Converting a binary string to binary

Question

I have two string namely string1 and string2. they contain binary numbers and I want to manipulate them with different kinds of operations.

for example:

      string string1 = "1000";
      string string2 = "1011";

how can I Add/Subtract string1 and string2 so that:

      AnswerToAddtion = 10011               //1000 + 1011
      AnswerToSubtratction = 1101           //1000-1011

Same solution as: [convert a binary string-representation to a byte array](http://stackoverflow.com/questions/3436398/convert-a-binary-string-representation-to-a-byte-array) — Blachshma, Dec 04 '12 at 14:47

You can use Convert.ToInt32("11011",2); to parse your string to an integer value.

To convert an integer to a binary string, you can use Convert.ToString(myInt, 2);

@ChristopherRayl do you want the result of addition/subtraction in a string? The OP states they want to manipulate the values with different operations, and the problem is the data type is string. I think the solution is to use a more suiting data type. – Josh C. Dec 04 '12 at 15:15
I think he just wants to convert a binary string into a binary number so that he can perform binary arithmetic on it. – Christopher Rayl Dec 04 '12 at 15:17
@ChristopherRayl what difference should it make to do binary operations on an int32? What data type is a binary type? Int32 should be sufficient. If a binary string result is desired, generating the string is simple enough. – Josh C. Dec 04 '12 at 15:19
