c# example - convert stringbuilder to byte array
The following asp.net c# example code demonstrate us how can we convert a StringBuilder object to a byte
array programmatically at run time in an asp.net application. .Net framework's StringBuilder Class represent a
mutable string of characters. StringBuilder Class has no built in property or method to convert itself to a byte array.
But we can convert a String object to a byte array, so at first we need to convert a StringBuilder object's value to a String object. StringBuilder.ToString() method convert the value of this instance to a string.
.Net framework's ASCIIEncoding Class represents an ASCII character encoding of Unicode characters. ASCIIEncoding Class GetBytes(Char[]) overloaded method allow us to encode all the characters in the specified character array into a sequence of bytes.
This method require to pass a parameter named 'chars' which value type is System.Char[] and represent the character array containing the characters to encode. We can pass a string object as 'chars' parameter value of this method.
GetBytes(Char[]) method return value type is System.Byte[] which represent a byte array containing the results of encoding the specified set of characters. So, if we convert a StringBuilder object to a String and pass this string as parameter value of GetBytes(Char[]) method, then we can get a byte array.
