TFS API - 是否有办法获得工作项类型的转换列表？

Question

我想从状态“A”到状态“X”。

有在地方，防止我只是要X.

我可以导出WorkItemType XML和工作对转变，但在此之前我这样做，我想我会问，如果有一种方法通过API获取Transitions。

Answer 1

Soooo .....

没有多少人需要WorkItemTypes的转换。

那么，我需要它，所以我写了一个方法来做到这一点。在这种情况下，如果有其他人需要这个：

// Hold a list of all the transistions we have done. This will help us not have run them again If we already have. 
private static Dictionary<WorkItemType, List<Transition>> _allTransistions = new Dictionary<WorkItemType, List<Transition>>(); 

/// <summary> 
/// Get the transitions for this <see cref="WorkItemType"/> 
/// </summary> 
/// <param name="workItemType"></param> 
/// <returns></returns> 
private static List<Transition> GetTransistions(this WorkItemType workItemType) 
{ 
    List<Transition> currentTransistions; 

    // See if this WorkItemType has already had it's transistions figured out. 
    _allTransistions.TryGetValue(workItemType, out currentTransistions); 
    if (currentTransistions != null) 
     return currentTransistions; 

    // Get this worktype type as xml 
    XmlDocument workItemTypeXml = workItemType.Export(false); 

    // Create a dictionary to allow us to look up the "to" state using a "from" state. 
    var newTransistions = new List<Transition>(); 

    // get the transistions node. 
    XmlNodeList transitionsList = workItemTypeXml.GetElementsByTagName("TRANSITIONS"); 

    // As there is only one transistions item we can just get the first 
    XmlNode transitions = transitionsList[0]; 

    // Iterate all the transitions 
    foreach (XmlNode transition in transitions) 
    { 
     // save off the transistion 
     newTransistions.Add(new Transition 
           { 
            From = transition.Attributes["from"].Value, 
            To = transition.Attributes["to"].Value 
           }); 

    } 

    // Save off this transition so we don't do it again if it is needed. 
    _allTransistions.Add(workItemType, newTransistions); 

    return newTransistions; 
} 

public class Transition 
{ 
    public string To { get; set; } 
    public string From { get; set; } 
}
