C＃Windows窗體圖表控件 - 綁定csv文件中的多個y值

Question

這是我第一次接觸數據綁定，所以我對所涉及的所有屬性和方法知之甚少。我想將多個系列綁定到csv文件，其中列1是DateTime，列2到N是雙打。我從WinFormsChartSamples中的示例開始，將單個Y值綁定到csv;但是，不要相信我理解綁定多個Y值的方式。

原始代碼：

string mySelectQuery = "Select * from " + file; 
string ConStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + 
path + ";Extended Properties=\"Text;HDR=No;FMT=Delimited\""; 

OleDbConnection myConnection = new OleDbConnection(ConStr); 

// create a database command on the connection using query 
OleDbCommand myCommand = new OleDbCommand(mySelectQuery, myConnection); 

// open the connection 
myCommand.Connection.Open(); 

// create a database reader 
OleDbDataReader myReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection); 

// column 1 is a time value, column 2 is a double 
// databind the reader to the chart using the DataBindXY method 
chart1.Series[0].Points.DataBindXY(myReader, "1", myReader, "2"); 

以下工作：

myCommand.Connection.Open(); 
OleDbDataReader myReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection); 
chart1.Series[0].Points.DataBindXY(myReader, "1", myReader, "2"); 

myCommand.Connection.Open(); 
myReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection); 
chart1.Series[1].Points.DataBindXY(myReader, "1", myReader, "3"); 

myCommand.Connection.Open(); 
myReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection); 
chart1.Series[2].Points.DataBindXY(myReader, "1", myReader, "4"); 

我可以把上面成一個循環，並遍歷所有系列的，但肯定有一個更好的辦法比通過多次讀取csv文件？

原來我沒有找到一個更好的辦法：

string mySelectQuery = "Select * from " + file; 
string ConStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + 
";Extended Properties=\"Text;HDR=No;FMT=Delimited\""; 

OleDbConnection myConnection = new OleDbConnection(ConStr); 
OleDbCommand myCommand = new OleDbCommand(mySelectQuery, myConnection); 

chart1.DataSource = myCommand; 

for (int i = 0; i < chart1.Series.Count; i++) { 
    chart1.Series[i].XValueMember = "1"; 
    chart1.Series[i].YValueMembers = (i+2).ToString(); 
} 
chart1.DataBind();
