C # FileStream File replication

Method:

/// <summary>        ///file Copy/// </summary>        /// <param name= "source" >source files, for example: @ "D:\media\ copy. avi"</param>        /// <param name= "target" >destination file, for example: @ "D:\media\ copy. avi"</param>         Public voidFilestreamusecopy (stringSourcestringtarget) {            //The idea is to read the files that need to be copied and then write them to the established location .//to create a read stream            using(FileStream fsread=NewFileStream (Source,filemode.openorcreate,fileaccess.read)) {                //to create a write stream                using(FileStream fswrite=NewFileStream (Target,filemode.openorcreate,fileaccess.write)) {                    byte[] buffer =New byte[1024x768*1024x768*2]; intR=0; //r the number of bytes actually read this time                     while(R=fsread.read (Buffer,0, buffer.

To invoke the test:

Static voidMain (string[] args) {Program P=NewProgram (); //p.filestreamusewrite ();//Write//P.filestreamuseread (); //Read            stringSource =@"D:\20170220_Study\MyDone\media\8, using FileStream to achieve multimedia file replication. avi"; stringtarget =@"D:\20170220_Study\MyDone\media\new.avi";            P.filestreamusecopy (source, target); Console.WriteLine ("Replication succeeded");        Console.ReadLine (); }
