List<ABC> lst = new List<ABC>()
{
    new ABC { ID = 1, birthdate = DateTime.Now, name = "Vijay", joinDate = DateTime.Now },
    new ABC { ID = 2, birthdate = DateTime.Now, name = "Sagar", joinDate = DateTime.Now },
    new ABC { ID = 3, birthdate = DateTime.Now, name = "Dhaval", joinDate = DateTime.Now },
};

List<string> availablefield = new List<string>();
availablefield.Add("ID");
availablefield.Add("birthdate");

Hi Kartik,

My final out is this type...

ID = 1, birthdate = DateTime.Now, name = "Vijay"
ID = 2, birthdate = DateTime.Now, name = "Sagar

if i am remove name in second list than name is remove.

using LINQ (Language-Integrated Query)[^] you can do it easier

C#

List<string> availablefield = new List<string>();
       availablefield.Add("Vijay");
       availablefield.Add("Sagar");

       lst = lst.Where(k => availablefield.Contains(k.name)).ToList();

C#

// using foreach loop
           List<ABC> lstOutput = new List<ABC>();
           foreach (ABC item in lst)
               if (availablefield.Contains(item.name))
                   lstOutput.Add(item);
