c＃postgresql多个添加值

Question

我正在玩PostgreSQL和c＃。我正在输入多个.AddWithValues（）来填充所有数据。考虑到真正的数据库将有更多的密钥，这可能会变得毛茸茸。 有没有办法将多个AddWithValues（）组合成一行或操作？

这是我的代码：

//Open the connection

//Made the id as a Guid. For now just using var id = new Guid()

//Insert multiple rows
using(var command = new NpgsqlCommand())
{
     command.Connection = connection;
     command.CommandText = "INSERT INTO testschema.testtable" +
                        "(name, id, number)" +
                        "VALUES (@name, @id, @number)";
     command.Parameters.AddWithValue("name", "Greg");
     command.Parameters.AddWithValue("id", id);
     command.Parameters.AddWithValue("number", 7);
     command.ExecuteNonQuery(); //Needs to be inside the loop

     //TODO: have the command text and parameters constructed once(Using the Parameters.Add for the parameters
     // and change values in the loop.

     //Also should have one connection open. So open just before the loop and close it after
 }

 //Close the connection
