loading from array bytes

[Antonio Tedesco]

how do i upload the pdf directly from array bytes?

 Dim jsonResult As Dictionary(Of String, String)

            Dim helper As New PdfViewerHelper()

            Dim docBytes = System.IO.File.ReadAllBytes(HttpContext.Current.Server.MapPath("~/TmpF/uno.pdf"))

            Dim docBase64 As String = Convert.ToBase64String(docBytes)

            Dim byteArray() As Byte = Convert.FromBase64String(docBase64)

            Dim stream As New MemoryStream(byteArray)

            helper.Load(stream)

            Return JsonConvert.SerializeObject(helper.ProcessPdf(jsonResult))

Hi Antonio ,  

Thank you for contacting Syncfusion Support. 

We can load the PDF document as byteArray in the PDF Viewer from the server side using the Load() API in the WebAPI controller. Please find the code snippet from the below, 

Private viewerHelper As New PdfViewerHelper() 

Dim docBytes = System.IO.File.ReadAllBytes(HttpContext.Current.Server.MapPath("~/Data/PdfViewer/HTTP Succinctly.pdf")) 

viewerHelper.Load(docBytes) 

We have created the sample for the same and shared in the following location,

Please find the below KB link for reference,
