我正在使用 Inno setup 来创建自定义安装程序，我需要它来向我的安装程序添加一些东西。通过这段代码，我可以找到文件的最后修改日期，但我想在运行设置时将文件名作为输入。看这里

GetFileAttributesEx('C:\Users\Gangadhar\Desktop\white_plain.gif', GetFileExInfoStandard , FileInformation);

在此函数中，我将文件名作为参数传递。我想在运行设置时选择此文件名，就像选择目标文件夹向导一样，然后将选定的文件名作为参数传递给上述函数。

任何帮助，将不胜感激。提前致谢

您正在寻找该GetOpenFileName函数，该函数显示一个对话框，使用户能够选择现有文件。以下脚本显示了当用户离开欢迎页面时如何显示此对话框。如果用户取消文件选择，他们将停留在欢迎页面：

[Code]
function NextButtonClick(CurPageID: Integer): Boolean;
var
  FileName: String;
begin
  // allow users to go through the wizard by default
  Result := True;
  // if the user is going to leave the welcome page, then... 
  if CurPageID = wpWelcome then
  begin
    // set the initial file name
    FileName := '';
    // open the file dialog; if the user cancels it, they will stay at
    // the welcome page (I don't know if it's your intention though)
    Result := GetOpenFileName('Select the file to check', FileName, '',
      'GIF Files (*.gif)|*.gif|All Files|*.*', '');
    // if the user selected a file, then do whatever you want with it
    if Result then
    begin
      // you got the file name in FileName variable
    end;
  end;  
end;
