行未添加到SQL（ODBC连接）

Question

Everything seems to be ok, I see rows when I want to read from SQL, but when I'm adding them they do not appear in SQL Server (Yes I did refresh the database). Here is my connection string:

connetionString = "Driver={Sql Server}; Server=baxu\\sqlexpress; Database = baza1;" + $"UID ={ username };PWD={ password };";

And here the code where I add rows:

cmdString = $"INSERT INTO {n} VALUES (?, ?);";
using (OdbcCommand comm = new OdbcCommand())
{
    comm.Connection = connection;
    comm.CommandText = cmdString;
    comm.Parameters.Add("value", System.Data.Odbc.OdbcType.Int).Value = value;
    comm.Parameters.Add("time", System.Data.Odbc.OdbcType.DateTime).Value = System.DateTime.Now;
    comm.ExecuteNonQuery();
    rows += 1;
}

@Ko Su, try this: I noticed that your definition of odbc connection variable and create command is the same.

using System;
using System.Data;
using System.Data.Odbc;

   class OdbcUpdate
   {
      static void Main()
      {

      OdbcConnection comm = new OdbcConnection("Driver={Sql Server}; Server=baxu\\sqlexpress; Database = baza1;" + $"UID ={ username };PWD={ password };"); 

      comm.Open();

      OdbcCommand myOdbcCommand = comm.CreateCommand();

      myOdbcCommand.CommandText = "INSERT INTO table1 (field1, field2) VALUES (?, ?)";

      myOdbcCommand.Parameters.Add("@field1", OdbcType.Int);
      myOdbcCommand.Parameters.Add("@field2", OdbcType.Int);

      myOdbcCommand.Parameters["@field1"].Value = 1;
      myOdbcCommand.Parameters["@field2"].Value = 2;

      Console.WriteLine("Number of Rows Affected is: {0}", myOdbcCommand.ExecuteNonQuery());

      comm.Close();

      Console.ReadKey();

      }
   }
