Wie speichert man Dateien/Daten im Anwendungsordner in MVC?

Question

Ich verwende eine Bibliothek zum Konvertieren von HTML in PDF. Nach dem Konvertieren in PDF Wie kann ich diese konvertierte PDF-Datei im Anwendungsordner in einem Controller speichern? Hier ist der Code:

public ActionResult ABC(ResearchProposal model) 
{ 
    ViewDataDictionary viewData = new ViewDataDictionary(model); 

    // transmit the posted data to view 
    viewData["MyModel"] = model; 

    StringWriter stringWriter = new StringWriter(); 

    // Render the Index view in a HTML string 
    ViewEngineResult viewResult = ViewEngines.Engines.FindView(ControllerContext, "ABC", null); 
    ViewContext viewContext = new ViewContext(
      ControllerContext, 
      viewResult.View, 
      viewData, 
      new TempDataDictionary(), 
      stringWriter 
      ); 
    viewResult.View.Render(viewContext, stringWriter); 

    // Get the view HTML string 
    string htmlToConvert = stringWriter.ToString(); 

    // Get the base URL 
    String currentPageUrl = this.ControllerContext.HttpContext.Request.Url.AbsoluteUri; 
    String baseUrl = currentPageUrl.Substring(0, currentPageUrl.Length - "Reports/ABC".Length); 

    // Create a HTML to PDF converter object with default settings 
    HtmlToPdfConverter htmlToPdfConverter = new HtmlToPdfConverter(); 

    // Set license key received after purchase to use the converter in licensed mode 
    // Leave it not set to use the converter in demo mode 
    htmlToPdfConverter.LicenseKey = "fvDh8eDx4fHg4P/h8eLg/+Dj/+jo6Og="; 

    // Set an adddional delay in seconds to wait for JavaScript or AJAX calls after page load completed 
    // Set this property to 0 if you don't need to wait for such asynchcronous operations to finish 
    htmlToPdfConverter.ConversionDelay = 2; 

    // Convert the HTML string to a PDF document in a memory buffer 
    byte[] outPdfBuffer = htmlToPdfConverter.ConvertHtml(htmlToConvert, baseUrl); 


    // Send the PDF file to browser 
    FileResult fileResult = new FileContentResult(outPdfBuffer, "application/pdf"); 

    fileResult.FileDownloadName = "Convert_Current_Page.pdf"; 

    return fileresult; 
} 

Answer 1

Sie File.WriteAllBytes verwenden können, um die Bytes des FileContentResult zu speichern, die Sie.

Sie müssen den relativen Pfad des Servers zuordnen, damit dies funktioniert, da der relative Pfad nur im Kontext von ASP.NET funktioniert.

string filename = "Convert_Current_Page.pdf"; 
string path = Server.MapPath("~G/Initial try/Content/data/"); 
path = Path.Combine(path, filename); 

File.WriteAllBytes(path, fileResult.FilecContents);
