c # Select File dialog box

 

 Because the Open and Save inherited from FileDialog same, he made a general method.

        // default open path 
        Private  String the InitialDirectory = " D: \\ " ;
         // unified box 
        Private  BOOL InitialDialog (the FileDialog fileDialog, String title) 
        { 
            fileDialog.InitialDirectory = the InitialDirectory; // initialize path 
            fileDialog.Filter = " TXT Files ( .txt *, * *) | * .txt;. * *. " ; // filtering options settings, text file, all files. 
            = fileDialog.FilterIndex . 1 ; // currently using the second filter string 
            fileDialog.RestoreDirectory = to true ;// restore the original directory when the dialog is closed 
            fileDialog.Title = title;
             IF (fileDialog.ShowDialog () == to true ) 
            { 
                for ( int I = . 1 ; I <= fileDialog.FileName.Length; I ++ ) 
                { 
                    IF (fileDialog. FileName.Substring (fileDialog.FileName.Length -i, . 1 ) .Equals ( @ " \ " )) 
                    { 
                        // change the default path to the most recently opened path 
                        the InitialDirectory fileDialog.FileName.Substring = ( 0 , fileDialog.FileName.Length - I + 1);
                        return true;
                    }
                }

                return true;
            }
            else
            {
                return false;
            }

            IF (InitialDialog (OpenFileDialog, " the Open " )) 
            { 
                the using (Stream Stream = openFileDialog.OpenFile ()) 
                { 
                    FileName = (( System.IO.FileStream) Stream) .Name;
                     // perform operations related documents 
　　　　　　　　　　　　... 
                } 
            }

                     // perform a save operation
