下面做了一个例子，如下图，这个例子的主要目的是，把业务模型实体类映射到具体的UI控件上

上面在Module(自己创建的业务工程)右键添加一个实体类模型 Attachment

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace SmartClient.Module
{
    public class Attachment
    {
        public event EventHandler StatusChanged;

        public enum AttachmentStatus
        {
            NotAvailable,
            Downloading,
            AvailableNotModified,
            AvailableModified,
            ToBeUploaded,
            Uploading,
            Uploaded
        }

        private string _displayName;

        public string DisplayName
        {
            get { return _displayName; }
            set { _displayName = value; }
        }

        private string _fileName;

        public string FileName
        {
            get { return _fileName; }
            set { _fileName = value; }
        }

        private string _documentUrl;

        public string DocumentUrl
        {
            get { return _documentUrl; }
            set { _documentUrl = value; }
        }

        private AttachmentStatus _status;

        public AttachmentStatus Status
        {
            get { return _status; }
            set
            {
                _status = value;
            }
        }

        private DateTime _localCreationTime;

        public DateTime LocalCreationTime
        {
            get { return _localCreationTime; }
            set { _localCreationTime = value; }
        }
    }
}

再添加一个映射器类,AttachmentMapper，它的作用是把这个业务实体绑定到ListView中

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace SmartClient.Module
{
    public static class AttachmentMapper
    {
        public static ListViewItem ToListViewItem(Attachment attachment)
        {
            return new AttachmentListViewItem(attachment);
        }

        public static Attachment FromListViewItem(ListViewItem listViewItem)
        {
            AttachmentListViewItem attachmentListViewItem =
                            listViewItem as AttachmentListViewItem;

            return attachmentListViewItem.Attachment;
        }

        private class AttachmentListViewItem : ListViewItem
        {
            private Attachment _attachment;

            public AttachmentListViewItem(Attachment attachment)
            {
                Name = attachment.DisplayName;
                Text = attachment.DisplayName;
                SubItems.Add(AttachmentStatusToDisplayText(attachment));
                _attachment = attachment;
            }

            private static string AttachmentStatusToDisplayText(Attachment attachment)
            {
                switch (attachment.Status)
                {
                    case Attachment.AttachmentStatus.AvailableModified:
                        return "Modified";

                    case Attachment.AttachmentStatus.AvailableNotModified:
                        return "Available";

                    case Attachment.AttachmentStatus.Downloading:
                        return "Downloading...";

                    case Attachment.AttachmentStatus.NotAvailable:
                        return "To be downloaded";

                    case Attachment.AttachmentStatus.ToBeUploaded:
                        return "To be uploaded";

                    case Attachment.AttachmentStatus.Uploaded:
                        return "Uploaded";

                    case Attachment.AttachmentStatus.Uploading:
                        return "Uploading";
                }

                return attachment.Status.ToString();
            }

            public Attachment Attachment
            {
                get { return _attachment; }
            }
        }
    }
}

然后我们在View中，拖放一个ListView上去，并命名为_attachmentsListView，并修改其.cs代码

using System;
using System.Windows.Forms;
using Microsoft.Practices.CompositeUI.SmartParts;
using Microsoft.Practices.ObjectBuilder;
using SmartClient.Infrastructure.Interface;

namespace SmartClient.Module
{
    public partial class View : UserControl, IView
    {
        public View()
        {
            InitializeComponent();
        }

        protected override void OnLoad(EventArgs e)
        {
            _presenter.OnViewReady();
            base.OnLoad(e);
            //加入如下代码，在窗体加载时执行对ListView的绑定
            var attachment = new Attachment();
            attachment.DisplayName = "这是一个测试";
            AddAttachmentToList(attachment);
        }

        private void AddAttachmentToList(Attachment attachment)
        {
            ListViewItem item = AttachmentMapper.ToListViewItem(attachment);
            _attachmentsListView.Items.Add(item);
        }
    }
}

最后我们得到如下的界面，ListView已经绑定上我们测试的数据
