First of all I would like to say that I have not experience with the .NET framework. I've the following problem. From Javascript, I perform a call to an aspx page, which has the following c# code behind:
using System;
using Decoder;
namespace Decoder
{
public class PDF_Generator : System.Web.UI.Page
{
private string decodedPDF;
private string base64EncodedPDF;
Decoder.Decoder decoder = new Decoder();
protected void Page_Load(object sender, EventsArgs e)
{
try
{
this.base64EncodedPDF = Request.Params["encodedString"]; //get encoded string from js
this.decodedPDF = decoder.decodeFromBase64toString(this.base64EncodedPDF); //decode string
byte[] pdfByteStream = decoder.getBytesFromString(this.decodedPDF);
Response.Clear();
Response.ContentType = "application/pdf";
//Response.AddHeader("Content-Disposition", "attachment; filename=\"summary.pdf\"");
Response.AddHeader("Content-Length", pdfByteStream.Length.toString());
Response.BinaryWrite(pdfByteStream);
Response.End();
}
}
}
}
I would like to use my class Decoder.cs in PDF_Generator, but I receive the following error:
CS0234: The type or namespace 'Decoder' does not exist in the class or namespace 'Decoder' (are you missing an assembly reference?)
My aspx file is this:
<%@ Import Namespace="Decoder"%>
<%@ Page language="c#" src="Scipafi_PDF.aspx.cs" AutoEventWireup="true" Inherits="PDF_Generator" %>
Thanks in advance for all your advices.
You are importing the Decoder Namespace twice, once in your code behind ( using Decoder;
) and once in your aspx page ( <%@ Import Namespace="Decoder"%>
). I wonder if that may be the problem. Try removing
<%@ Import Namespace="Decoder"%>
from your aspx page.
If looks like you've re-written code for things that are already in the .Net framework. See System.Convert.ToBase64String()
and System.Convert.FromBase64String()
you should remove from the page
<%@ Import Namespace="Decoder"%>
and make Inherits="Decoder.PDF_Generator"
<%@ Page language="c#" src="Scipafi_PDF.aspx.cs" AutoEventWireup="true" Inherits="Decoder.PDF_Generator" %>
you also don't need in codebehind and can remove
using Decoder;
but this actually shouldn't raise errors
UPDATE
take a look at @Ryios comment, he is right
