FileMD5 Class

FileMD5 is an object used to convert a file to a MD5 Checksum string. The name of this file is passed in during the construction of this object, or by using the property FileName. Then the Checksum is retrieved by using the Checksum property.

                using System.IO;

                namespace CustomTools.Examples
                {
                    public class MXF_Example
                    {
                        static void Main() 
                        {
                            // Read the name of the file to get the MD5 Checksum for
                            Console.Write("Enter the name of the file: ");
                            string file = Console.ReadLine();

                            // Create the MD5 Checksum object
                            FileMD5 hasher = new FileMD5( file );

                            // Print out the checksum result, if no error occurred
                            if ( !hasher.Error )
                                Console.WriteLine( "\n" + hasher.Checksum );
                            else
                                Console.WriteLine("\nError encountered during checksum");

                            // Wait for the user to hit enter
                            Console.WriteLine("\nHit Enter to Continue");
                            Console.ReadLine();
                        }
                    }
                }

This example will write the following to the Console Window:

	Copy
Enter the name of the file: E:\test.xml 8212ec9bec6d90d6002d256398790b83 Hit Enter to Continue
