How do you convert a string such as "01110100011001010111001101110100" to a byte array then used File.WriteAllBytes such that the exact binary string is the binary of the file. In this case it would be the the text "test".

We can use String class getBytes() method to encode the string into a sequence of bytes using the platform's default charset. This method is overloaded and we can also pass Charset as argument. Here is a simple program showing how to convert String to byte array in java.
A String is stored as an array of Unicode characters in Java. To convert it to a byte array, we translate the sequence of characters into a sequence of bytes. For this translation, we use an instance of Charset. This class specifies a mapping between a sequence of chars and a sequence of bytes.
Byte arrays mostly contain binary data such as an image. If the byte array that you are trying to convert to String contains binary data, then none of the text encodings (UTF_8 etc.) will work.
In case you don't have this LINQ fetish, so common lately, you can try the normal way
string input .... int numOfBytes = input.Length / 8; byte[] bytes = new byte[numOfBytes]; for(int i = 0; i < numOfBytes; ++i) { bytes[i] = Convert.ToByte(input.Substring(8 * i, 8), 2); } File.WriteAllBytes(fileName, bytes); LINQ is great but there must be some limits.
