新建文件

• 添加文件［类型：用户控件］

  ./Common/Models/TaskBars.cs

  ./Common/Models/ToDoDto.cs

  ./Common/Models/MemoDto.cs

新建类

TaskBars.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace Mytodo.Common.Models
{public class TaskBar{private string? title;private string? content;private string? target;private string? color;private string? icon;public string? Icon{get { return icon; }set { icon = value; }}public string? Title{get { return title; }set { title = value; }}public string? Content{get { return content; }set { content = value; }}public string? Color{get { return color; }set { color = value; }}public string? Target{get { return target; }set { target = value; }}}
}

TodoDto.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace Mytodo.Common.Models
{public class ToDoDto:BaseTodo{private string? title;private string? content;private int status;public int Status{get { return status; }set { status = value; }}public string? Content{get { return content; }set { content = value; }}public string? Title{get { return title; }set { title = value; }}}
}

MemoDto.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace Mytodo.Common.Models
{/// <summary>/// 备忘录/// </summary>public class MemoDto:BaseTodo{private string? title;private string? content;private int status;public int Status{get { return status; }set { status = value; }}public string? Content{get { return content; }set { content = value; }}public string? Title{get { return title; }set { title = value; }}}
}

BaseTodo.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace Mytodo.Common.Models
{public   class BaseTodo{private int id;private DateTime createDate;private DateTime updateDate;/// <summary>/// 项修改日期/// </summary>public DateTime UpdateDate{get { return updateDate; }set { updateDate = value; }}/// <summary>/// 项创建时间/// </summary>public DateTime CreateDate{get { return createDate; }set { createDate = value; }}/// <summary>/// 项ID/// </summary>public int Id{get { return id; }set { id = value; }}}
}

创建TaskBars集合变量并初始化

创建变量

• IndexViewModel

  private ObservableCollection<TaskBar> taskBars;
  

初始化

• IndexViewModel（代码在构造函数中）

TaskBars=new ObservableCollection<TaskBar>();
TaskBars.Add(new TaskBar { Icon = "CalendarBlankOutline", Title = "汇总", Color = "#FF00FF00", Content = "27", Target = "" });
TaskBars.Add(new TaskBar { Icon = "CalendarMultipleCheck", Title = "已完成", Color = "#6B238E", Content = "24", Target = "" });
TaskBars.Add(new TaskBar { Icon = "ChartLine", Title = "完成比例", Color = "#32CD99", Content = "100%", Target = "" });
TaskBars.Add(new TaskBar { Icon = "CheckboxMarked", Title = "备忘录", Color = "#5959AB", Content = "13", Target = "" });

创建todoDtos、memoDtos集合变量并初始化

• IndexViewModel

  private ObservableCollection<ToDoDto> todoDtos;
  private ObservableCollection<MemoDto> memoDtos;
  public ObservableCollection<MemoDto> MemoDtos
  {get { return memoDtos; }set { memoDtos = value; RaisePropertyChanged(); }
  }public ObservableCollection<ToDoDto> TodoDtos
  {get { return todoDtos; }set { todoDtos = value; RaisePropertyChanged(); }
  }
  void CreatTestData()
  {TodoDtos = new ObservableCollection<ToDoDto>();MemoDtos = new ObservableCollection<MemoDto>();for (int i = 0; i < 20; i++){TodoDtos.Add(new ToDoDto() { Title = "待办" + i, Content = "正在处理中....." });MemoDtos.Add(new MemoDto() { Title = "备忘" + i, Content = "正在忘记中....." });}
  }
  public IndexViewModel()
  {Title = "您好，2022";TaskBars=new ObservableCollection<TaskBar>();TaskBars.Add(new TaskBar { Icon = "CalendarBlankOutline", Title = "汇总", Color = "#FF00FF00", Content = "27", Target = "" });TaskBars.Add(new TaskBar { Icon = "CalendarMultipleCheck", Title = "已完成", Color = "#6B238E", Content = "24", Target = "" });TaskBars.Add(new TaskBar { Icon = "ChartLine", Title = "完成比例", Color = "#32CD99", Content = "100%", Target = "" });TaskBars.Add(new TaskBar { Icon = "CheckboxMarked", Title = "备忘录", Color = "#5959AB", Content = "13", Target = "" });CreatTestData();
  }
