recurrenceID As UInteger, _
sequence As UInteger, _
dateStamp As String, _
cancelMeeting As Boolean _

'用途
Dim instance As SPMeeting

Dim recurrenceID As UInteger
Dim sequence As UInteger
Dim dateStamp As String
Dim cancelMeeting As Boolean
instance.Cancel(uid, recurrenceID, sequence, _
dateStamp, cancelMeeting)
public void Cancel(
string uid,
uint recurrenceID,
uint sequence,
string dateStamp,
bool cancelMeeting
)
參數
uid
Type: System.Stringstring包含行事曆事件RFC 2445所指定的唯一識別碼 (UID)。如為週期性會議，每個會議執行個體共用一般 UID。為了區別週期性會議執行個體之間，每個執行個體也都會指定 RecurrenceID。
recurrenceID
Type: System.UInt32識別為週期性會議執行個體的值。單一執行個體會議時，傳遞 0。如為週期性會議，傳遞至會議執行個體，格式 YYYYMMDD 日期相對應的值。例如，識別為 2010 年 5 月 1 日排定週期性會議執行個體的值是 20100501。
sequence
Type: System.UInt32一個值，表示RFC 2445所指定的修訂順序編號。順序號碼是從零開始，以及每個版本遞增。序號用於判斷更新的順序，以防他們送達照順序。更新更低比目前序號，則會捨棄。
dateStamp
Type: System.Stringstring代表目前日期與時間。日期及時間必須以來表示以國際標準時間 (UTC) 格式指定由ISO 8601，如下："yyyyMMdd'T 'HHmmss' Z'"。
cancelMeeting
Type: System.Booleantrue如果您想要刪除的會議。
備註
Cancel方法不會刪除議程的項目、 文件或會議工作區網站中的會議相關聯的其他資訊。
Examples
下列範例會列舉目前網站下的所有工作區，並在每個工作區中，會取消排定在過去一次的每個會議的主控台應用程式。
