在WinForms中实现工作单元

// 工作单元类
public class UnitOfWork
{
    private IDbConnection connection;
    private IDbTransaction transaction;

    public UnitOfWork()
    {
        connection = new SqlConnection("connectionString");
        connection.Open();
        transaction = connection.BeginTransaction();
    }

    public void Commit()
    {
        transaction.Commit();
        connection.Close();
    }

    public void Rollback()
    {
        transaction.Rollback();
        connection.Close();
    }
}

// 在WinForms中使用工作单元
public partial class MainForm : Form
{
    private UnitOfWork unitOfWork;

    public MainForm()
    {
        InitializeComponent();
        unitOfWork = new UnitOfWork();
    }

    private void btnSave_Click(object sender, EventArgs e)
    {
        try
        {
            // 执行数据库操作
            // ...

            unitOfWork.Commit();
            MessageBox.Show("保存成功");
        }
        catch (Exception ex)
        {
            unitOfWork.Rollback();
            MessageBox.Show("保存失败：" + ex.Message);
        }
    }
}
