Windows Phone 7中的數組排序

Question

我想對我檢索的數據進行排序。 我有兩個數據時間和附加標題。 我能排序的時間。 但附註不符合排序安排。

例如，時間 - > 10:45 AM附標題 - >作業8:45 AM - >工作

時間排序 時間 8:45 AM作業 10:50 AM工作

Answer 1

的問題是，要排序的時間序列，但不是你的TI數組。 只需創建一個名爲Time，Title和Category的三個屬性的「ScheduleItem」類。然後創建一個強類型列表並在列表中進行排序。

你的類應該是這樣的

public class ScheduleItem : IComparable<ScheduleItem> 
{ 
    public DateTime Time { get; set; } 
    public string Title { get; set; } 
    public string Category { get; set; } 


    public int CompareTo(ScheduleItem item) 
    { 
     return Title.CompareTo(item.Title); 
    } 
} 

之後，你可以從你的文件中讀取你的價值觀和建立你的名單像這樣。

if (scheduleListBox.Items.Count == 0) 
{ 

    List<ScheduleItem> scheduleItems = new List<ScheduleItem>(); 
    for (int i = 0; i < timeSplit.Length; i++) 
    { 
     string timeList = timeSplit[i]; 
     string titleList = titleSplit[i]; 
     string categoryList = categorySplit[i]; 

     ScheduleItem item = new ScheduleItem 
           { 
            Time = DateTime.Parse(timeList), 
            Title = titleList, 
            Category = categoryList 
           }; 
     scheduleItems.Add(item); 

    } 

    scheduleItems.Sort(); 
} 

現在迭代您的ScheduleItems列表並構建您的控件。你的代碼應該看起來像這樣

if (scheduleListBox.Items.Count == 0) 
{ 

    List<ScheduleItem> scheduleItems = new List<ScheduleItem>(); 
    for (int i = 0; i < timeSplit.Length; i++) 
    { 
     string timeList = timeSplit[i]; 
     string titleList = titleSplit[i]; 
     string categoryList = categorySplit[i]; 

     ScheduleItem item = new ScheduleItem 
           { 
            Time = DateTime.Parse(timeList), 
            Title = titleList, 
            Category = categoryList 
           }; 
     scheduleItems.Add(item); 

    } 

    scheduleItems.Sort(); 

    foreach (ScheduleItem item in scheduleItems) 
    { 

     //Define grid column, size 
     Grid schedule = new Grid(); 
     //Column to hold the time of the schedule 
     ColumnDefinition timeColumn = new ColumnDefinition(); 
     GridLength timeGrid = new GridLength(110); 
     timeColumn.Width = timeGrid; 
     schedule.ColumnDefinitions.Add(timeColumn); 


     //Text block that show the time of the schedule 
     TextBlock timeTxtBlock = new TextBlock(); 
     timeTxtBlock.Text = item.Time; 
     //Set the alarm label text block properties - margin, fontsize 
     timeTxtBlock.FontSize = 28; 
     timeTxtBlock.Margin = new Thickness(0, 20, 0, 0); 
     //Set the column that will hold the time of the schedule 
     Grid.SetColumn(timeTxtBlock, 0); 
     schedule.Children.Add(timeTxtBlock); 



     //Column to hold the title of the schedule 
     ColumnDefinition titleColumn = new ColumnDefinition(); 
     GridLength titleGrid = new GridLength(300); 
     titleColumn.Width = titleGrid; 
     schedule.ColumnDefinitions.Add(titleColumn); 

     //Text block that show the title of the schedule 
     TextBlock titleTxtBlock = new TextBlock(); 
     titleTxtBlock.Text = item.Title; 

     if (item.Title.Length > 15) 
     { 
      string strTitle = item.Title.Substring(0, 15) + "...."; 
      titleTxtBlock.Text = strTitle; 
     } 
     else 
     { 
      titleTxtBlock.Text = item.Title; 
     } 
     //Set the alarm label text block properties - margin, fontsize 
     titleTxtBlock.FontSize = 28; 
     titleTxtBlock.Margin = new Thickness(20, 20, 0, 0); 
     //Set the column that will hold the title of the schedule 
     Grid.SetColumn(titleTxtBlock, 1); 
     schedule.Children.Add(titleTxtBlock); 



     //Column 3 to hold the image category of the schedule 
     ColumnDefinition categoryImageColumn = new ColumnDefinition(); 
     GridLength catImgnGrid = new GridLength(70); 
     categoryImageColumn.Width = catImgnGrid; 
     schedule.ColumnDefinitions.Add(categoryImageColumn); 

     //Text block that show the category of the schedule 
     TextBlock categoryTxtBlock = new TextBlock(); 
     categoryTxtBlock.Text = item.Category; 

     //set the category image and its properties - margin, width, height, name, background, font size 
     Image categoryImage = new Image(); 
     categoryImage.Margin = new Thickness(-20, 15, 0, 0); 
     categoryImage.Width = 50; 
     categoryImage.Height = 50; 
     if (categoryTxtBlock.Text == "Priority") 
     { 
      categoryImage.Source = new BitmapImage(new Uri("/AlarmClock;component/Images/exclamination_mark.png", UriKind.Relative)); 
     } 
     else 
      if (categoryTxtBlock.Text == "Favourite") 
      { 
       categoryImage.Source = new BitmapImage(new Uri("/AlarmClock;component/Images/star_full.png", UriKind.Relative)); 
      } 


     Grid.SetColumn(categoryImage, 2); 
     schedule.Children.Add(categoryImage); 
    } 

}
