一組檔案名稱(主要以數字命名), 我想按數字大小排序

uses System.IOUtils, System.Types, System.Generics.Collections, System.Generics.Defaults, System.Character;procedure StrArrNumberSort(var Arr: TArray<string>);begin  TArray.Sort<string>(Arr,    TComparer<string>.Construct(      function (const s1,s2: string): Integer      var        L1,L2: string;      begin        L1 := TPath.GetFileNameWithoutExtension(s1);        L2 := TPath.GetFileNameWithoutExtension(s2);        if (IsDigit(L1[1]) and IsDigit(L2[1])) then          Result := StrToIntDef(L1, 0) - StrToIntDef(L2, 0)        else          Result := CompareText(L1, L2);        {考慮嵌套目錄}        L1 := TPath.GetDirectoryName(s1);        L2 := TPath.getDirectoryName(s2);        Result := CompareText(L1, L2) * MaxWord + Result;      end    )  );end;procedure TForm1.Button1Click(Sender: TObject);var  arr: TArray<string>;  s: string;begin  arr := TArray<string>(TDirectory.GetFiles('c:\temp'));  StrArrNumberSort(arr);  for s in arr do Memo1.Lines.Add(s);end;
