Question

Hi all I am having a requirement like selecting multiple values and then to delete. I will have some list of EMployee IDs along with Dates and PayID values.

I will get all this fields in multiple. Now i would like to add this to dictionary element like for particular EmpID I have to assign Date and PayID as keys.

I thought of writing like this

public struct MyValue
{
    public List<int> lst;
    public List<int> lst1;
    public List<DateTime> lstdt;
}

public class MyDictionary : Dictionary<int, MyValue>
{
    public void Add(int key, List<int> lst1, List<int> lst2, List<DateTime> lstDt1)
    {
        MyValue v1=new MyValue();
        v1.lst = lst1;
        v1.lst1 = lst2;
        v1.lstdt = lstDt1;
        this.Add(key, v1);
    }
}

But I am little bit confused in dealing with this so can any one give me an idea to implement as per my requirement.

This is my requirement if I have EmpID as 1 for this I will have Multiple PayIDs and Dates like 1 and System Date.

Even I will get Mutilple EmpIDs But if exists already in the dictionary as Key element I don’t want to add it again.

(using 2.0 framework)

How can I do this?

Here is what i am doing i will have a grid with check boxes to delete the records. This gridview holds EmpID PayID and Date

Now if a user select some multiple check boxes and tries to delete i would like to store the values to a Dictionary. I will get multiple EmpID from the selection in which the same EmpID may exists for multiple times. So what i need to do is i would like to store the corresponding Values to a Dictionary with EmpID as Key value and the Values to the dictionary as multiple which will be the PayID and Date.

Sample structure of my Gridview

       Chkbox     EmpID    PayID     Date
        chk        123       1     8-31-2011
        chk        123       2     10-31-2011
        chk        1234       1     18-31-2011
        chk        1234       1     19-31-2011

for EmpID 123 i would like to assign 1,2 and the 2 dates as Values

Answer 1

Can any one tell what’s wrong in this

   arrEmpID.Add(1);
    arrEmpID.Add(1);
    arrEmpID.Add(2);
    arrEmpID.Add(2);

    arrPay.Add(1);
    arrPay.Add(1);
    arrPay.Add(2);
    arrPay.Add(2);


    DateTime dt = DateTime.Now;
    DateTime dt1 = DateTime.Now.AddMinutes(1);
    DateTime dt2 = DateTime.Now.AddMinutes(1);
    DateTime dt3 = DateTime.Now.AddMinutes(1);

    arrPayID.Add(dt);
    arrPayID.Add(dt1);
    arrPayID.Add(dt2);
    arrPayID.Add(dt3);

    EmpIDs = (int[])arrEmpID.ToArray(typeof(int));
    Dates = (DateTime[])arrPayID.ToArray(typeof(DateTime));
    PayIDs = (int[])arrPay.ToArray(typeof(int));

for (int i = 0; i < EmpIDs.Length; i++)
    {
        if (!(d.ContainsKey(EmpIDs[i])))
        {
            List<int> values = new List<int>();
            List<DateTime> ldt = new List<DateTime>();
            d.Add(EmpIDs[i], values, ldt);
        }
        d[EmpIDs[i]].lst.Add(PayIDs[i]);
        d[EmpIDs[i]].lstdt.Add(Dates[i]);
    }

   foreach (int EmpID in d.Keys)
    {
        foreach (int pID in d[EmpID].lst) // I just missed out this values
        {
            sb.Append(pID);
            sb.AppendLine(" ");
        }
        foreach (DateTime dtTimes in d[EmpID].lstdt)  // I just missed out this values
        {

            sb1.Append(dtTimes.ToString("MMddyyyy"));
            sb1.AppendLine(" ");
        }
    }

    Label1.Text = sb.ToString();
    Label2.Text = sb1.ToString();

I have my dictionary as follows

public struct MyValue
{
    public List<int> lst;
    public List<DateTime> lstdt;
}

public class MyDictionary : Dictionary<int, MyValue>
{
    public void Add(int key, List<int> lst1, List<DateTime> lstDt1)
    {
        MyValue v1 = new MyValue();
        v1.lst = lst1;
        v1.lstdt = lstDt1;
        this.Add(key, v1);
    }
}
