# Binary to decimal using C#

CsharpServer Side ProgrammingProgramming

To convert binary to decimal, here I have used a while loop and found the remainder of the Binary number, which is the input. After that, the remainder is multiplied by the base value and added.

This is what I did to get the decimal value −

while (val > 0) {
remainder = val % 10;
myDecimal = myDecimal + remainder* baseVal;
val = val / 10;
baseVal = baseVal * 2;
}

## Example

Let us see the complete code to convert binary to decimal in C# −

class toBinary {
static void Main(string[] args) {
int val = 1010, myBinary, remainder;
int myDecimal = 0, baseVal = 1;
myBinary = val;
while (val > 0) {
remainder = val % 10;
myDecimal = myDecimal + remainder * baseVal;
val = val / 10;
baseVal = baseVal * 2;
}
Console.Write("Binary Number : " + myBinary);
Console.Write("\nConverted to Decimal: " + myDecimal);
}
Binary Number : 1010
Converted to Decimal: 10
