將ListArray數據類型綁定到燭臺圖表系列

Question

將ListArray綁定到C＃（VS2015）中的燭臺圖表時遇到問題。我一直在我的桌子上敲着我的頭一天...現在有時間問。 :)在我看來，圖表類真的想綁定到數據庫。我希望能夠生成少量的股票數據，然後將其推入燭形圖表。 我的代碼：

public class Record 
{ 
    int id; 
    string time_stamp; 
    double open, close, high, low; 
    public Record(int id, string time_stamp, double open, double close, double high, double low) 
    { 
     this.id = id; 
     this.open = open; 
     this.close = close; 
     this.high = high; 
     this.low = low; 
    } 
    public int ID 
    { 
     get { return id; } 
     set { id = value; } 
    } 
    public string TimeStamp 
    { 
     get { return time_stamp; } 
     set { time_stamp = value; } 
    } 
    public double Open 
    { 
     get { return open; } 
     set { open = value; } 
    } 
    public double Close 
    { 
     get { return close; } 
     set { close = value; } 
    } 
    public double High 
    { 
     get { return high; } 
     set { high = value; } 
    } 
    public double Low 
    { 
     get { return low; } 
     set { low = value; } 
    } 

} 

public partial class Form1 : Form 
{ 
    public Form1() 
    { 
     InitializeComponent(); 

     ArrayList listDataSource = new ArrayList(); 

     //add some members to list 
     listDataSource.Add(new Record(1, "4 oclock", 10, 5, 7, 8)); 
     listDataSource.Add(new Record(1, "5 oclock", 11, 4, 4, 9)); 

     chart1.Series["Series1"].XValueMember = "Time"; 
     chart1.Series["Series1"].YValueMembers = "High, Low, Open, Close"; 
     chart1.Series["Series1"].CustomProperties = "PrieceDownColor=Red,PriceUpColor=green"; 
     chart1.Series["Series1"]["ShowOpenClose"] = "Both"; 
     chart1.DataManipulator.IsStartFromFirst = true; 
     chart1.DataSource = listDataSource; 
     chart1.DataBind(); // fails to bind 
    } 
} 

幫助！

看起來問題在於你所引用的Time哪些不存在，你應該參考TimeStamp。您還需要在構造函數中設置值TimeStamp。

更新：這是它看起來像下面的工作代碼：

public partial class Form1 : Form 
{ 
    public Form1() 
    { 
     InitializeComponent(); 

     ArrayList listDataSource = new ArrayList(); 

     //add some members to list 
     listDataSource.Add(new Record(1, "4 oclock", 10, 5, 7, 8)); 
     listDataSource.Add(new Record(1, "5 oclock", 11, 4, 4, 9)); 



     chart1.Series["Series1"].XValueMember = "TimeStamp"; 
     chart1.Series["Series1"].YValueMembers = "High, Low, Open, Close"; 
     chart1.Series["Series1"].CustomProperties = "PrieceDownColor=Red,PriceUpColor=green"; 
     chart1.Series["Series1"]["ShowOpenClose"] = "Both"; 
     chart1.DataManipulator.IsStartFromFirst = true; 

     chart1.DataSource = listDataSource; 

     chart1.DataBind(); 

    } 

} 

public class Record 
{ 
    int id; 
    string time_stamp; 
    double open, close, high, low; 
    public Record(int id, string time_stamp, double open, double close, double high, double low) 
    { 
     this.id = id; 
     this.time_stamp = time_stamp; 
     this.open = open; 
     this.close = close; 
     this.high = high; 
     this.low = low; 
    } 
    public int ID 
    { 
     get { return id; } 
     set { id = value; } 
    } 
    public string TimeStamp 
    { 
     get { return time_stamp; } 
     set { time_stamp = value; } 
    } 
    public double Open 
    { 
     get { return open; } 
     set { open = value; } 
    } 
    public double Close 
    { 
     get { return close; } 
     set { close = value; } 
    } 
    public double High 
    { 
     get { return high; } 
     set { high = value; } 
    } 
    public double Low 
    { 
     get { return low; } 
     set { low = value; } 
    } 

}
