十三、详测 Generics Collections TList (4): AddRange、InsertRange、DeleteRange-优快云博客

本文介绍了一个使用Delphi实现的泛型集合（TList<Byte>）的基本操作示例，包括创建、添加元素、插入范围、删除范围等，并通过消息框展示每个步骤后的集合状态。

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

uses
  Generics.Collections;

procedure TForm1.Button1Click(Sender: TObject);
var
  List, ListTmp: TList<Byte>;
  i: Byte;
  str: string;
begin
  List := TList<Byte>.Create;
  List.AddRange([11,22,33]);  //AddRange
  str := '';
  for i in List do str := str + IntToStr(i) + ' ';
  ShowMessage(str);

  ListTmp := TList<Byte>.Create;
  ListTmp.AddRange([44,55]);
  List.AddRange(ListTmp);
  str := '';
  for i in List do str := str + IntToStr(i) + ' ';
  ShowMessage(str);
  List.InsertRange(1, ListTmp);  //InsertRange
  str := '';
  for i in List do str := str + IntToStr(i) + ' ';
  ShowMessage(str);
  List.DeleteRange(1,3);  //DeleteRange
  str := '';
  for i in List do str := str + IntToStr(i) + ' ';
  ShowMessage(str);
  ListTmp.Free;
  List.Free;
end;

end.
