使用CSOM创建新的Projectserver项目时，如何为企业客户字段填写值

Question

我想使用C＃中的CSOM创建一个新项目（内部为Projectserver 2013）。 我可以创建新项目。如果要在企业自定义字段中填写值，则必须再次从服务器加载已保存的项目，并在自定义字段中填写。 （请参见源代码）。 但是对于我的要求，新项目将需要自定义字段。有没有一种方法可以发送请求中创建项目的自定义字段的值？

var projectCreationInformation = new ProjectCreationInformation();
projectCreationInformation.Id = Guid.NewGuid();
projectCreationInformation.Name = projectData.ProjectTitle;
projectCreationInformation.Description = "";
projectCreationInformation.EnterpriseProjectTypeId =   GetEptUid("test_Csom");
projectCreationInformation.Start = DateTime.Today.Date;
PublishedProject newPublishedProj = ProjectContext.Projects.Add(projectCreationInformation);
QueueJob qJob = ProjectContext.Projects.Update();

JobState jobState = ProjectContext.WaitForQueue(qJob, 180);
if (jobState == JobState.Success)
    {
        ProjectContext.Load(ProjectContext.Projects, c => c.IncludeWithDefaultProperties(pr => pr.CustomFields));
        ProjectContext.ExecuteQuery();
        var projects = ProjectContext.LoadQuery(ProjectContext.Projects.Where(p => p.Id == projectCreationInformation.Id));
        ProjectContext.Load(ProjectContext.CustomFields);                
        ProjectContext.ExecuteQuery();
        DraftProject draftProject = projects.First().Draft;
        JobState job1 = ProjectContext.WaitForQueue(draftProject.CheckIn(true), 30);
        DraftProject projectCheckout = projects.First().CheckOut();
        CustomField projCF = ProjectContext.CustomFields.FirstOrDefault(cf => cf.Name == "Test_ECF");
        projectCheckout.SetCustomFieldValue(projCF.InternalName, "Test");
        projectCheckout.Update();
        ProjectContext.Load(projectCheckout);
        projectCheckout.Publish(true);
        ProjectContext.ExecuteQuery();
        ProjectContext.Projects.Update();
        ProjectContext.ExecuteQuery();
    }
