  STEP1: Introducing Libraries

1 using System.Security.Cryptography; 2 using System.IO;

STEP2: Computes the Md5 value of a string

1         Static  Public stringGetmd5withstring (stringSdatain)2         {3             stringstr ="";4             byte[] data = encoding.getencoding ("Utf-8"). GetBytes (str);5MD5 MD5 =NewMD5CryptoServiceProvider ();6             byte[] bytes =Md5.computehash (data);7              for(inti =0; I < bytes. Length; i++)8             {9str + = Bytes[i]. ToString ("X2");Ten             } One             returnstr; A}

STEP3: Calculating the MD5 value of a file

1         Static  Public stringGetmd5withfilepath (stringFilePath)2         {3FileStream file =NewFileStream (FilePath, FileMode.Open, FileAccess.Read, fileshare.read);4MD5CryptoServiceProvider MD5 =NewMD5CryptoServiceProvider ();5             byte[] Hash_byte =Md5.computehash (file);6             stringstr =System.BitConverter.ToString (hash_byte);7str = str. Replace ("-","");8             returnstr;9}
