如何使用LINQ将记录添加到数据库？

public class MyDataContext : DataContext
{
    public Table<Record> Records;

    public MyDataContext(string connectionString)
        : base(connectionString)
    {
    }
}

[Table(Name = "Records")]
public class Record
{
    [Column(IsPrimaryKey = true, IsDbGenerated = true)]
    public int Id { get; set; }

    [Column]
    public string Name { get; set; }

    [Column]
    public string Description { get; set; }
}

using (var context = new MyDataContext("connectionString"))
{
    var newRecord = new Record
    {
        Name = "New Record",
        Description = "This is a new record added using LINQ."
    };

    context.Records.InsertOnSubmit(newRecord);
    context.SubmitChanges();
}
