tfs - 如何获取 TFS 选项字段的选项列表？

Question

我正在研究 TFS API 2010。

我想获取一个字段的可用选项列表来创建一个 Combobox 控件。如：

优先级--> [1,2,3,4] 严重性-->['4-low','3-medium','2-height','1-Critical']

您需要从 TFS 导出 WorkItemType 定义，然后在 xml 中找到该字段并使用其中的值。下面是我用来获取转换列表的代码片段，如果您认为选项可能在全局列表中，那么您将在导出方法中设置标志为 true。

    public List<Transition> GetTransistions(WorkItemType workItemType)
    {
        List<Transition> currentTransistions;

        // See if this WorkItemType has already had it's transistions figured out.
        this._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 newTransitions = new List<Transition>();

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

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

        // Iterate all the transitions
        foreach (XmlNode transition in transitions)
        {
            // save off the transition 
            newTransitions.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.
        this._allTransistions.Add(workItemType, newTransitions);

        return newTransitions;
    }

过渡是我的一个小班，如下所示。

public class Transition
{
    #region Public Properties

    public string From { get; set; }

    public string To { get; set; }

    #endregion
}
