是否可以将多维数组存储到对象中？

Question

Here are my classes:

public class Type_WorkSched
{
    public string EmployeeID { get; set; }
    public string RecordID { get; set; }
    public Type_Schedule[] Schedule { get; set; }
}

public class Type_Schedule
{
    public string Days { get; set; }
    public string TimeIn_AM { get; set; }
    public string TimeOut_AM { get; set; }
    public string TimeIn_PM { get; set; }
    public string TimeOut_PM { get; set; }
}

I want to store an array of MySchedule into an object MyWorkSched .

But I get only the last value of the array.

GV_WorkSched is the name of the datagrid.

Type_Schedule[] MySchedule = new Type_Schedule[GV_WorkSched.RowCount-1];
Type_WorkSched MyWorkSched = new Type_WorkSched();
           
MyWorkSched.EmployeeID = Txt_EmployeeID.Text;
MyWorkSched.RecordID = Txt_RecordNumber.Text;

for (int i = 0; i < GV_WorkSched.RowCount-1; i++)
{
    MySchedule[i] = new Type_Schedule();
    MySchedule[i].Days = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(i, "Days"));
    MySchedule[i].TimeIn_AM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(i, "TimeIn_AM"));
    MySchedule[i].TimeOut_AM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(i, "TimeOut_AM"));
    MySchedule[i].TimeIn_PM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(i, "TimeIn_PM"));
    MySchedule[i].TimeOut_PM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(i, "TimeOut_PM"));
                
    MyWorkSched.Schedule = new Type_Schedule[] { MySchedule[i] };
}

Or is there another way to do it?

Answer 1

You should do it as below

        Type_Schedule[] MySchedule = new Type_Schedule[GV_WorkSched.RowCount];
        Type_WorkSched MyWorkSched = new Type_WorkSched();
       
        MyWorkSched.EmployeeID = Txt_EmployeeID.Text;
        MyWorkSched.RecordID = Txt_RecordNumber.Text;

        for (int i = 0; i < GV_WorkSched.RowCount; i++)
        {
            MySchedule[i] = new Type_Schedule();
            MySchedule[i].Days = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(i, "Days"));
            MySchedule[i].TimeIn_AM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(i, "TimeIn_AM"));
            MySchedule[i].TimeOut_AM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(i, "TimeOut_AM"));
            MySchedule[i].TimeIn_PM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(i, "TimeIn_PM"));
            MySchedule[i].TimeOut_PM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(i, "TimeOut_PM"));
        }

        MyWorkSched.Schedule = MySchedule;

Your problem is on this line

MyWorkSched.Schedule = new Type_Schedule[] { MySchedule[i] }

At the end of each iteration, you create a new array, with only one value in it (the latest). When you get out of it this is the only one that remains.

Try the following. I totally removed the intermediate array as I think it was part of the confusion.

    Type_WorkSched MyWorkSched = new Type_WorkSched();
    MyWorkSched.Schedule = new Type_Schedule[GV_WorkSched.RowCount];
           
    MyWorkSched.EmployeeID = Txt_EmployeeID.Text;
    MyWorkSched.RecordID = Txt_RecordNumber.Text;
    for (int i = 0; i < GV_WorkSched.RowCount-1; i++)
    {
         MyWorkSched.Schedule[i] = new Type_Schedule();
         MyWorkSched.Schedule[i].Days = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(i, "Days"));
         MyWorkSched.Schedule[i].TimeIn_AM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(i, "TimeIn_AM"));
         MyWorkSched.Schedule[i].TimeOut_AM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(i, "TimeOut_AM"));
         MyWorkSched.Schedule[i].TimeIn_PM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(i, "TimeIn_PM"));
         MyWorkSched.Schedule[i].TimeOut_PM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(i, "TimeOut_PM"));
  }

        Type_Schedule[] MySchedule = new Type_Schedule[GV_WorkSched.RowCount-1];
                    Type_WorkSched MyWorkSched = new Type_WorkSched();
                   
                        MyWorkSched.EmployeeID = Txt_EmployeeID.Text;
                        MyWorkSched.RecordID = Txt_RecordNumber.Text;
                   
    MyWorkSched.Schedule = new Type_Schedule[] { 
    new Type_Schedule {
                    Days = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(GV_WorkSched.RowCount-1, "Days")),
                    TimeIn_AM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(GV_WorkSched.RowCount-1, "TimeIn_AM")),
                    TimeOut_AM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(GV_WorkSched.RowCount-1, "TimeOut_AM")),
                    TimeIn_PM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(GV_WorkSched.RowCount-1, "TimeIn_PM")),
                    TimeOut_PM = Convert.ToString(GV_WorkSched.GetRowCellDisplayText(GV_WorkSched.RowCount-1, "TimeOut_PM"))
                 };
     };
Since you are any ways trying to fetch the last value only why do you want to reassign a new Type_Schedule array every time in the loop.Avoid the loop  and if  you want to store the entire schedule data then use a loop.
MyWorkSched.Schedule = new Type_Schedule[] { MySchedule[i] };// this line if inside the loop at the end of the loop will give the same result as above

I suggest to use List<> instead. First, redeclare your type as

public class Type_WorkSched
{
    public string EmployeeID { get; set; }
    public string RecordID { get; set; }
    public List<Type_Schedule> Schedule { get; set; }

    // In case you really need it as Array
    public Type_Schedule[] ScheduleAsArray()
    {
        return Schedule.ToArray();
    }
}

Second, iterate your grid in foreach way

foreach (DataGridViewRow row in GV_WorkSched.Rows)
{

    var schedule = new Type_Schedule
    {
        Days = row.Cells["Days"].Value.toString(),
        //...
    };

    MyWorkSched.Schedule.Add(schedule);
}
