You can also just loop over your columns to get the information.

DataTable dt=...;
foreach (DataColumn c in dt.Columns)
{
  Console.WriteLine(c.ColumnName + " " + dt[c]);
}

You can just execute one query that will return the data in a datatable

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);

Now is dt filled with your information
