Asp.net mvc 如何使用itext和asp mvc预览pdf

下面的代码创建了一个pdf，在您按下link/按钮后下载。 如何使pdf在浏览器中打开而不自动下载

'
    ' GET: /PDF

    Function Index() As FileResult
        Dim filestream As Stream = generatePDF()

        HttpContext.Response.AddHeader("content-disposition", "attachment; filename=Lijstmetmensenenmiddelen.pdf")

        Return New FileStreamResult(filestream, "application/pdf")
    End Function

    Private Function generatePDF() As Stream
        '' magic will happen here
        Dim memStream As MemoryStream = New MemoryStream()
        Dim doc As New Document()
        PdfWriter.GetInstance(doc, Response.OutputStream)

        doc.AddCreationDate()

        doc.Open()

        Dim para As New Paragraph()

        para.Add("Dit is een paragrafstring balbalbalal")

        doc.Add(para)

        doc.Close()


        Return memStream

    End Function

在这个博客上找到了答案：

应该是

HttpContext.Response.AddHeader("content-disposition", "Inline; filename=Lijstmetmensenenmiddelen.pdf")

HttpContext.Response.AddHeader("content-disposition", "Inline; filename=Lijstmetmensenenmiddelen.pdf")
