Visual C# Формат метки не показывает начальные нули в поле секунд

Question

Я изменяю программу с использованием Visual Studio 2015 и создал диаграмму с форматированием метки, заданным как:

this.chart1.ChartAreas [0] .AxisX.LabelStyle.Format = "mm: ss ";

Однако на некоторых значениях диаграмма отображается без начальных нулей. См. ниже; «3:07» отображается как «3: 7», et c. Я не волшебник c#, поэтому заранее спасибо за любую помощь!

        public string makeCharLabel(double chartTime)
    {
        string labelBuild;
        labelBuild = (((int)(chartTime)) - ((int)(chartTime / 60) * 60)).ToString();
        if (labelBuild == "0")
        {
            labelBuild = "00";
        }
        labelBuild = ((int)(chartTime/60)).ToString() + ":" + labelBuild;

        return labelBuild;
    }

        {

Поскольку ваши метки являются строками, форматирование не повлияет на них. Вы можете исправить ваш makeCharLabel для правильного форматирования при построении строки:

public string makeCharLabel(double chartTime) {
  int seconds = (((int)(chartTime)) - ((int)(chartTime / 60) * 60));
  int minutes = ((int)(chartTime / 60));
  return string.Format("{0:00}:{1:00}", minutes, seconds);
}
