private set; }public string Spectr { get; private set; }public double Luminocity { get; private set; }public double ColorIndex { get; private set; }public double X { get; private set; }public double Y { get; private set; }public double Z { get; private set; }public Star(int id,double x,double y,double z,string spectr, double luminocity, double colorIndex) {HipID id;X x;Y y;Z z;Spectr spectr;Luminocity luminocity;ColorIndex colorIndex;}}}VB.NETPublic Class StarDim mHipID As Int32Dim mSpectr As StringDim mX, mY, mZ, mLuminocity, mColorIndex As DoublePublic ReadOnly Property HipID() As Int32GetReturn mHipIDEnd GetEnd PropertyPublic ReadOnly Property Spectr() As StringGetReturn mSpectrEnd GetEnd PropertyPublic ReadOnly Property X() As DoubleGetReturn mXEnd GetEnd PropertyPublic ReadOnly Property Y() As DoubleGetReturn mYEnd GetEnd PropertyPublic ReadOnly Property Z() As DoubleGetReturn mZEnd GetEnd PropertyPublic ReadOnly Property Luminocity() As DoubleGetReturn mLuminocityEnd GetEnd PropertyPublic ReadOnly Property ColorIndex() As DoubleGetReturn mColorIndexEnd GetEnd PropertyPublic Sub New(ByVal id As Int32,ByVal x As Double,ByVal y As Double,ByVal z As Double,ByVal spectr As String,ByVal luminocity As Double,ByVal colorIndex As Double)mHipID idmX xmY ymZ zmSpectr spectrmLuminocity luminocitymColorIndex colorIndexEnd SubEnd Class将数据文件添加到项目中。 将DevExpress Charts Demo随附的stardata.csv文件复制到项目目录新创建的Data目录中。注意默认情况下该文件位于C:甥敳獲PublicDocumentsDevExpress Demos 20.1ComponentsWPFCSChartsDemo.WpfData目录中。在解决方案资源管理器中切换Show All Files按钮然后右键单击Data目录。从调用的菜单中选择Include In Project。单击解决方案资源管理器中的stardata.csv文件然后在Properties窗口中将Build Action属性设置为Resource。ViewModel应该从数据文件加载模型对象像以前一样将文件添加到ViewModel的项目中。用以下代码替换新文件中的代码。C#using System;using System.Collections.Generic;using System.Collections.ObjectModel;using System.Globalization;using System.IO;using System.Windows;using System.Windows.Resources;namespace GettingStarted2 {public class StarStatisticsViewModel {public IEnumerable Stars { get; }public StarStatisticsViewModel() {Stars StarStatisticsLoader.Load(/Data/starsdata.csv);}}static class StarStatisticsLoader {public static IEnumerable Load(string filepath) {StreamResourceInfo streamInfo Application.GetResourceStream(new Uri(filepath, UriKind.RelativeOrAbsolute));StreamReader reader new StreamReader(streamInfo.Stream);Collection stars new Collection();while (!reader.EndOfStream) {String dataLine reader.ReadLine();String[] serializedValues dataLine.Split(;);stars.Add(new Star(id: Convert.ToInt32(serializedValues[0], CultureInfo.InvariantCulture),x: Convert.ToDouble(serializedValues[3], CultureInfo.InvariantCulture),y: Convert.ToDouble(serializedValues[4], CultureInfo.InvariantCulture),z: Convert.ToDouble(serializedValues[5], CultureInfo.InvariantCulture),spectr: serializedValues[1],luminocity: Convert.ToDouble(serializedValues[6], CultureInfo.InvariantCulture),colorIndex: Convert.ToDouble(serializedValues[2], CultureInfo.InvariantCulture)));}return stars;}}}VB.NETImports System.Collections.ObjectModelImports System.GlobalizationImports System.IOImports System.Windows.ResourcesPublic Class StarDataViewModelDim mStars As IEnumerable(Of Star)Public ReadOnly Property Stars As IEnumerable(Of Star)GetReturn mStarsEnd GetEnd PropertyPublic Sub New()mStars StarStatisticsLoader.Load(/Data/starsdata.csv)End SubEnd ClassPublic Module StarStatisticsLoaderPublic Function Load(ByVal filepath As String) As IEnumerable(Of Star)Dim streamInfo As StreamResourceInfo Application.GetResourceStream(New Uri(filepath, UriKind.RelativeOrAbsolute))Dim reader As StreamReader New StreamReader(streamInfo.Stream)Dim stars As Collection(Of Star) New Collection(Of Star)()While (Not reader.EndOfStream)Dim dataLine As String reader.ReadLine()Dim serializedValues As String() dataLine.Split(;)stars.Add(New Star(id:Convert.ToInt32(serializedValues(0), CultureInfo.InvariantCulture),x:Convert.ToDouble(serializedValues(3), CultureInfo.InvariantCulture),y:Convert.ToDouble(serializedValues(4), CultureInfo.InvariantCulture),z:Convert.ToDouble(serializedValues(5), CultureInfo.InvariantCulture),spectr:serializedValues(1),luminocity:Convert.ToDouble(serializedValues(6), CultureInfo.InvariantCulture),colorIndex:Convert.ToDouble(serializedValues(2), CultureInfo.InvariantCulture)))End WhileReturn starsEnd FunctionEnd Module现在将ViewModel分配给Window.DataContext属性选择Window找到DataContext属性然后单击New按钮。在调用的窗口中选择GettingStarted.StarDataViewModel类然后单击OK。准备工作完成这下一篇文章中将详细说明如何添加Chart3D控件分配数据和自定义显示设置。点击下方“了解更多”查看当下流行的界面开发组件
