how to show pdf in new windows from local path

I have converted a rpt file to pdf and saved it in a local system path via web.config and trying to open the pdf file after saving it , from the saved location. I am able to save it in the required folder and able to redirect the folder path to the new windows , but the folder path is appearing with out the '\' and with drive letter as small case
this is my code
var clsPrepareFile = new clsPrepareFile(General.ConnString());
dsUserMatrixReport = clsPrepareFile.UserGroupReport(sValue);
if (dsUserMatrixReport != null && dsUserMatrixReport.Tables.Count > 1 && dsUserMatrixReport.Tables[0].Rows.Count > 0 && dsUserMatrixReport.Tables[1].Rows.Count > 0)
// if (dsUserMatrixReport != null )
{
dsUserMatrixReport.Tables[0].TableName = "Inward_Report1";
dsUserMatrixReport.Tables[1].TableName = "UserStatus";
var rptDocument = new ReportDocument();
//rptDocument.SummaryInfo.ReportTitle = "Inward_Report_" + txtFromDate.Text.Replace("/", "") + "_" + txtToDate.Text.Replace("/", "");
CrystalReportViewer1.Visible = true;
//CrystalReportViewer1.ID = "Inward_Report_" + txtFromDate.Text.Replace("/", "") + "_" + txtToDate.Text.Replace("/", "");
rptDocument.Load(Server.MapPath("~\\Report\\UserGroupReport.rpt"));
rptDocument.SetDataSource(dsUserMatrixReport);
Session.Add("CR_Session", rptDocument);
CrystalReportViewer1.ReportSource = rptDocument;
string filePath = ConfigurationManager.AppSettings["ReportPdfPath"].ToString();
string filename = "UserGroupReport" + DateTime.Now.ToString("yyyyMMdd") + ".pdf";
string pdfname = filePath + filename;
rptDocument.ExportToDisk(ExportFormatType.PortableDocFormat, pdfname);
ScriptManager.RegisterClientScriptBlock(this.Page, typeof(string), "newwindow", "window.open('" + pdfname + "', '_blank')", true);
the script manager is redirecting to anew page and the url appears like this
"c:GeneratedPDFUserGroupReport20200415.pdf"

Access to the path 'Enrollments.zip' is denied, After running Background service running

After I restart my PC, my background service works fine. If I reinstalled or made any changes to the DB, my PC access path ".zip" denied. one more thing same background is running in another PC.
Two background services running in two different PCs to exchange the data.

A few things that you can look at.
First, use the using statement to create the archive, that will make sure that it gets disposed.
Second, why do you check if the file exists, delete it, then create it with ZipFile just to Write it with File? Look at this
Third, use Path class. It will make sure that all your backslashed is correct, and it looks neater.
Fourth, check if a file can be created in the folder
Check if this code gives you the same result.
public void ConvertIntoZipAndMoveToBackUp(string localPath, string fileName, byte[] zipByteResponse, string code)
{
string Destinationpath = Path.Combine(ConfigurationManager.AppSettings["OtherEnrollmentsBackUpPath"], code);
try
{
fileName = Path.GetFileNameWithoutExtension(fileName) + DateTime.Now.ToString("yyyy-MM-dd_hh-mm-ss.fff") + ".zip"; //This will ensure that you have a unique filename to create
File.WriteAllBytes(Path.Combine(localPath, fileName), zipByteResponse);
lgmr.Log(string.Concat(serviceName, " ", code, ": Zip File Created and Downloaded from the WebAPI Response", Path.Combine(localPath, fileName)), LoggingManager.LogType.Info);
using (var archive = ZipFile.OpenRead(Path.Combine(localPath, fileName)))
{
ecount = archive.Entries.Count(x => !string.IsNullOrWhiteSpace(x.Name));
strECount = ecount.ToString();
lgmr.Log(string.Concat(serviceName, " ", code, ": Files Count: ",ecount, localPath + "\\" + fileName), LoggingManager.LogType.Info);
foreach (ZipArchiveEntry entry in archive.Entries)
{

}

how to create .txt file and write it c# asp.net

I am trying create and write to a text file in a C# application using the following code
System.IO.Directory.CreateDirectory(Server.MapPath("~\\count"));
using (System.IO.FileStream fs = new System.IO.FileStream("~/count/count.txt", System.IO.FileMode.Create))
using (System.IO.StreamWriter sw = new System.IO.StreamWriter("~/count/count.txt"))
{
sw.Write("101");
}
string _count = System.IO.File.ReadAllText("~/count/count.txt");
Application["NoOfVisitors"] = _count;
but I get an error:
The process cannot access the file 'path' because it is being used by another process.
What is my error?

You're trying to open the file twice; your first using statements creates a FileStream that is not used, but locks the file, so the second using fails.
Just delete your first using line, and it should all work fine.
However, I'd recommend replacing all of that with File.WriteAllText, then there would be no using in your code, it'd be much simpler.
var dir = Server.MapPath("~\\count");
var file = Path.Combine(dir, "count.txt");
Directory.CreateDirectory(dir);
File.WriteAllText(file, "101");
var _count = File.ReadAllText(file);
Application["NoOfVisitors"] = _count;

Change filename on file upload in .net (asp)

How to change file name on upload ?
I have such code :
<%# WebHandler Language="C#" Class="Upload" %>
using System;
using System.Web;
using System.IO;
public class Upload : IHttpHandler {
public void ProcessRequest(HttpContext context) {
HttpPostedFile oFile = context.Request.Files["Filedata"];
string newFileName1 = HttpContext.Current.Server.MapPath(#context.Request["orderID"]);
string newFileName2 = HttpContext.Current.Server.MapPath(#context.Request["productCombinationString"]);
string newName;
if(newFileName2 != "" && newFileName2 != null && newFileName2 != "<!--#Ecom:productCombinationString-->") {
newName = newFileName1 + newFileName2 + oFile.ContentType;
} else {
newName = newFileName1 + oFile.ContentType;
}
string sDirectory = HttpContext.Current.Server.MapPath(#context.Request["folder"]);
oFile.SaveAs(sDirectory + "/" + oFile.FileName);
if (!Directory.Exists(sDirectory)) Directory.CreateDirectory(sDirectory);
context.Response.Write("1");
}
public bool IsReusable {
get { return false; }
}
}
And if i change oFile.Filename to newName it does not work ... what is the problem ? :)
Thank you

You can pass your Custom File Name along with Directory to SaveAs Method
oFile.SaveAs(sDirectory + "/" + "abc");

try:
// Get the extension of the uploaded file.
string fileName = Server.HtmlEncode(FileUpload1.FileName);
string extension = System.IO.Path.GetExtension(fileName);
string newName;
if(newFileName2 != "" && newFileName2 != null && newFileName2 != "<!--#Ecom:productCombinationString-->") {
newName = newFileName1 + newFileName2 + extension ;
} else {
newName = newFileName1 + extension ;
}
oFile.SaveAs(sDirectory + "/" + newName );

I haven't tried this code but I do want to point out two things of from the original code:
The first is this order of operations:
oFile.SaveAs(sDirectory + "/" + oFile.FileName);
if (!Directory.Exists(sDirectory)) Directory.CreateDirectory(sDirectory);
I believe it should be this instead. In the above sequence, there is a potential edge case of saving into a non-existing folder. This ensures that the folder is created:
if (!Directory.Exists(sDirectory))
{
Directory.CreateDirectory(sDirectory);
}
oFile.SaveAs(sDirectory + "/" + oFile.FileName);
The other thing is that you might be running into issues with / as the path separator. I think it should be much safer to do something like:
var saveLocation = Path.Combine(sDirectory, oFile.FileName);
oFile.SaveAs(saveLocation);
I hope this helps!

Here is an example i used when saving an image look at the save as section
////saving file in the physical folder;
FileUpload FileUpload1 = file_Image;
string virtualFolder = "~/Resourceimages/";
string physicalFolder = HostingEnvironment.MapPath(virtualFolder);
string PhotoName = ((string)Session["UserName"] + (string)Session["UserSurname"]);
FileUpload1.SaveAs(physicalFolder + PhotoName + FileUpload1.FileName);
string location = virtualFolder + PhotoName + FileUpload1.FileName;
webservice.UpdateResourceImage((int)Session["UserID"], location);
lbl_Result.Text = "Your file " + FileUpload1.FileName + " has been uploaded.";
Image1.Visible = true;
Image1.ImageUrl = location;

string uploadFolder = Request.PhysicalApplicationPath + "UploadFile\\";
if (FileUpload1.HasFile)
{
string extension = Path.GetExtension(FileUpload1.PostedFile.FileName);
FileUpload1.SaveAs(uploadFolder + "Test"+ extension);
Label1.Text = "File uploaded successfully as: " + "Test"+ extension;
}
else
{
Label1.Text = "First select a file.";
}
