C # obtain the MD5 value of an object,

[Convert] C # obtain the MD5 value of the file,

Private static string GetMD5HashFromFile (string fileName) {try {FileStream file = new FileStream (fileName, FileMode. open); System. security. cryptography. MD5 md5 = new System. security. cryptography. MD5CryptoServiceProvider (); byte [] retVal = md5.ComputeHash (file); file. close (); StringBuilder sb = new StringBuilder (); for (int I = 0; I <retVal. length; I ++) {sb. append (retVal [I]. toString ("x2");} return sb. toString ();} catch (Exception ex) {throw new Exception ("GetMD5HashFromFile () fail, error:" + ex. message );}}

Recently I was working on a resource docking project. The other party's interface asked us to pass the md5 value of the file. I searched for this method and recorded it.
