We can get Schema it dataTable using SQLdataReader like private DataTable getTablesSchema() { string connectionString = Data Source=sandeepss- PC;database=Development;user=sa;password=knowdev ; SqlConnection con = new SqlConnection (); con.ConnectionString = connectionString; SqlCommand cmd = new SqlCommand ( Select * from Information_Schema.Tables  con); con.Open(); SqlDataReader dr = cmd.ExecuteReader(); DataTable dt = new DataTable (); dt.Load(dr); return dt; } if we define condtion for table in select query then we get table specific schema. Here we are showing Schema for TABLE and View you defien your WHERE clause in SELECT statment according to TABLE_NAME = EMPLOYEE and TABLE_TYPE=BASE TABLE

yes we can..But it will take some extra coding instead.. So you can sue DataAdapter.. SqlConnection cn = new SqlConnection(PutYourConnectionStringOverHere); SqlDataAdapter da = new SqlDataAdapter(SELECT * FROM Information_Schema.Tables where Table_Type = 'BASE TABLE' cn); DataTable dt = new DataTable(); da.Fill(dt); accept this answer if it solves your issue..
