Intersect, Union, & Except.
i don't want get common elements or combine all elements oe except. I need only just checking exist or not. if exist return true otherwise false. When the both lists have same objects with same id in different order at the time I need true. For suppose if both lists different objects we will get false

Both two list objects have not sequence order and both lists are not created from same instance that's why Equals() and SequenceEqual() not supported. I want just checking all objects of one list exist in another list and another object have same object of first list.

My code worked properly but row can't be delete from database table.in datatable row deleted.after call the .da.update(ds,"student") need to effected database table but row can't be deleted in database table
my code:
SqlConnection con = new SqlConnection("Data Source=AMMA-PC\\SQLEXPRESS;Initial Catalog=E_learn;Integrated Security=True");
string query="select * from Student where sid="+TextBox1.Text;
SqlDataAdapter da = new SqlDataAdapter(query, con);
SqlCommandBuilder br = new SqlCommandBuilder(da);
DataSet ds = new DataSet();
da.Fill(ds, "Student");
if (ds.Tables[0].Rows.Count > 0)
{
DataTable dt = ds.Tables[0];
DataColumn[] keyColumns = new DataColumn[1];
keyColumns[0] = dt.Columns["sid"];
dt.PrimaryKey = keyColumns;
DataRow dr = dt.Rows[0];
dt.Rows.Remove(dr);
da.Update(ds, "Student");
Response.Write("deleted successfully");
}
I think u have doubt about delete row. how should know row deleted from datatable in dataset. i had verfied through breaking points keys like F10,F11.at the time in dataset visualizer shows before call da.update(ds,"Student") i have row. after call da.update(ds,"Student").dataset visualizer shows row deleted but database does not effected.row can't be deleted from database . what is the problem
