code to change over a binary string to an integer

```
using System;
using System.Text;
namespace Test
{
class Program
{
static void Main(string[] args)
{
string bin_strng = "1100110001";
int number = 0;
number = Convert.ToInt32(bin_strng, 2);
Console.WriteLine("Number value of binary \"{0}\" is = {1}",
bin_strng, number);
bin_strng = "1111100000110001";
number = Convert.ToInt32(bin_strng, 2);
Console.WriteLine("Number value of binary \"{0}\" is = {1}",
bin_strng, number);
bin_strng = "10101010101010101010";
number = Convert.ToInt32(bin_strng, 2);
Console.WriteLine("Number value of binary \"{0}\" is = {1}",
bin_strng, number);
//hit ENTER to exit
Console.ReadLine();
}
}
}
```

## Output:

```
Number value of binary "1100110001" is = 817
Number value of binary "1111100000110001" is = 63537
Number value of binary "10101010101010101010" is = 699050
```
