ProjectContext.WaitForQueue 方法

等待指定的队列作业要完成,或等待的最大秒数。

命名空间:  Microsoft.ProjectServer.Client
程序集:  Microsoft.ProjectServer.Client(位于 Microsoft.ProjectServer.Client.dll 中)

语法

声明
Public Function WaitForQueue ( _
    job As QueueJob, _
    timeoutSeconds As Integer _
) As JobState
用法
Dim instance As ProjectContext
Dim job As QueueJob
Dim timeoutSeconds As Integer
Dim returnValue As JobState

returnValue = instance.WaitForQueue(job, _
    timeoutSeconds)
public JobState WaitForQueue(
    QueueJob job,
    int timeoutSeconds
)

参数

  • timeoutSeconds
    类型:System.Int32

    最大等待队列作业完成的秒数。

返回值

类型:Microsoft.ProjectServer.Client.JobState
队列作业的状态。如果作业成功完成后,会返回JobState.Success

示例

名为QueueCreateProject的控制台示例执行以下作业:

  • 分析命令行来获取的新的项目和一个可选的队列作业等待时间的名称。默认等待时间为 10 秒。例如,如果在Project Web App中不存在名为1 的测试项目的项目,您可以使用QueueCreateProject -projName "Test proj 1"命令来运行应用程序。

  • 创建ProjectContext对象的指定的Project Web App实例。

  • 获取名为"基本项目计划"的企业项目类型 (EPT) 的 GUID。

  • 创建一个项目,通过使用CreateTestProject方法,它将ProjectCreationInformation对象的属性设置。

  • 若要发布新的项目,通过使用ProjectContext.WaitForQueue方法的项目服务器队列服务将等待。

  • 列出已发布的项目。QueueCreateProject应用程序不调用WaitForQueue方法时,如果已发布的项目可能尚未包含新项目。
