memorystream

The following code will always throw UnuthorizedAccessException (MemoryStream's internal buffer cannot be accessed.) byte[] buf1 = { 2, 3, 5, 7, 11 }; var ms = new MemoryStream(buf1); byte[] buf2 = ms.GetBuffer(); // exception will be thrown here This is in a plain old console app and I'm running as an admin. I can't imagine a more privileged setting I could give this code. So why can't I get at this buffer? (And if nobody can, what's the point of the GetBuffer method?) The MSDN docs say To create a MemoryStream instance with a publicly visible buffer, use MemoryStream, MemoryStream(array[],

With the sharpPDF library I generate a pdf memory stream, and I want to send it directly via email. But the line ms.Seek(.... gives an ObjectDisposedException; Cannot access a closed Stream. The pdf.CreatePDF method takes either an (output) fileName string, or an (out)Stream. But I guess it also closes the stream? I'm not used to work much with streams, so if you could please advise how it should be done? The sharpPDF source code of the CreatePDF method can be found here: http://www.java2s.com/Open-Source/CSharp/PDF/SharpPDF/sharpPDF/pdfDocument.cs.htm Public Sub SendPDF() Dim pdf As New

The following code works, but I'm wondering if the MemoryStream created is closed properly. How should this be performed or does FileStreamResult handle it for me? public FileStreamResult DownloadBudgetedRoleOpportunities( Guid projectGuid, IEnumerable<Guid> guidRequiredRoles) { var rolebroker = new ProjectRoleBudgetBroker(); var memstream = rolebroker.CreateBudgetedRoleOpportunies( projectGuid, guidRequiredRoles); var fsr = new FileStreamResult ( memstream, "application/csv" ) { FileDownloadName = "RoleOpportunities.csv" }; // memstream.Close(); throws exception return fsr; } The

is it possible to get a pdf stream created by wkhtmltopdf from any html file and popup a download dialog in IE/Firefox/Chrome etc.? At the moment I get my outputstream by this code: public class Printer { public static MemoryStream GeneratePdf(StreamReader Html, MemoryStream pdf, Size pageSize) { Process p; StreamWriter stdin; ProcessStartInfo psi = new ProcessStartInfo(); psi.FileName = @"C:\PROGRA~1\WKHTML~1\wkhtmltopdf.exe"; // run the conversion utility psi.UseShellExecute = false; psi.CreateNoWindow = true; psi.RedirectStandardInput = true; psi.RedirectStandardOutput = true; psi

I have noticed two different approaches to writing out data to an XML file (error handling omitted for brevity). The first method has you build the XML document and then simply save the XML to a file: using (XmlWriter writer = XmlWriter.Create(fileName)) { writer.WriteStartDocument(true); writer.WriteStartElement("parentelement"); writer.WriteEndElement(); writer.WriteEndDocument(); } The second method has you create a MemoryStream, and then save the MemoryStream to a file: XmlWriterSettings settings = new XmlWriterSettings(); settings.Indent = true; MemoryStream ms = new MemoryStream(); using

I'm using the below sample code for writing and downloading a memory stream to a file in C#. MemoryStream memoryStream = new MemoryStream(); TextWriter textWriter = new StreamWriter(memoryStream); textWriter.WriteLine("Something"); byte[] bytesInStream = new byte[memoryStream.Length]; memoryStream.Write(bytesInStream, 0, bytesInStream.Length); memoryStream.Close(); Response.Clear(); Response.ContentType = "application/force-download"; Response.AddHeader("content-disposition", "attachment; filename=name_you_file.xls"); Response.BinaryWrite(bytesInStream); Response.End(); I am getting the
