C# Convert String to Byte Array and Byte Array to String

10th July 2008

By Tim Trott

These two methods allow conversion between a C# byte array and string, and vice versa. Handy in dealing with COM objects and some .Net Providers (IBM CWBX, EventLog and so on).

String to byte array

public static byte[] StrToByteArray(string str)
{
    System.Text.ASCIIEncoding  encoding = new System.Text.ASCIIEncoding();
    return encoding.GetBytes(str);
}

Byte array to string

public static string ByteArrayToStr(byte[] byteArray)
{
  System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();
  return encoding.GetString(byteArray);
}
