本文介绍了C# TFS API:显示带有文件夹和文件的项目结构，包括它们的 ChangeType(签出、删除、重命名)，就像在 Visual Studio 中一样的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
限时送ChatGPT账号..我需要创建 GUI 来显示我的 TFS 项目的所有可用文件夹和文件结构，对于特定文件夹.例如:我在屏幕截图上有DiagnosticsFolder":
I need to create GUI that shows all available folders and files structure for my TFS project, for particular folder. For example: I have "DiagnosticsFolder" like on screenshot:
并且我需要在所需文件夹下显示具有项目结构的Tree，包括这些文件和文件夹ChangeType(例如:编辑、由其他用户编辑、添加、删除等).
And I need to show Tree with project structure under required folder, including these files and folders ChangeType (for instance: edited, edited by another user, added, deleted etcetera).
我找到了很多部分解决方案，提供使用一些方法，但我还没有找到完整的解决方案，而且确定文件和文件夹状态(ChangeType)也相当具有挑战性.
I found a lot of partial solutions, offereing to use some methods, however I haven't found full solution, and it is fairly challenging to determine files and folders status (ChangeType ) too.

推荐答案
我自己已经完成了解决方案.它包括以下部分:1).查看代表源代码控制项的模型:
I've done solution myself. It includes following parts: 1). View Models that represents Source Control Item:
public abstract class SourceControlItemViewBaseModel : ViewModelBase
{
private string _name;
public string Name
{
get { return _name; }
set
{
_name = value;
OnPropertyChanged();
}
}
private string _localPath;
public string LocalPath
{
get { return _localPath; }
set
{
_localPath = value;
OnPropertyChanged();
}
}
private string _serverPath;
public string ServerPath
{
get { return _serverPath; }
set
{
_serverPath = value;
OnPropertyChanged();
}
}
private string _pendingSetName;
/// <summary>
/// Computer name where changes were made
/// </summary>
public string PendingSetName
{
get { return _pendingSetName; }
set
{
_pendingSetName = value;
OnPropertyChanged();
}
}
private string _pendingSetOwner;
/// <summary>
/// User Name who made the changes
/// </summary>
public string PendingSetOwner
{
get { return _pendingSetOwner; }
set
{
_pendingSetOwner = value;
OnPropertyChanged();
}
}
private string _toolTipText;
public string ToolTipText
{
get { return _toolTipText; }
set
{
_toolTipText = value;
OnPropertyChanged();
}
}
public string SourceServerItem
{
get { return _sourceServerItem; }
set
{
_sourceServerItem = value;
OnPropertyChanged();
}
}
private SourceControlState _state;
private string _sourceServerItem;
public SourceControlState State
{
get { return _state; }
set
{
_state = value;
OnPropertyChanged();
}
}
}
public class SourceControlFileViewModel : SourceControlItemViewBaseModel
{
}
public class SourceControlDirecoryViewModel : SourceControlItemViewBaseModel
{
public List<SourceControlItemViewBaseModel> Items { get; set; }
public SourceControlDirecoryViewModel()
{
Items = new List<SourceControlItemViewBaseModel>();
}
}
[Flags]//My own Enum that represents different states
public enum SourceControlState
{
Online = 0,
CheckedOut = 1,
Added = 2,
Deleted = 4,
Locked = 8,
Renamed = 16
}
2).使用递归方法构建结构树的存储库:
2). Repository with recursive method that build the structure tree:
/// <summary>

/// <param name="serverPath">TFS source path</param>
/// <param name="serverSourcePath">this path should be used in the case server item's name was changed. Needs to be used because TFS cannot get items from folder whose name has been changed</param>
/// <returns></returns>

我让它变得如此复杂，因为我必须使用不同的方法来提取文件的信息，而无需更改、更改以及其他用户所做的更改.允许异步使用的方法:公共任务> BuildSourceControlStructureAsync(string folderPath = ConstDefaultFlowsTfsPath){返回 Task.Run(() => BuildSourceControlStructure(folderPath));}
I've made it so complex because I had to use different method to extract information for files without changes, with changes and with changes that were made by another user. The method that allows async usage: public Task> BuildSourceControlStructureAsync(string folderPath = ConstDefaultFlowsTfsPath) { return Task.Run(() => BuildSourceControlStructure(folderPath)); }
3).源代码管理视图模型:
3). Source Control View model:
public class SourceControlViewModel : ViewModelBase
{
public IEnumerable<SourceControlItemViewBaseModel> SourceControlStructureItems { get; set; }
public async Task Init()
{
await SourceControlRepository.Instance.Init();
//Here the strucure builds
SourceControlStructureItems = await SourceControlRepository.Instance.BuildSourceControlStructureAsync();
}
}

在 XAML 中，您可以通过触发器和绑定找到不同的数据表示方法.
In XAML you can find different approaches of data presentation by triggers and bindings.
上面的代码有结果.它通过不同的图标、UI 更改和带有信息的工具提示来表示所有状态.
There is result of the code above. It represents all states by different icons, UI changes and tooltips with information.
