基于 T4 + DevExpress 的 WinForm 自动化开发脚手架

// Users.cs - 自动生成
public partial class Users
{
    public int UserID { get; set; }
    public string UserName { get; set; }
    public string Password { get; set; }
    public string Email { get; set; }
    public DateTime CreateTime { get; set; }
}

// UsersAdoDAL.cs - 自动生成
public class UsersAdoDAL
{
    public int Add(Users model)
    {
        string sql = "INSERT INTO Users (UserName, Password, Email) VALUES (@UserName, @Password, @Email)";
        return SqlHelper.ExecuteNonQuery(sql, model);
    }

    public int Update(Users model)
    {
        string sql = "UPDATE Users SET UserName=@UserName, Password=@Password, Email=@Email WHERE UserID=@UserID";
        return SqlHelper.ExecuteNonQuery(sql, model);
    }

    public int Delete(int userId)
    {
        string sql = "DELETE FROM Users WHERE UserID=@UserID";
        return SqlHelper.ExecuteNonQuery(sql, new { UserID = userId });
    }

    public List<Users> GetList(string where, params SqlParameter[] parameters)
    {
        // 分页查询实现
        return AdoPagingHelper.GetPageList<Users>(where, parameters);
    }
}

// UsersAdoBLL.cs - 自动生成
public class UsersAdoBLL
{
    private UsersAdoDAL dal = new UsersAdoDAL();

    public bool Add(Users model)
    {
        // 业务逻辑校验
        if (string.IsNullOrEmpty(model.UserName))
            throw new Exception("用户名不能为空");

        return dal.Add(model) > 0;
    }

    public bool Update(Users model)
    {
        return dal.Update(model) > 0;
    }

    public bool Delete(int userId)
    {
        return dal.Delete(userId) > 0;
    }

    public List<Users> GetList(string where, params SqlParameter[] parameters)
    {
        return dal.GetList(where, parameters);
    }
}

// 自动生成的列表界面
public partial class Users_List_XtraUserControl : XtraUserControl
{
    private UsersAdoBLL bll = new UsersAdoBLL();

    public Users_List_XtraUserControl()
    {
        InitializeComponent();
        InitGrid();  // 自动初始化 GridControl 列
        LoadData();
    }

    private void LoadData()
    {
        gridControl1.DataSource = bll.GetList("");
    }

    // 增删改查按钮事件自动生成
}

// 自动生成的编辑界面
public partial class Users_Edit_XtraUserControl : XtraUserControl
{
    private UsersAdoBLL bll = new UsersAdoBLL();

    public Users_Edit_XtraUserControl()
    {
        InitializeComponent();
        // 自动创建 LayoutControl 和编辑控件
    }

    private void btnSave_Click(object sender, EventArgs e)
    {
        var user = new Users
        {
            UserName = txtUserName.Text,
            Password = txtPassword.Text,
            Email = txtEmail.Text
        };

        bll.Add(user);
    }

    // 数据绑定、验证自动生成
}
