How to Set data dynamic array From SQL in C#

Question

How to set data from SQL Server in C#.

My Class Student:

public class student
{
    public int StudentID { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

And I want to Set Data From SQL

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["conStr"].ConnectionString);
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "Select * From Student";
cmd.Connection = con;
DataTable datatable = new DataTable();
con.Open();
SqlDataAdapter sqlDataAdapter = new SqlDataAdapter(cmd);
sqlDataAdapter.Fill(datatable);
con.Close();
sqlDataAdapter.Dispose();
foreach (DataRow dr in datatable.Rows)
{
    //Set Data: ex: student[] students=new student[];
    //students=new students{StudentID=dr["ID"],FirstName=dr["FirstName"]}
    // ...
}

And My Code Set Data

namespace WebApi2.myapi
{
public class StudentController : ApiController
{
    student[] students = new student[]
     {
         new student { StudentID = 1, FirstName = "Jishan", LastName = "Siddique" },
         new student { StudentID = 2, FirstName = "Bharat", LastName = "Darji" },
         new student { StudentID = 3, FirstName = "Ravi", LastName = "Mori" },
         new student { StudentID = 4, FirstName = "Jay", LastName = "Singh" }
     };

    public IEnumerable<student> GetStudents()
    {
        return students;
    }
}
}

Finally: I would like 1 result like: student.StudentID = dr ["ID"]; student.FirstName = dr ["FirstName"]

Thank you all watch. Sorry for my bad english.

I'm searched result to google but not found

You can do it by getting value from the DataRow:

List<student> students = new List<student>();
foreach (DataRow dataRow in datatable.Rows)
{  

     students.Add(new student(){
         StudentID =dataRow["StudentID"];
         FirstName = dataRow["FirstName"] ;
         LastName = dataRow["LastName"] ;
     })
}

So, students collection will have all your students.
