概述
前几天群里有人问如何制作备忘录,感觉这样一个小实例挺适合新手们入门学习使用,所以就抽空做了出来。界面如下图:
这个备忘录主要包括了如下功能:
① 备忘录信息的增、删、改、查;
② 备忘录时间到了以后进行语音播报。
功能很简单,但是要实现这么一个功能,也涉及众多的知识点,接下来详细进行分解。

内容详述
①界面button的图标:
图标图片可以上网上下载,下载好以后放到项目目录中,然后在项目中找到你的图片——>右键包括在项目中——>再右键,点击属性:
复制到输出目录,更改为始终复制。
生成操作,更改为内容。
前台XMAL操作:
<Button Margin="15,5" MinWidth="60" cal:Message.Attach="[Event Click] = [Action SearchClick]" ><WrapPanel ><Image Source="/Images/search.png" Width="15" Height="15" /><TextBlock Text="查找" VerticalAlignment="Center" /></WrapPanel></Button>
② 数据源:这里我采用从xml读取并绑定到界面,界面如果有修改,在页面退出时进行数据保存,当然你也可以使用数据库去操作
XML文件位置:根目录的RawData下
XML文件数据内容如下:
MemorandumModel数据模型定义:
public class MemorandumModel {public string Title { get; set; }public EvenType EvenType { get; set; }public DateTime DateTime { get; set; }public bool IsComplete { get; set; }}
③XML文件的读取和保存:MemorandumRealList是我们所有数据的集合,为了方便界面查询,界面绑定了MemorandumShowList 这个集合
xml读取:
public void XmlDocReader(){//XmlDocument读取xml文件XmlDocument xmlDoc = new XmlDocument();xmlDoc.Load(XmlDocPath);//获取xml根节点XmlNode xmlRoot = xmlDoc.DocumentElement;if (xmlRoot == null)return;//读取所有的节点foreach (XmlNode node in xmlRoot.SelectNodes("MemorandumModel")){MemorandumRealList.Add(new MemorandumModel(){Title = node.SelectSingleNode("Title").InnerText,EvenType = (EvenType)Enum.Parse(typeof(EvenType), node.SelectSingleNode("EvenType").InnerText),DateTime = Convert.ToDateTime(node.SelectSingleNode("DateTime").InnerText),IsComplete = Convert.ToBoolean(node.SelectSingleNode("IsComplete").InnerText)}); }MemorandumShowList = new ObservableCollection<MemorandumModel>(MemorandumRealList);}
xml文件保存:
public void SaveXmlDoc(){//获取根节点对象XDocument document = new XDocument();XElement xmlRoot = new XElement("MemorandumModels");XElement memorandumModel;foreach (var memorandumReal in MemorandumRealList){memorandumModel = new XElement($"MemorandumModel");memorandumModel.SetElementValue("Title", memorandumReal.Title);memorandumModel.SetElementValue("EvenType", memorandumReal.EvenType);memorandumModel.SetElementValue("DateTime", memorandumReal.DateTime);memorandumModel.SetElementValue("IsComplete", memorandumReal.IsComplete);xmlRoot.Add(memorandumModel);}xmlRoot.Save(XmlDocPath);}
④查询:如果全选选中,则显示全部内容,未勾选,则采用link去匹配选中信息去筛选,我这里是所有信息去匹配的,你也可以自己修改下,去只匹配某一项或几项内容
public void SearchClick(){SaveXmlDoc();if (SelectAll){MemorandumShowList = new ObservableCollection<MemorandumModel>(MemorandumRealList);return;}MemorandumShowList = new ObservableCollection<MemorandumModel>(MemorandumRealList.Where(t => t.EvenType == EvenTypeList[SelectedIndex]).Where(s => s.IsComplete == IsCompleteStatus).Where(p => p.Title == TitleText).Where(x => x.DateTime == DateTime.Parse(DataTimeContext)) .ToList() );}
⑤标题栏未输入内容时显示灰色提示字体,有输入时输入内容显示黑色字体:
这里采用事件处理:获取到光标时
public void LostFocus(){if (string.IsNullOrEmpty(TitleText)){TitleText = "备忘录标题";TitleColor = Color.DimGray;}}
光标离开时:
public void GotFocus(){TitleText = "";TitleColor = Color.Black;}
⑥选中行删除:
public void DeleteClick(){MemorandumRealList.Remove(SelectedItem);MemorandumShowList.Remove(SelectedItem);}
⑦行号获取:在行选择改变事件中去做
public void GridControl_SelectedItemChanged(object sender, SelectedItemChangedEventArgs e){GridControl gd = sender as GridControl;SelectRow = gd.GetSelectedRowHandles()[0];//选中行的行号}
⑧添加信息:
public void Add(){MemorandumRealList.Add(new MemorandumModel(){Title = titleText,DateTime =DateTime.Parse(DataTimeContext),EvenType = EvenTypeList[SelectedIndex],IsComplete = IsCompleteStatus});MemorandumShowList.Add(new MemorandumModel(){Title = titleText,DateTime = DateTime.Parse(DataTimeContext),EvenType = EvenTypeList[SelectedIndex],IsComplete = IsCompleteStatus});}
⑨修改信息:
public void Modify(){MemorandumRealList[SelectRow] = new MemorandumModel(){Title = titleText,DateTime = DateTime.Parse(DataTimeContext),EvenType = EvenTypeList[SelectedIndex],IsComplete = IsCompleteStatus};MemorandumShowList[SelectRow] = new MemorandumModel(){Title = titleText,DateTime = DateTime.Parse(DataTimeContext),EvenType = EvenTypeList[SelectedIndex],IsComplete = IsCompleteStatus};}
⑩定时器查询:采用using System.Threading.Tasks;下的单线程定时器DispatcherTimer,
定义和初始化:
private DispatcherTimer timer;timer = new DispatcherTimer();timer.Interval = TimeSpan.FromMinutes(1);timer.Tick += timer1_Tick;timer.Start();
定时器事件:我这里每隔一分钟查询一次,查询到当前事件到了提醒时间就进行一次语音播报:
private void timer1_Tick(object sender, EventArgs e){foreach (var memorandum in MemorandumRealList){if(DateTime.Now >= memorandum.DateTime){SpeakAsync(memorandum.Title);}}}
⑩①:语音播报:这里开了task线程执行
/// <summary>/// 微软语音识别/// </summary>/// <param name="content">提示内容</param>public static void SpeakAsync(string content){try{Task.Run(() =>{SpVoice voice = new SpVoice();voice.Rate = 1;//速率[-10,10]voice.Volume = 10;//音量[0,100]voice.Voice = voice.GetVoices().Item(0);//语音库voice.Speak(content);});}catch (Exception ex){throw ex;}}
⑩② 界面时间处理:
界面的表格采用的dev控件gridcontrol,默认情况下,时间只显示年月日,如果需要显示时分,需要设定:EditSettings如下
<dxg:GridColumn Header="提醒时间" FieldName="DateTime" MinWidth="120" ><dxg:GridColumn.EditSettings><!--<xctk:DateEditSettings DisplayFormat="dd-MM-yyyy HH:mm:ss.fff"/>--><xctk:DateEditSettings DisplayFormat="yyyy-MM-dd HH:mm"/></dxg:GridColumn.EditSettings></dxg:GridColumn>
如果使用的是wpf 自带的表格控件datagrid,相对好处理
<DataGridTextColumn Header="提醒时间" Binding="{Binding Path=DateTime,StringFormat='yyyy年MM月dd日 HH:mm:ss'}" MinWidth="300" />
界面顶端的时间控件采用:toolkit下的xctk1:DateTimeUpDown这个控件
她绑定的是一个字符串类型的数据,所以添加时候,需要将他转换为datetime类型, DateTime.Parse(DataTimeContext),或者
DateTime = Convert.ToDateTime(DataTimeContext)
<xctk1:DateTimeUpDown x:Name="_minimum" Format="Custom" FormatString="yyyy/MM/dd HH:mm" Text="{Binding DataTimeContext}" HorizontalAlignment="Left" VerticalAlignment="Center"Value="2016/01/01T12:00" Margin="15,5"/>
⑩③combobox枚举内容绑定:
public ObservableCollection<EvenType> EvenTypeList { get; set; } = new ObservableCollection<EvenType>();
foreach (EvenType evenType in Enum.GetValues(typeof(EvenType))){EvenTypeList.Add(evenType);}
⑩④关于gridcontrol TableView 的常用属性介绍
TableView 的常用属性:AllowPerPixelScrolling //逐像素滚动;
AllowScrollAnimation //滚动动画,当下拉滚动条时有动画效果
NavigationStyle //选中方式是一行还是单元格
ShowIndicator //是否在每一行之前显示小方块
UseEvenRowBackground //隔行其背景颜色会有所区分
AllowScrollToFocusedRow //允许滚动到选中行
AllowResizing //允许调整尺寸
AllowSorting //允许排序
AutoWidth //允许自动调整列宽
AllowMoveColumnToDropArea //允许将一列拖到空白处进行分组
AllowGrouping //允许分组
AllowFilterEditor //允许显示过滤盘
AllowEditing //允许编辑
ShowGroupPanel//显示分组panel
ShowHorizontalLines ShowVerticalLines //显示表格中每行每列垂直和水平线
IsColumnMenuEnabled //是否关闭右键列菜单
