Converting string to binary?

Question

Hi I am converting int values to string with binary mode like below; string aa = Convert.ToString(128 2); But I want to convert a string value to binary. How can I do that? String aa = 11101010;

If you mean that you want to convert a binary string to an integer then try: String aa = 11101010; int i = Convert.ToInt32(aa 2); Console.WriteLine(i); // 234

The below code helps you to do conversion of string into binary. string strText = Hello; byte[] btText; btText = System.Text.Encoding.UTF8.GetBytes(strText); Array.Reverse(btText); BitArray bit = new BitArray(btText); StringBuilder sb = new StringBuilder(); for (int i = bit.Length - 1; i >= 0; i--) { if (bit[i] == true) { sb.Append(1); } else { sb.Append(0); } } Label1.Text = sb.ToString();
