【经验】Delphi INI文件保存与读取

//需要引用IniFiles
uses
  system.IniFiles;

//保存INI配置文件
procedure TForm1.btnSaveClick(Sender: TObject);
var
  myIniFile: TIniFile;
  filepath: string;
begin
  filepath := ExtractFilePath(Application.Exename) + ‘DBConfig.ini‘; //取得ini文件的路径
  myIniFile := TIniFile.Create(filepath);
  try
    myIniFile.WriteString(‘DBConf‘, ‘Server‘, edtServer.Text);     //服务器地址
    myIniFile.WriteString(‘DBConf‘, ‘Port‘, edtPort.Text);         //数据库端口
    myIniFile.WriteString(‘DBConf‘, ‘Database‘, edtDatabase.Text); //数据库名
    myIniFile.WriteString(‘DBConf‘, ‘User‘, edtUser.Text);         //登录用户名
    myIniFile.WriteString(‘DBConf‘, ‘Password‘, edtPwd.Text);      //登录密码
    ShowMessage(‘保存成功‘);
  finally
    myIniFile.Free;
  end;
end;

 

//载入INI配置文件
procedure TForm1.btnLoadClick(Sender: TObject);
var
  myIniFile: TIniFile;
  filepath: string;
begin
  filepath := ExtractFilePath(Application.Exename) + ‘DBConfig.ini‘; //取得ini文件的路径
  myIniFile := TIniFile.Create(filepath);
  try
    ListBox1.Clear;
    ListBox1.Items.Add(‘服务器:‘ + myIniFile.ReadString(‘DBConf‘, ‘Server‘, ‘‘));     //服务器地址
    ListBox1.Items.Add(‘端口:‘ + myIniFile.ReadString(‘DBConf‘, ‘Port‘, ‘‘));         //数据库端口
    ListBox1.Items.Add(‘数据库:‘ + myIniFile.ReadString(‘DBConf‘, ‘Database‘, ‘‘));   //数据库名
    ListBox1.Items.Add(‘用户名:‘ + myIniFile.ReadString(‘DBConf‘, ‘User‘, ‘‘));       //登录用户名
    ListBox1.Items.Add(‘密码:‘ + myIniFile.ReadString(‘DBConf‘, ‘Password‘, ‘‘));     //登录密码
  finally
    myIniFile.Free;
  end;
end;
