I need to get data from a list but orderly mer mean get in the order, but I have this code is not working out.

if (item is TextBoxUniversal)
{
    foreach (string i in itemlist)
    {
        ItemValorEntity x = new ItemValorEntity();
        x.Item_Id = i[itemIndex].ToString();
        strItem = x.Item_Id;
        itemIndex += 1;
    }

    txt.Name = item.Name;
    txt = GetTexBox(txt.Name, groupBox1);
    itemValor.Item_Id = strItem;
    itemValor.cClave = Convert.ToString(cboGTTipoItems.SelectedValue);
    itemValor.Valor = txt.Text;
}

In a list I have several items can be 101, 102, 103, etc.. I need to get them in order. That code only managed to get 1 but is not is 1 is 101

if (item is TextBoxUniversal)
                {
                    string _item = itemlist[itemIndex].ToString();
                    itemIndex++;

                    txt.Name = item.Name;
                    txt = GetTexBox(txt.Name, groupBox1);
                    itemValor.Item_Id = _item;
                    itemValor.cClave = Convert.ToString(cboGTTipoItems.SelectedValue);
                    itemValor.Valor = txt.Text;
                }

I removed previous answer as I believe this is more what you're looking for. The ability to sort a list that you've received. Your question is still poorly asked, so I'm going to go off some assumptions you've implied. Those are:

• Utilize a hard-coded List.
• Sort the List.
• Display to a user.

The class you'll want to look at for the sort is List(T).Sort it provides a clean, quick, and simple approach to accomplish the goal. Details can be found here.

I'm going to use a more practical scenario, we have a series of students that will require their score / grades be sorted before output to our user.

To begin will build our Student object.

public class Student
{
     public string Name { get; set; }
     public int Score { get; set; }
     public string Grade { get; set; }
}

So far our object is pretty simple, it contains:

• Name (Who it is)
• Actual score (Numeric Representation)
• Grade (Letter Representation)

Now we will implement the IComparable<Student> to our Student object. This will implicitly implement the following method:

public int CompareTo(Student other)
{
    throw new NotImplementedException();
}

So we will remove the Exception out of the method and implement:

if(other == null)
     return 1;

else
     return this.Score.CompareTo(other.Score);

This small amount of code will do the following:

• If the object is null it will be greater.
• It will compare our current Property to our Parameter Value.

Now all we have to do for our implementation:

// Create Our List
List<Student> student = new List<Student>();

// Add our Students to the List
student.Add(new Student() { Name = "Greg", Score = 100, Grade = "A+" });
student.Add(new Student() { Name = "Kelli", Score = 32, Grade = "F" });
student.Add(new Student() { Name = "Jon", Score = 95, Grade = "A" });
student.Add(new Student() { Name = "Tina", Score = 93, Grade = "A-" });
student.Add(new Student() { Name = "Erik", Score = 82, Grade = "B" });
student.Add(new Student() { Name = "Ashley", Score = 75, Grade = "C" });

// Apply our Sort.
student.Sort();

// Loop through Our List:
foreach (Student placement in student)
     listBox1.Items.Add(placement.Name + " " + placement.Score + " " + placement.Grade);

That will put them in a Ascending order. You can tweak and configure to make it Descending should you require it, or even more complex. Hopefully this is a nice starting point.

Also some items have OrderBy or OrderByDescending accessible. So you can actually do code like this to a Dictionary.

student.OrderByDescending(s => s.Value);

You have a slew of possibilities, hopefully this gets you started and able to think about your implementation a bit.
