我在此處有此代碼可將創建的XtraReport導出爲PDF文件。但是我收到一條錯誤消息，指出「它正在被另一個進程使用」。導出爲PDF（XTRAReport DevExpress）錯誤：正在被另一個進程使用
有沒有辦法讓我避免這個錯誤？我試圖通過使用System.IO.File.Delete刪除文件，但它不斷收到錯誤消息。另外，考慮到我真的需要使用相同的文件名。
下面的代碼：
Dim ReturnText As String = ""
Dim dtReport As DataTable = Nothing
Dim dtRows() As DataRow = Nothing
Dim XRPath As String = "reports/travel.repx"
Dim XRSubPath As String = "reports/travel_costallocation.repx"
Dim SQL As String = String.Empty
Dim xrBandTag As String = String.Empty
Dim xrGroupField As GroupField = Nothing
Dim xrProtectBands As String = "[BottomMargin][PageFooter][PageHeader][ReportHeader]"
Dim xrFilename As String = String.Empty
Dim xParams As Integer = 0
Dim dAccessTo As DataTable = Nothing
Dim bUpdate As Boolean = False
Dim ReportID As Integer = 0
Dim ReportData() As Object = Nothing
Dim Value() As String = Nothing
Dim xrReport As XtraReport = Nothing
'manipulate report here
xrReport.ExportToPdf(ServerPath & "\documents\travelpdf\eTravelNo_" & PathID & ".pdf")
謝謝你的幫助提前。
