C#

public bool IsDeleted { get; }

屬性值

Boolean

如果已刪除列印工作，則為 true，否則為 false。

範例

下列範例示範如何在診斷列印作業的問題時使用這個屬性。

C#

// Check for possible trouble states of a print job using its properties
internal static void SpotTroubleUsingProperties(PrintSystemJobInfo theJob)
{
    if (theJob.IsBlocked)
    {
        Console.WriteLine("The job is blocked.");
    }
    if (theJob.IsCompleted || theJob.IsPrinted)
    {
        Console.WriteLine("The job has finished. Have user recheck all output bins and be sure the correct printer is being checked.");
    }
    if (theJob.IsDeleted || theJob.IsDeleting)
    {
        Console.WriteLine("The user or someone with administration rights to the queue has deleted the job. It must be resubmitted.");
    }
    if (theJob.IsInError)
    {
        Console.WriteLine("The job has errored.");
    }
    if (theJob.IsOffline)
    {
        Console.WriteLine("The printer is offline. Have user put it online with printer front panel.");
    }
    if (theJob.IsPaperOut)
    {
        Console.WriteLine("The printer is out of paper of the size required by the job. Have user add paper.");
    }

    if (theJob.IsPaused || theJob.HostingPrintQueue.IsPaused)
    {
        HandlePausedJob(theJob);
        //HandlePausedJob is defined in the complete example.
    }

    if (theJob.IsPrinting)
    {
        Console.WriteLine("The job is printing now.");
    }
    if (theJob.IsSpooling)
    {
        Console.WriteLine("The job is spooling now.");
    }
    if (theJob.IsUserInterventionRequired)
    {
        Console.WriteLine("The printer needs human intervention.");
    }
}//end SpotTroubleUsingProperties

備註

一開始，物件可能會將其自己的狀態回報為已刪除，但請記住 PrintSystemJobInfo ，物件只 代表 實際的列印作業。 從其列印佇列中刪除後者並不會自動處置 PrintSystemJobInfo 應用程式中的物件。 同樣地，物件不會從它所代表的列印作業刪除之前建立的任何 PrintJobInfoCollection 物件移除。 例如，如果在 GetPrintJobInfoCollection 刪除列印作業之前執行 方法，傳回的集合將會包含 PrintSystemJobInfo 代表列印作業的物件。 刪除列印作業時，不會從集合中移除這個物件。 GetPrintJobInfoCollection但如果再次執行 ，則傳回的集合將不會有任何成員代表已刪除的列印作業。
