c# - 如何以编程方式链接 Azure DevOps 中的分支和工作项

Question

我正在尝试找到一种方法，通过我正在构建的应用程序将分支添加为 Azure DevOps 中的链接 ( Basically just this, but within a C# console app )。

我越来越熟悉 VisualStudio Services 和 TeamFoundation .NET 库，并尝试通过 DevOps UI 创建的其中一个链接来获取工作项，并将其移植到另一个工作项，作为示例像这样:

var workItemWithBranchLink = await _WorkItemTrackingHttpClient.GetWorkItemAsync(3985, expand: WorkItemExpand.Relations);
var workItemWithoutBranchLink = await _WorkItemTrackingHttpClient.GetWorkItemAsync(3988, expand: WorkItemExpand.Relations);
var document = new JsonPatchDocument();
document.Add(new JsonPatchOperation()
{
    Operation = Operation.Add,
    Path = "/relations",
    Value = workItemWithBranchLink.Relations 
});
await _WorkItemTrackingHttpClient.UpdateWorkItemAsync(document, (int)workItemWithoutBranchLink.Id);

但是，这会引发异常

Microsoft.VisualStudio.Services.WebApi.Patch.PatchOperationFailedException: 'Work item patch does not support patching the top level property at path /relations.

由于 workItemWithoutBranchLink.Relations 为空，我不确定我还能如何修补它。

有什么想法吗？

对于 git 链接，语法略有不同，这是一个工作示例(链接 master 分支):

VssConnection testConnection = new VssConnection(new Uri("azure-devops-uri"), new Microsoft.VisualStudio.Services.Common.VssCredentials());
var workItemClient = testConnection.GetClient<WorkItemTrackingHttpClient>();
var gitClient = testConnection.GetClient<GitHttpClient>();
string projectId = "cf456145-abgd-ffs23-be61-0fca39681234";
string repositoryId = "d6856145-abgd-42a3-be61-0fca3968c555";
var branchUri = string.Format
(
    "vstfs:///Git/Ref/{0}%2f{1}%2f{2}",
    projectId,
    repositoryId,
    "GBmaster"
);

var json = new JsonPatchDocument();
json.Add(
new JsonPatchOperation()
{
     Operation = Operation.Add,
     Path = "/relations/-",
     Value = new
     {
            rel = "ArtifactLink",
            url = branchUri,
            attributes = new
            {
                name = "Branch",
                comment = "Comment"
            }
     }
});

try
{
     int workItemToUpdate = 142144;
     var update = workItemClient.UpdateWorkItemAsync(json, workItemToUpdate).Result;
}
catch (Exception e)
{
     var error = e.Message;
}
