how to display 2 tables from mysql in visual studio 17 - mysql

Question

this is in my controller
string connStr = "server=" + IpAddress + ";user=" + UserName + ";database=" + DatabaseName + ";port=" + PortNumber + ";password=" + Password + ";SslMode=none;";
MySqlConnection conn = new MySqlConnection(connStr);
conn.Open();
string query = " select * from Cities,Regions";
MySqlCommand com = new MySqlCommand(query, conn);
MySqlDataAdapter da = new MySqlDataAdapter(com);
DataTable ds = new DataTable();
da.Fill(ds);
conn.Close();
I use a view model for displaying data from mysql and i fill them as below.
List<Models.ViewModels.city> CT = new List<Models.ViewModels.city>();
SftpClient sftpclient = new SftpClient("port", "root", "name");
sftpclient.Connect();
foreach (DataRow item in ds.Rows)
{
city ct = new city
{
CityName = item.itemArray[1].ToString(),
CityNumber = Convert.ToInt32(item.itemArray[2])
}
region rg = new region
{
RegionName = item.itemArray[1].ToString(),
RegionNumber = Convert.ToInt32(item.itemArray[2])
}
}
CT.Add(ct);
return View(CT.ToList());
How could i show regions in my razor. i already used viewbag for sending a list form my region viewmodel. but it doesn't fill the viewmodel obviously but how should i fill the region viewmodel
