PrintSystemJobInfo.IsDeleting 属性

定义

命名空间:

System.Printing

程序集:

System.Printing.dll

获取一个值，该值指示是否正在从打印队列中删除打印作业。

public:
 property bool IsDeleting { bool get(); };

public bool IsDeleting { get; }

member this.IsDeleting : bool

Public ReadOnly Property IsDeleting As Boolean

属性值

Boolean

如果正在删除打印作业，则为 true；否则为 false。

示例

以下示例演示如何在诊断打印作业问题时使用此属性。

// Check for possible trouble states of a print job using its properties
