File stream read/write

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.IO;namespace_09 file Stream {classProgram {Static voidMain (string[] args) {            //string msg = "3,000 feet straight down";            ////String to byte array            //byte[] buffer = System.Text.Encoding.UTF8.GetBytes (msg);            ////byte array to string            //string str= System.Text.Encoding.UTF8.GetString (buffer); //writes a string to a file, writes the content in a stream//using (FileStream fs = new FileStream ("1.txt", FileMode.Create, FileAccess.Write))//{            //string msg = "The text can be a pen to control Lori"; //byte[] buffer = System.Text.Encoding.UTF8.GetBytes (msg); //FS. Write (buffer, 0, buffer.            Length); //}//Console.readkey (); //FS. Close ();//Close the stream//FS. Flush ();//Clear Buffer//FS. Dispose ();//frees up the resources that are occupied (these three must be written together, using the same method instead of the three freed resources)//read data in a streaming way            using(FileStream fs =NewFileStream ("1.txt", FileMode.Open, FileAccess.Read)) {                byte[] buffer =New byte[FS.                Length]; Fs. Read (Buffer,0, buffer.                Length); stringmsg =System.Text.Encoding.UTF8.GetString (buffer);            Console.WriteLine (msg);        } console.readkey (); }    }}

Large file movement

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.IO;namespace_10 Large file Move {classProgram {Static voidMain (string[] args) {            //Read the stream            using(FileStream fsread=NewFileStream (@"g:\ video \ Pirate. mkv", FileMode.Open, FileAccess.Read)) {                //Write the Stream                using(FileStream fswrite=NewFileStream (@"g:\ movie \ Pirate. mkv", FileMode.Create, FileAccess.Write)) {                    //the size of each read is 5M                    byte[]buffer=New byte[1024x768*1024x768*5]; //actual (the size actually read to)                   intR= fsread.read (Buffer,0, buffer.                   Length);  while(r>0)                   {                       //WriteFswrite.write (Buffer,0, R); Console.WriteLine ("**"); //re-readr = Fsread.read (buffer,0, buffer.                   Length); }}} Console.WriteLine ("Okay, OK.");        Console.readkey (); }    }}

Another way to read and write

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.IO;namespace_11 Another way of reading and writing {classProgram {Static voidMain (string[] args) {            #regionReading data//using (StreamReader reader = new StreamReader ("1.txt", Encoding.default))//{            //only one row was read//string msg= Reader.            ReadLine (); //string msg; //to Loop Read//While ((Msg=reader. ReadLine ())!=null)//{            //Console.WriteLine (msg); //}            //always read to the end of the stream//string msg= Reader.            ReadToEnd (); //Console.WriteLine (msg); //While (!reader. Endofstream)//{            //Console.WriteLine (reader.            ReadLine ()); //}            // }             #endregion            #regionWrite Data//using (StreamWriter write=new StreamWriter ("One.txt"))//{            //write.            Write ("This can be the same"); //}            #endregion           //Console.readkey ();                   }    }}
