重写一个字符串分割函数 - 回复 "tomzw" 的问题

---

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

{分割字符串的函数, 其实是个过程}
procedure Split(const str: string; const c: Char; var List: TStrings);
begin
  List.Clear;
  List.Delimiter := c;
  List.DelimitedText := str;
end;

{调用测试}
procedure TForm1.Button1Click(Sender: TObject);
var
  List: TStrings;
  s: string;
  c: Char;
begin
  s := 'aaa;bbb;ccc;ddd';
  c := ';';

  List := TStringList.Create;
  Split(s,c,List);
  ShowMessage(List[1]); {bbb}
  List.Free;
end;

end.
