ProjectCollection class

Office 2013

Represents a collection of PublishedProject objects.

Namespace:  Microsoft.ProjectServer.Client
Assembly:  Microsoft.ProjectServer.Client (in Microsoft.ProjectServer.Client.dll)

[ScriptTypeAttribute("PS.ProjectCollection", ServerTypeId = "{8d842010-5471-4748-ab8a-ed6df0494f3d}")]
public class ProjectCollection : ClientObjectCollection<PublishedProject>

To check out a published project for editing, use the PublishedProjectCheckOut() method.

Project Server creates a virtual PublishedProject object for each draft project that has not yet been published. A virtual published project ensures that a draft project can be retrieved through the ProjectCollection object, whether it has been published or not. A retrieved project gets properties from the draft tables in the Project database.

For example, if you create a draft project with the PSI, and then read all projects with the CSOM, the ProjectCollection object contains the unpublished draft project. You can determine whether a project has been published by the value of the PublishedProject.LastPublishedDate property, which is inherited from Project.LastPublishedDate. For an unpublished project, the LastPublishedDate property value is DateTime.Min (1/1/0001). The following CSOM code fragment creates a draft project but does not persist or publish it.

ProjectContext projContext = new ProjectContext("http://ServerName/pwa");
ProjectCreationInformation newProj = new ProjectCreationInformation();

newProj.Id = Guid.NewGuid();
newProj.Name = "Test project not published";
newProj.Start = DateTime.Today.Date;

PublishedProject newPublishedProj = projContext.Projects.Add(newProj);

projContext.Load(newPublishedProj);
projContext.ExecuteQuery();

DateTime pubDate = newPublishedProj.LastPublishedDate;
Console.Write("\n\tLastPublishedDate before publishing: {0}", pubDate.ToString());

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
