如何以编程方式将Azure DevOps Pull请求设置为自动完成？

Question

当我在下面的代码中显示创建拉取请求时，我也想将其设置为自动完成。表示当满足其上的所有完成条件时，拉取请求自动完成，因此作者不必通过vsts界面手动完成它。

有关如何执行此操作的任何建议吗？在拉动请求创建时，我似乎没有任何可能性。换句话说，用于创建拉取请求的界面不显示任何自动完成选项。

这是我的示例代码：

public static void CreatePullRequestAndSetAutoComplete(GitHttpClient gitHttpClient, string repositoryId, GitPullRequest pullRequest, string mergeCommitMessage)
        {
            pullRequest = gitHttpClient.CreatePullRequestAsync(
                pullRequest, 
                repositoryId, 
                cancellationToken: CancellationToken.None).Result;
}

这是一个两步的过程。首先，您需要创建一个拉取请求，然后通过设置其自动完成程序的标识以及可选的一些其他参数来更新它，如下面的代码所示。

using System.Threading;
using Microsoft.TeamFoundation.SourceControl.WebApi;
using Microsoft.VisualStudio.Services.WebApi;

namespace CreateVstsPullRequestAndSetAutoComplete
{
    public class PullRequestAutoCompleter
    {
        /// <summary>
        /// Creates a pull request, and then sets it to auto complete. 
        /// </summary>
        /// <param name="gitHttpClient">GitHttpClient that is created for accessing vsts repo, and codebase.</param>
        /// <param name="repositoryId">The unique identifier of the repository</param>
        /// <param name="pullRequest">The pull request to be created, and then set autocomplete.</param>
        /// <param name="mergeCommitMessage">Provides text to post, when the pull request is completed and merged.</param>
        public static GitPullRequest CreatePullRequestAndSetAutoComplete(GitHttpClient gitHttpClient, string repositoryId, GitPullRequest pullRequest, string mergeCommitMessage)
        {
            // 1- Create the pull request.
            pullRequest = gitHttpClient.CreatePullRequestAsync(
                pullRequest, 
                repositoryId, 
                cancellationToken: CancellationToken.None).Result;

            //2- Set autocomplete.
            pullRequest = EnableAutoCompleteOnAnExistingPullRequest(gitHttpClient, pullRequest, mergeCommitMessage);

            return pullRequest;
        }

        /// <summary>
        /// Sets an existing (meaning created earlier) pullrequest to complete automatically, 
        /// once all of its completion conditions are resolved.
        /// (i.e., a(many) reviewer(s) has(have) approved the pull request, the author has resolved all the commits, and etc)
        /// </summary>
        /// <param name="gitHttpClient">GitHttpClient that is created for accessing vsts repo, and codebase.</param>
        /// <param name="pullRequest">Is an existing pull request, meaning it was created before.</param>
        /// <param name="mergeCommitMessage">Provides text to post, when the pull request is completed and merged.</param>
        /// <returns>An updated pull request, where the update is maninly about setting the autocomplete on it. </returns>
        public static GitPullRequest EnableAutoCompleteOnAnExistingPullRequest(GitHttpClient gitHttpClient, GitPullRequest pullRequest, string mergeCommitMessage)
        {
            var pullRequestWithAutoCompleteEnabled = new GitPullRequest
            {
                AutoCompleteSetBy = new IdentityRef { Id = pullRequest.CreatedBy.Id },
                CompletionOptions = new GitPullRequestCompletionOptions
                {
                    SquashMerge = true,
                    DeleteSourceBranch = true, // false if prefered otherwise
                    MergeCommitMessage = mergeCommitMessage
                }
            };

            GitPullRequest updatedPullrequest = gitHttpClient.UpdatePullRequestAsync(
                pullRequestWithAutoCompleteEnabled, 
                pullRequest.Repository.Id, 
                pullRequest.PullRequestId).Result;

            return updatedPullrequest;
        }
    }
}
