c# - Copy file into different folder directory name -

i create code copy don't know how combine copy code if filename not in jpeg,bmp,png or gif copy different folder name(c:\dump) if filename extension exists file copy (c:\destionation).

public static void copyfile( string[] args ) {     copyfolder( @"c:\source", @"c:\destination" );     console.readline(); }  static public void processdirectory(directoryinfo directory) {     foreach (fileinfo file in directory.enumeratefiles("*.jpg,*.bmp,*.png,*.gif,*.jpeg"))     {         //how combin process directory info copy folder statement//     } }  static public void copyfolder( string sourcedir, string destfolder ) {     if (!directory.exists( destfolder ))         directory.createdirectory( destfolder );     string[] files = directory.getfiles( sourcedir );     foreach (string file in files)     {         string name = path.getfilename( file );         string dest = path.combine( destfolder, name );         file.copy( file, dest);     } } 

you can compare extension of files with:

path.getextension(myfilepath);

for example, can add in code:

foreach (string file in files)     {         string name = path.getfilename( file );         string dest = path.combine( destfolder, name );         if(path.getextension(myfilepath) != "jpg" && path.getextension(myfilepath) !=  "bmp" && path.getextension(myfilepath) !=  "png" && path.getextension(myfilepath) !=  "gif" && path.getextension(myfilepath) !=  "jpeg"      ){         file.copy( file, dest);         }     } 

you can have reference in path.getextension method documentation.
