c#sql插入了很多参数

using (SqlConnection connection = new SqlConnection(connectionString))
{
    connection.Open();
    using (SqlCommand command = new SqlCommand(query, connection))
    {
        command.Parameters.AddWithValue("@param1", param1);
        command.Parameters.AddWithValue("@param2", param2);
        // ...
        command.ExecuteNonQuery();
    }
}

using (SqlConnection connection = new SqlConnection(connectionString))
{
    connection.Open();
    using (SqlCommand command = new SqlCommand(query, connection))
    {
        SqlParameter param1 = new SqlParameter("@param1", SqlDbType.Int);
        param1.Value = param1;
        command.Parameters.Add(param1);

        SqlParameter param2 = new SqlParameter("@param2", SqlDbType.NVarChar);
        param2.Value = param2;
        command.Parameters.Add(param2);

        // ...
        command.ExecuteNonQuery();
    }
}
