File operations in C #

Read operation:

Method 1:

string str = File.readalltext (@filepath, Encoding.default);

Method 2:

byte [] buffer = file.readallbytes (@filepath); string str = Encoding.Default.GetString (buffer);

Method 3:

string [] buffer = file.readalllines (@filepath, encoding.default); string ""  ; foreach (var in  buffer) {    = str + buf +"\ n";}

Method 4:

New FileStream (@filepath, filemode.openorcreate); byte New byte [1024x7685]; int 0 , buffer. Length); string 0 , length); Fsread.close (); Fsread.dispose () ;

Method 5:

string str =""; using New FileStream (@filepath,    filemode.openorcreate,fileaccess.read)) {  bytenew  byte[1024x7685];   int 0 , buffer. Length);   0 , length);}

Write operation:

Method 1:

File.writealltext (@filepath, str, encoding.default);

Method 2:

byte [] buffer = Encoding.Default.GetBytes (str); File.writeallbytes (@filepath, buffer);

Method 3:

File.writealllines (@filepath, str. Split ('), Encoding.default);

Method 4:

New FileStream (@filepath, FileMode.OpenOrCreate, FileAccess.Write); byte [] buffer =0, buffer. Length); Fswrite.close (); Fswrite.dispose () ;

Method 5:

byte [] buffer = Encoding.Default.GetBytes (str); using New FileStream (@filepath, FileMode.OpenOrCreate, FileAccess.Write)) {  0, buffer. Length);}

Action folder:

CreateDirectory: Creating a Folder

Delete: Deleting a folder

Move: Cut Folder

Exist: Judging whether there is

GetFiles: Gets the full path of all files under the specified directory
