I want to create a download and install ipa file automatically function in to iphone/ipad in C# ?But i have no idea how to do it.I only use a command way to download the file but it wont install into my iphone/ipad automatically?Is that possible do in C#?
It wrong code just an ideal for it:
protected void Page_Load(object sender, EventArgs e)
{
string filePath = string.Empty;
string appType = string.Empty;
//ios
filePath = "appFile/Apps.ipa";
appType = "application/octet-stream";
Response.ClearContent();
Response.ContentType = MimeType(Path.GetExtension(fName),appType);
Response.AddHeader("Content-Disposition", string.Format("attachment; filename = {0}",System.IO.Path.GetFileName(fName)));
Response.AddHeader("Content-Length", sz.ToString("F0"));
Response.TransmitFile(fName);
Response.End();
}
public static string MimeType(string Extension,string appMineType)
{
string mime = appMineType;
if (string.IsNullOrEmpty(Extension))
return mime;
string ext = Extension.ToLower();
Microsoft.Win32.RegistryKey rk = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext);
if (rk != null && rk.GetValue("Content Type") != null)
mime = rk.GetValue("Content Type").ToString();
return mime;
}

I am trying to call a method to view a PDF
I am attempting to call the method from the URL eg. /Home.aspx/ViewPDF
The ViewPDF in the url is the method in the Home.aspx file.
I am new to ASP and this has stumped me, thanks if you can provide any help
EDIT 1:
I have an asp button with this in it's click method and it works:
protected void test12_Click(object sender, EventArgs e)
{
string FilePath = Server.MapPath("/Tasks/Content/54874/dummy.pdf");
WebClient User = new WebClient();
Byte[] FileBuffer = User.DownloadData(FilePath);
if (FileBuffer != null)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-length", FileBuffer.Length.ToString());
Response.BinaryWrite(FileBuffer);
}
}
How would I be able to make the same thing happen from visiting /Home.aspx/ViewPDF
with /ViewPDF being a method inside the code behind of Home.aspx
I believe the method needs to be static to be able to view it from the url is there any alternative for defining the file path as Server.MapPath is not static.
I have made a test method in Home.aspx:
[WebMethod]
[ScriptMethod(UseHttpGet = true)]
public static string test(object sender, EventArgs e)
{
return "test";
}
But when I visit /Home.aspx/test it just loads a version of the page with no images and slightly off css
Thanks for any help
Edit 2 / Solution:
After doing a bit of looking around on google you can easily implement MVC into web forms
https://www.davepaquette.com/archive/2013/12/30/so-you-inherited-an-asp-net-web-forms-application.aspx
From that I made a controller
public FileResult GetTaskAttatchment()
{
string ReportURL = Server.MapPath("/Tasks/Content/54874/dummy.pdf");
byte[] FileBytes = System.IO.File.ReadAllBytes(ReportURL);
return File(FileBytes, "application/pdf");
}
Which now works perfectly, Thanks again for all the help
//check your datatype for attachment shuld be varbinary...
protected void btnfinalupload_Click(object sender, EventArgs e)
{
string filename = "";
string filenameret = "";
using (DataSet ds = GetFormForDownload(id,finid))
{
if (ds.Tables[0].Rows.Count > 0)
{
filenameret = ds.Tables[0].Rows[0]["attachment"].ToString().Trim();
filename = ds.Tables[0].Rows[0]["filename"].ToString().Trim();
byte[] bytes;
string fileName, contentType;
bytes = (byte[])ds.Tables[0].Rows[0]["attachment"];
contentType = "application/pdf";
fileName = filename;
Response.Clear();
Response.Buffer = true;
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = contentType;
Response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName);
Response.BinaryWrite(bytes);
Response.Flush();
Response.End();
}
}
}
I have been trying to write a code to download file from the server, the path is correct but the file isn't downloading when I click it.
The delete code works properly which looks like this:
protected void DeleteFile(object sender, EventArgs e)
{
string filePath = (sender as LinkButton).CommandArgument;
File.Delete(filePath);
GenerateDownloadLinks();
}
However the download isn't starting the download (debugging runs through entire code):
protected void ButtonDownload_Click(object sender, EventArgs e)
{
string path = (sender as LinkButton).CommandArgument;
string name = Path.GetFileName(path);
string ext = Path.GetExtension(path);
HttpResponse response = HttpContext.Current.Response;
response.ClearContent();
response.Clear();
response.AddHeader("content-disposition",
"attachment; filename=" + name);
response.ContentType = "text/plain";
response.TransmitFile(path);
response.Flush();
response.End();
}
The file I am downloading is a .dat file. I tried changing and adding the configurations but with no luck
Problem was update panel related, my datalist was inside an update panel
I have one ActionUrl in application in that it contains address of files of all formats.
Now on click of any file it should be open in browser(Not to download)
I tried bellow code for it but its only working for pdf format.
public FileContentResult ViewFile(string filename)
{
string OnlyFileName = Path.GetFileName(filename);
string ext = Path.GetExtension(filename);
var mimeType = "application/pdf";
if (ext.ToLower() == ".png")
{
mimeType = "image/png";
}
else if (ext.ToLower() == ".docx")
{
mimeType = "application/ms-word";
}
//
var fileContents = System.IO.File.ReadAllBytes(filename);
return new FileContentResult(fileContents, mimeType);
}
i have a handler for download files like below :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IO;
using NiceFileExplorer.Classes;
namespace NiceFileExplorer
{
/// <summary>
/// Summary description for HandlerForMyFE
/// </summary>
public class HandlerForMyFE : IHttpHandler, System.Web.SessionState.IRequiresSessionState
{
private HttpContext _context;
private HttpContext Context
{
get
{
return _context;
}
set
{
_context = value;
}
}
public void ProcessRequest(HttpContext context)
{
Context = context;
string filePath = context.Request.QueryString["Downloadpath"];
filePath = context.Server.MapPath(filePath);
if (filePath == null)
{
return;
}
System.IO.StreamReader streamReader = new System.IO.StreamReader(filePath);
System.IO.BinaryReader binaryReader = new System.IO.BinaryReader(streamReader.BaseStream);
byte[] bytes = new byte[streamReader.BaseStream.Length];
binaryReader.Read(bytes, 0, (int)streamReader.BaseStream.Length);
if (bytes == null)
{
return;
}
streamReader.Close();
binaryReader.Close();
string fileName = System.IO.Path.GetFileName(filePath);
string MimeType = GetMimeType(fileName);
string extension = System.IO.Path.GetExtension(filePath);
char[] extension_ar = extension.ToCharArray();
string extension_Without_dot = string.Empty;
for (int i = 1; i < extension_ar.Length; i++)
{
extension_Without_dot += extension_ar[i];
}
string filesize = string.Empty;
FileInfo f = new FileInfo(filePath);
filesize = f.Length.ToString();
if (HttpContext.Current.Session["User_ID"] != null)
{
WriteFile(bytes, fileName, filesize, MimeType + " " + extension_Without_dot, context.Response);
}
}
private void WriteFile(byte[] content, string fileName, string filesize, string contentType, HttpResponse response)
{
response.Buffer = true;
response.Clear();
response.ContentType = contentType;
response.AddHeader("content-disposition", "attachment; filename=" + fileName);
response.AddHeader("Content-Length", filesize);
response.BinaryWrite(content);
response.Flush();
response.End();
}
private string GetMimeType(string fileName)
{
string mimeType = "application/unknown";
string ext = System.IO.Path.GetExtension(fileName).ToLower();
Microsoft.Win32.RegistryKey regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext);
if (regKey != null && regKey.GetValue("Content Type") != null)
mimeType = regKey.GetValue("Content Type").ToString();
return mimeType;
}
public bool IsReusable
{
get
{
return false;
}
}
}
}
the important part of this handler is WriteFile And It works perfect!
i call this handler for download a file from code behind like below :
Response.Redirect("~/Handler.ashx?Downloadpath=" + HttpUtility.UrlEncode(DownloadPath));
one of my download links in my web site is like below :
http://localhost:5410/en/Download.aspx?Downloadpath=%2fFiles%2f%2fsamsung%2fGE2550_DEFAULT_MDL_V002.exe
so, i can contorl my download links easily by that handler!
my problem is when some body changes that link to :
http://localhost:5410/Files/samsung/GE2550_DEFAULT_MDL_V002.exe
can download that file directly without that handler!
how can i prevent this direct download?
thanks in advance
First, putting the actual physical path to the file into the querystring is not really a good idea. Gives a bit too much information to the public, and opens you to security issues with people putting unexpected paths into the url to try and download other files.
With that said, regarding you problem above, you should either put your Files folder outside of the web root so that it is inaccessible from the browser, or setup IIS so that no one is allowed access to that folder (and subfolders). As long as the account that ASP.NET runs under has permissions to the folder, you will still be able to open the file in your code and write it to the response, regardless of whether it's visible through IIS.
plz see the below handler :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace FileExplorer
{
/// <summary>
/// Summary description for HandlerForMyFE
/// </summary>
public class HandlerForMyFE : IHttpHandler, System.Web.SessionState.IRequiresSessionState
{
private HttpContext _context;
private HttpContext Context
{
get
{
return _context;
}
set
{
_context = value;
}
}
public void ProcessRequest(HttpContext context)
{
Context = context;
string filePath = context.Request.QueryString["Downloadpath"];
filePath = context.Server.MapPath(filePath);
if (filePath == null)
{
return;
}
System.IO.StreamReader streamReader = new System.IO.StreamReader(filePath);
System.IO.BinaryReader br = new System.IO.BinaryReader(streamReader.BaseStream);
byte[] bytes = new byte[streamReader.BaseStream.Length];
br.Read(bytes, 0, (int)streamReader.BaseStream.Length);
if (bytes == null)
{
return;
}
streamReader.Close();
br.Close();
string fileName = System.IO.Path.GetFileName(filePath);
string MimeType = GetMimeType(fileName);
string extension = System.IO.Path.GetExtension(filePath);
char[] extension_ar = extension.ToCharArray();
string extension_Without_dot = string.Empty;
for (int i = 1; i < extension_ar.Length; i++)
{
extension_Without_dot += extension_ar[i];
}
//if (extension == ".jpg")
//{ // Handle *.jpg and
// WriteFile(bytes, fileName, "image/jpeg jpeg jpg jpe", context.Response);
//}
//else if (extension == ".gif")
//{// Handle *.gif
// WriteFile(bytes, fileName, "image/gif gif", context.Response);
//}
WriteFile(bytes, fileName, MimeType + " " + extension_Without_dot, context.Response);
}
private void WriteFile(byte[] content, string fileName, string contentType, HttpResponse response)
{
response.Buffer = true;
response.Clear();
response.ContentType = contentType;
response.AddHeader("content-disposition", "attachment; filename=" + fileName);
response.BinaryWrite(content);
response.Flush();
response.End();
}
private string GetMimeType(string fileName)
{
string mimeType = "application/unknown";
string ext = System.IO.Path.GetExtension(fileName).ToLower();
Microsoft.Win32.RegistryKey regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext);

i wrote that handler for direct download file after clicking without opening that file in browser...
it seems the upper codes work!
but there is a problem for showing file size during download.
for test that plz see the below link :
Test with internet download manager
in that link we do n't have file size, but in the link below we have it :
another link
what is the problem of my handler and how can i fix this issue?
thanks in advance
I have not run this code. Here is another way of transmitting the file.
Try this code:
//context = HttpContext
context.Response.Clear();
context.Response.ContentType = varMimeType;
context.Response.TransmitFile(filePath);
context.Response.AddHeader("content-disposition", "attachment;filename=" + varFileName);
context.Response.AddHeader("Content-Length", filePathFileInfo.Length);
context.Response.Flush();
context.Response.End();
