在c#中向工厂模式体系结构传递参数

我想实现工厂模式架构。我已经创建了带有参数化函数的接口。

1)步骤1:

public  interface IDatabase
    {
        bool Create(string userId,string password,string host,string dbName);
        bool Delete(string userId, string password, string host, string dbName);
    }

步骤2:

这个接口在下面的类中实现:-

public class IntialDBSetup : IDatabase
    {    
        public bool Create(string userId, string password, string host, string dbName)
        {
            SqlConnection con = new SqlConnection("Data Source=" + host + ";uid=" + userId + ";pwd=" + password + "");
            try
            {    
                string strCreatecmd = "create database " + dbName + "";
                SqlCommand cmd = new SqlCommand(strCreatecmd, con);
                con.Open();
                cmd.ExecuteNonQuery();
                con.Close();
                var file = new System.IO.FileInfo(System.Web.HttpContext.Current.Server.MapPath(ConfigurationManager.AppSettings["ScriptLocation"]));
                string strscript = file.OpenText().ReadToEnd();
                string strupdatescript = strscript.Replace("[OWpress]", dbName);
                var server = new Microsoft.SqlServer.Management.Smo.Server(new Microsoft.SqlServer.Management.Common.ServerConnection(con));
                server.ConnectionContext.ExecuteNonQuery(strupdatescript);
                con.Close();
                return true;    
            }
            catch (Exception ex)
            {
                return false;    
            }               
        }    
        public bool Delete(string userId, string password, string host, string dbName)
        {
            throw new NotImplementedException();
        }
    }

步骤3:

创建工厂类

public class DBFactory
{
   public static IDatabase DbSetup(string DbType, string userId, string password, string host, string dbName)
   {
       try
       {
           if (DbType == DBTypeEnum.IntialDB.ToString())
           {               
               return new IntialDBSetup();
           }             
       }
       catch (Exception ex)
       {
           throw new ArgumentException("DB Type Does not exist in our Record");             
       }
       return null;           
   }
}

这里我想传递一些参数给我的类，我怎样才能得到这个呢?
