问如何在C#中使用.csv文件以不同的名称逐个保存新文件

EN

- `List<DrawNew> dischargeMark1List` 
- `List<DrawNew> dischargeMark2List`
- `List<DrawNew> charge1Mark1List`
- `List<DrawNew>  charge1Mark2List`

    1. You create a method `GenerateOutputCsv(List<DrawNew> selectedData)` to write the data to the correct file name. You just have to do the same checking as you did in `btnSeperateFile_Click(..)` method. 

public class Charge
{
    public DateTime Date { get; set; } 
    public bool Pass { get; set; } 
    public bool CutMark { get; set; } 
    public int Marks { get; set; } 
}

var discharge1Mark1 = new List<Charge>();
var discharge1Mark2 = new List<Charge>();
var charge1Mark1 = new List<Charge>();
var charge1Mark2 = new List<Charge>();

var date = DateTime.ParseExact(valuesCsvLine[0], dateFormatString, CultureInfo.InvariantCulture);
            var pass = (valuesCsvLine[1] == "TRUE" ? true : false);
            var cutMark1 = (valuesCsvLine[2] == "TRUE" ? true : false);
            var marks1 = int.Parse(valuesCsvLine[3]);
            var cutMark2 = (valuesCsvLine[4] == "TRUE" ? true : false);
            var marks2 = int.Parse(valuesCsvLine[5]);
            if (pass)
            {
                if (cutMark1)
                    discharge1Mark1.Add(new Charge
                    {
                        Date = date,
                        Pass = pass,
                        Marks = marks1,
                        CutMark = cutMark1
                    });
                else
                    discharge1Mark2.Add(new Charge
                    {
                        Date = date,
                        Pass = pass,
                        Marks = marks2,
                        CutMark = cutMark2
                    });
            }else
            {
                if (cutMark1)
                    charge1Mark1.Add(new Charge
                    {
                        Date = date,
                        Pass = pass,
                        Marks = marks1,
                        CutMark = cutMark1
                    });
                else
                    charge1Mark2.Add(new Charge
                    {
                        Date = date,
                        Pass = pass,
                        Marks = marks2,
                        CutMark = cutMark2
                    });
            }

private void ExportToCSV(List<Charge> data, bool discharge, int num)

    var filename = discharge ? "Discharge1" : "Charge1";
    filename += (num == 1) ? "_Mark1.csv" : "_Mark2.csv";
    var headerCol1 = "Date";

    var headerCol3 = (num == 1) ? "CutMark1" : "CutMark2";

    //your exporting function below
