问题描述
Hi
需要SeriesCollection的命名空间我的代码中找不到图表中的点数
我尝试了什么：
< pre>使用System;
使用 System.Collections.Generic;
使用 System.Linq;
使用 System.Web;
使用 System.Web.UI;
使用 System.Web.UI.WebControls;
使用 System.Drawing;
使用 System.Drawing.Drawing2D;
命名空间 dotnetpro
{
public partial class sample1：System.Web.UI.Page
{
protected void Page_Load（ object sender，EventArgs e）
{
Chart.TitleBox.Label.Text = 学生进度;
Chart.Width = 750 ;
Chart.Height = 550 ;
SeriesCollection mySC = Calculate（）;
Chart.XAxis.Label.Text = 标记;
Chart.YAxis.Label.Text = No of Students;
Chart.SeriesCollection.Add（Calculate（））;
Chart.DefaultSeries.DefaultElement.URL = JavaScript：myAlert（\'点击元素％名称in series％SeriesName \'）;
Chart.TitleBox.Position = TitleBoxPosition.Full;
Chart.TitleBox.Label.Font = new 字体（ TimesRoman， 10 ，FontStyle.Bold | FontStyle.Italic）;
Chart.TitleBox.Label.Alignment = StringAlignment.Center;
Chart.TitleBox.Label.Color = Color.DarkBlue;
Chart.TitleBox.Background.Color = Color.FromArgb（ 225 ， 122 ， 212 ）;
Chart.TitleBox.Padding = 7 ;
Chart.LegendBox.DefaultEntry.LabelStyle.Font = new 字体（ Arial， 10 ，FontStyle.Italic）;
Chart.LegendBox.Line.Color = Color.FromArgb（ 56 ， 66 ， 177 ）;
Chart.LegendBox.Line.Width = 2 ;
Chart.LegendBox.Background = new 背景（Color.FromArgb（ 165 ， 174 ， 255 ），Color.FromArgb（ 233 ， 235 ， 240 ）， 45 ）;
Chart.LegendBox.Orientation = dotnetCHARTING.Orientation.Bottom;
}
SeriesCollection Calculate（）
{
SeriesCollection SC = new SeriesCollection（）;
随机myR = 新随机（ 1 ）;
for （ int a = 0 ; < 4 ; a ++）
{
Series s = new Series（）;
s.Name = Series + a.ToString（）;
for （ int b = 0 ; b < 1 ; b ++）
{
元素e = new Element（）;
e.Name = 元素 + b.ToString（）;
e.YValue = myR.Next（ 50 ）;
s.Elements.Add（e）;
}
SC.Add（s）;
}
SC [ 0 ]。Element.Color = Color.FromArgb（ 49 ， 255 ， 49 ）;
SC [ 0 ]。元素[ 0 ]。Name = 英文;
SC [ 0 ]。LegendEntry.Value = 13;
SC [ 0 ] .LegendEntry.Name = 10-15之间;
SC [ 1 ]。Element.Color = Color.FromArgb（ 255 ， 255 ， 0 ）;
SC [ 1 ]。元素[ 0 ]。Name = 数学;
SC [ 1 ]。LegendEntry.Value = 32;
SC [ 1 ]。LegendEntry.Name = 10-40之间;
SC [ 2 ]。Element.Color = Color.FromArgb（ 255 ， 99 ， 49 ）;
SC [ 2 ]。元素[ 0 ]。Name = 科学;
SC [ 2 ]。LegendEntry.Value = 6;
SC [ 2 ]。LegendEntry.Name = 0-10之间;
SC [ 3 ]。Element.Color = Color.FromArgb（ 0 ， 156 ， 255 ）;
SC [ 3 ]。元素[ 0 ]。Name = 计算机;
SC [ 3 ]。LegendEntry.Value = 18;
SC [ 3 ]。LegendEntry.Name = 15-30之间;
return SC;
}
}
}
解决方案
听起来像你缺少命名空间引用。这里： SeriesCollection Class（System。 Windows.Forms.DataVisualization.Charting） [ ^ ]
解析命名空间的快速提示（和其他整洁的东西）：
在VS2015（和VS2013？）中，使用快捷键CTRL +将光标放在带有波浪形红线的行中的任何位置。 （CTRL键+'。'（点）键）或右键单击并选择快速操作和重构...，如果链接了正确的DLL，IntelliSense应该能够快速添加正确的使用{命名空间};参考
Hi
Need Namespaces for SeriesCollection And points in chart are not found in my code
What I have tried:
<pre>using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Drawing;
using System.Drawing.Drawing2D;
namespace dotnetpro
{
public partial class sample1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Chart.TitleBox.Label.Text = "Student Progress";
Chart.Width = 750;
Chart.Height = 550;
SeriesCollection mySC = Calculate();
Chart.XAxis.Label.Text = "Marks";
Chart.YAxis.Label.Text = "No of Students";
Chart.SeriesCollection.Add(Calculate());
Chart.DefaultSeries.DefaultElement.URL = "JavaScript: myAlert(\'Clicked on element %Name in series %SeriesName \')";
Chart.TitleBox.Position = TitleBoxPosition.Full;
Chart.TitleBox.Label.Font = new Font("TimesRoman", 10, FontStyle.Bold | FontStyle.Italic);
Chart.TitleBox.Label.Alignment = StringAlignment.Center;
Chart.TitleBox.Label.Color = Color.DarkBlue;
Chart.TitleBox.Background.Color = Color.FromArgb(225, 122, 212);
Chart.TitleBox.Padding = 7;
Chart.LegendBox.DefaultEntry.LabelStyle.Font = new Font("Arial", 10, FontStyle.Italic);
Chart.LegendBox.Line.Color = Color.FromArgb(56, 66, 177);
Chart.LegendBox.Line.Width = 2;
Chart.LegendBox.Background = new Background(Color.FromArgb(165, 174, 255), Color.FromArgb(233, 235, 240), 45);
Chart.LegendBox.Orientation = dotnetCHARTING.Orientation.Bottom;
}
SeriesCollection Calculate()
{
SeriesCollection SC = new SeriesCollection();
Random myR = new Random(1);
for (int a = 0; a < 4; a++)
{
Series s = new Series();
s.Name = "Series " + a.ToString();
for (int b = 0; b < 1; b++)
{
Element e = new Element();
e.Name = "Element " + b.ToString();
e.YValue = myR.Next(50);
s.Elements.Add(e);
}
SC.Add(s);
}
SC[0].Element.Color = Color.FromArgb(49, 255, 49);
SC[0].Elements[0].Name = "English";
SC[0].LegendEntry.Value = "13";
SC[0].LegendEntry.Name = "Between 10-15";
SC[1].Element.Color = Color.FromArgb(255, 255, 0);
SC[1].Elements[0].Name = "Maths";
SC[1].LegendEntry.Value = "32";
SC[1].LegendEntry.Name = "Between 10-40";
SC[2].Element.Color = Color.FromArgb(255, 99, 49);
SC[2].Elements[0].Name = "Science";
SC[2].LegendEntry.Value = "6";
SC[2].LegendEntry.Name = "Between 0-10";
SC[3].Element.Color = Color.FromArgb(0, 156, 255);
SC[3].Elements[0].Name = "Computer";
SC[3].LegendEntry.Value = "18";
SC[3].LegendEntry.Name = "Between 15-30";
return SC;
}
}
} 解决方案
Sounds like you are missing a namespace reference. Here: SeriesCollection Class (System.Windows.Forms.DataVisualization.Charting)[^]
A quick tip for resolving namespaces (and other neat stuff):
In VS2015 (and VS2013?), put the cursor anywhere in the line with the squiggly red line, using shortcut CTRL+. (CTRL key + '.' (Dot) key) or right-click and select "Quick Actions and Refactorings...", if the correct DLL is linked in, the IntelliSense should give you the ability to quickly add the correct Using {namespace}; reference.
