split list into two based on certain value

Hi,
This is one of the way:


string[] str = new string[] { "1", "2", "3" };
List> method1 = method(str, pdfdoc);
List> method(string[] str, List aa)
{
List> dd = new List>();
List dd1 = (from s in str
from ss in aa
where s == ss.FormID
select ss).ToList();
List dd2 = aa.Except(dd1).ToList();
dd.Add(dd1);
dd.Add(dd2);
return dd;
}

Hi Saket,

Use LINQ, it's quite beautiful while doing such manipulations.

Use the code below:
--------------------------------

List<Form> List1 = (from docs in pdfdoc where (docs.FormID.CompareTo("4") < 0) select docs).ToList();

List<Form> List2= (from docs in pdfdoc where (docs.FormID.CompareTo("4") > 0) select docs).ToList();

--------------------------------


Hope it helps!

Happy Coding :)

I have given you the solution in c# windows application. So add c# windows application and write following code in code behind of form.

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public string Name { get; set; }
        public string FormID { get; set; }
        public string Path { get; set; }
        List<Form1> pdfdoc;

        public Form1()
        {
            InitializeComponent();
        }

        public void Test()
        {
            pdfdoc = new List<Form1>{
                     new Form1{ Name="Form1", FormID ="1", Path="D:/Temp/"},
                     new Form1{ Name="Form2", FormID ="2", Path="D:/Temp/"},
                     new Form1{ Name="Form3", FormID ="3", Path="D:/Temp/"},
                     new Form1{ Name="Form4", FormID ="4", Path="D:/Temp/"},
                     new Form1{ Name="Form5", FormID ="5", Path="D:/Temp/"},
                     new Form1{ Name="Form6", FormID ="6", Path="D:/Temp/"},
                     new Form1{ Name="Form7", FormID ="7", Path="D:/Temp/"},
                     new Form1{ Name="Form8", FormID ="8", Path="D:/Temp/"},
                                    };
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            Test();
            List<Form1> pdfdoc1 = new List<Form1>();
            List<Form1> pdfdoc2 = new List<Form1>();
            for (int i = 0; i < pdfdoc.Count; i++)
            {
                if (Convert.ToInt32(pdfdoc[i].FormID) < 4)
                {
                    pdfdoc1.Add(pdfdoc[i]);
                }
                else if (Convert.ToInt32(pdfdoc[i].FormID) > 4)
                {
                    pdfdoc2.Add(pdfdoc[i]);
                }
            }
        }
    }
}
