如何在C＃中使用TFS REST API在现有用户故事下创建子任务

Question

我知道，通过使用https://www.visualstudio.com/en-us/中提到的TFS REST API在批处理调用中创建用户故事和一个子任务的条款DOCS/INTEMENTATE/API/WIT/样本。

，但我的要求是我已经有一个现有的用户故事，我想在C＃中的现有用户故事下创建子任务。

有人知道如何做到这一点吗？

请参阅此示例代码：

var url= new Uri("https://XXX.visualstudio.com");
                VssCredentials c = new VssCredentials(new Microsoft.VisualStudio.Services.Common.VssBasicCredential(string.Empty, "[personal access token]"));
var connection = new VssConnection(url, c);
            var workitemClient = connection.GetClient<WorkItemTrackingHttpClient>();
            string projectName = "scrum2015";
            int parentWITId = 771;
            var patchDocument = new Microsoft.VisualStudio.Services.WebApi.Patch.Json.JsonPatchDocument();
            patchDocument.Add(new Microsoft.VisualStudio.Services.WebApi.Patch.Json.JsonPatchOperation() {
                Operation=Operation.Add,
                Path= "/fields/System.Title",
                Value="childWIT"
            });
            patchDocument.Add(new Microsoft.VisualStudio.Services.WebApi.Patch.Json.JsonPatchOperation()
            {
                Operation = Operation.Add,
                Path = "/relations/-",
                Value = new
                {
                    rel = "System.LinkTypes.Hierarchy-Reverse",
                    url = connection.Uri.AbsoluteUri+ projectName+ "/_apis/wit/workItems/"+parentWITId,
                    attributes = new
                    {
                        comment = "link parent WIT"
                    }
                }
            });
            var createResult = workitemClient.CreateWorkItemAsync(patchDocument, projectName, "task").Result;

您可以使用此示例(只需将错误更改为任务(：https：//www.visualstudio.com/en-us/docs/integrate/api/wit/wit/samples.create--错误

您还必须添加有关链接的信息：https：//www.visualstudio.com/en-us/docs/integrate/api/wit/work-items#with-a-a-work-work-item-link在您的情况下：

patchdocument [4] = new {op =" add"，path ="/restage/- "，value = new {rel =" system.linktypes.hierarchy-reverse"，url =" https：//accountName。visualstudio.com/_apis/wit/workitems/{userstory_id}}}};
