What's the right way to copy a file in another folder?

I have to copy a certain file to another folder, and this has to happen when I click a button.
Now I have two problems: the file is not copied correctly, and the new folder with the new file is created after one or two minutes.
When i say copied incorrectly, I mean that -0.364384 becomes -0.365163223838319.
I'm currently using this script in my button (ps I have three buttons for files named 1.json 2.json and 3.json)
private string path = "Assets\\Modelli\\Sinc ";
public void salvaEs1()
{
if (Directory.Exists(path)) { Directory.Delete(path, true); }
Directory.CreateDirectory(path);
string fileToCopy = "Assets\\Modelli\\daMedico\\1.json";
string destinationDirectory = "Assets\\Modelli\\Sinc\\";
File.Copy(fileToCopy, destinationDirectory + "sinc.json");
}
Errors are about some code that I use to read the file. But the problem are the errors in the file, non the ones that come from them

How can I pass a file/file path from one Button_Click event to another in C#?

I have a fileupload control (FileUpload1) in my webform which I use to load an excel file. I use a button called btn_open to display it in a gridview on click.
I also save the file using FileUpload1.SaveAs() method in a server folder.
Now I have another button called btn_edit which on click needs to use the same
file that I just loaded to do another set of operations.
How do I pass this file/file path from btn_open_Click to btn_edit_Click? I do not want to specify the exact location on the code. There will be multiple times I will open new excel files so I don't want to specify the file path to the server for every new file.This needs to happen programatically. Also, I want to avoid using Interop if its possible.
The following code snippet might make things more clear as to what I want to do.
protected void btn_open_Click(object sender, EventArgs e)
{
string fileExtension = System.IO.Path.GetExtension(FileUpload1.FileName);
if (fileExtension.ToLower() == ".xlsx" || fileExtension.ToLower() == ".xls")
{
string path = Path.GetFileName(FileUpload1.FileName); //capture the file name of the file I have uploaded
path = path.Replace(" ", ""); // if there is any spacing between the file name it will remove it
FileUpload1.SaveAs(Server.MapPath("~/ExcelFile/") + path); //saves to Server folder called ExcelFile
String ExcelPath = Server.MapPath("~/ExcelFile/") + path; // Returns the physical file path that corresponds to the specified virtual path.
.
.
*code to display it in gridview*
.
.
}
else
{
Console.Writeline("File type not permissible");
}
}
protected void btn_edit_Click(object sender, EventArgs e)
{
//HOW DO I PASS THE ABOVE FILE HERE PROGRAMATICALLY WITHOUT SPECIFYING IT'S EXACT LOCATION ON THE SERVER??
}

Using Session variable helped me solve my problem. Hopefully it will be helpful to other people who might encounter similar issue.
On the first button (in my case btn_open_Click), add:
Session["myXlsPath"] = ExcelFilePath;
Note: "myXlsPath" is just a name I created for my Session variable. ExcelFilePath is the path of my excel file that I want to pass to the other button.
On the button you want to pass the file path to (in my case btn_edit_Click), add:
string ExcelFilePath = (string)Session["myXlsPath"];

Get full path from short file name

Can i get the full path from a filename such as get the full directory path from test.txt, Or is there a way i can save it
The reason im asking this is im making a application like Notepad++ some of you may of heard of it. When changing the tab control tab I want the form's text to be the full directory while the tabs text is just filename.format
My so far code
private void tabControl1_TabIndexChanged(object sender, EventArgs e)
{
if (tabControl1.SelectedTab.Text.StartsWith("New"))
{
int count = tabControl1.TabCount - 1;
this.Text = tabControl1.Controls[count].Text + " - My Note 1.0";
}
//It is a directory and i need to make the forms text the path here?
}

You can use System.IO.Path.GetFullPath:
var fullPath = Path.GetFullPath("test.txt");
If you pass in a short file name, it is expanded to a long file name.
If c:\temp\newdir is the current directory, calling GetFullPath on a file name such as test.txt returns c:\temp\newdir\test.txt.
And if you want to get path from that you use System.IO.Path.GetDirectoryName
var path = Path.GetDirectoryName(fullPath)

I think you should probably keep the full path and get the filename from the full path rather than the other way around. The key is to use a type representing a document, and let the tab view that document. If each tab refers to a document, and each document knows its full path, then you can get the short filename from the documents full path.
public class Document
{
public string FullPath { get; set; } // Full path to file, null for unsaved
public string FileName
{
get { return Path.GetFileName(FullPath); }
}
}
When a new tab is focused, get the document for the active tab and set the forms title from the FullPath of the document.
private void tabControl1_TabIndexChanged(object sender, EventArgs e)
{
Document activeDoc = GetDocumentFromActiveTab();
// Update win title with full path of active doc.
this.Text = (activeDoc.FullPath ?? "Unsaved document") + " MyApp" + version;
}
EDIT:
The key here is of course the method GetDocumentFromActiveTab() which isn't shown. You need to implement the data structures that manage your documents, and connects them to tabs. I did not include that in the answer, you need to try yourself. One idea is to make a type representing the entire application state including all tabs and documents.
public class Workspace
{
private Dictionary<SomeTypeOfView, Document> documentsOpenInViews;
// Methods to register a document to a tab, get document for a tab
// remove tab+document when tab is closed etc.
}

// not sure if this is what you want
say your filename with path is
string strFFL = #"C:\path\filename.format";
Console.WriteLine(System.IO.Path.GetFileName(strFFL)); //->filename.format
Console.WriteLine(System.IO.Path.GetDirectoryName(strFFL)); //-> C:\path
http://msdn.microsoft.com/en-us/library/system.io.path.getfilename(v=vs.110).aspx
http://msdn.microsoft.com/en-us/library/system.io.path.getdirectoryname(v=vs.110).aspx

I think this is actually backwards. I think you want to keep a full path to the file and be able to display the filename only on the tab. So I think you want Path.GetDirectory name.
From: http://msdn.microsoft.com/en-us/library/system.io.path.getdirectoryname(v=vs.110).aspx
string filePath = #"C:\MyDir\MySubDir\myfile.ext";
string directoryName;
int i = 0;
while (filePath != null)
{
directoryName = Path.GetDirectoryName(filePath);
Console.WriteLine("GetDirectoryName('{0}') returns '{1}'",
filePath, directoryName);
filePath = directoryName;
if (i == 1)
{
filePath = directoryName + #"\"; // this will preserve the previous path
}
i++;
}
/*
This code produces the following output:
GetDirectoryName('C:\MyDir\MySubDir\myfile.ext') returns 'C:\MyDir\MySubDir'
GetDirectoryName('C:\MyDir\MySubDir') returns 'C:\MyDir'
GetDirectoryName('C:\MyDir\') returns 'C:\MyDir'
GetDirectoryName('C:\MyDir') returns 'C:\'
GetDirectoryName('C:\') returns ''

Save image to folder and image path to database

I am making an application called Profiler to store some people's profiles, and will use a database to store the profile photo's path.
This is my FindPhoto button (to upload the profile photo):
private void btnFindPhoto_Click(object sender, EventArgs e)
{
ofdFindPhoto.Title = "Select a Photo ";
ofdFindPhoto.InitialDirectory = #"D:\Desktop";
ofdFindPhoto.FileName = "";
ofdFindPhoto.Filter = "JPEG Image|*.jpg|GIF Image|*.gif|PNG Image|*.png|BMP Image|*.bmp";
ofdFindPhoto.Multiselect = false;
if (ofdFindPhoto.ShowDialog() != DialogResult.OK) { return; }
// Show the recently uploaded photo on profile
picProfilePhoto.ImageLocation = ofdFindPhoto.FileName;
}
When the user clicks the button to save the profile, I get the txtName.Text, txtPhone.Text, txtDescription.Text and photo path to save to the database. I want to use something like this to save the photo path:
string photoPath = Application.StartupPath + #"\Photos\" + txtName.Text +
Path.GetExtension(ofdFindPhoto.FileName);
This should generate some path like:
Drive:\InstalledPath\Profiler\Username.jpg (or whatever extension)
In short, I need to place a folder inside the application's root, but this folder should be created on install or first run (preferably that I can use on debug, too).

if(!Directory.Exists(Application.StartupPath + #"\Photos"))
Directory.CreateDirectory(Application.StartupPath + #"\Photos");

try this in program.cs.It checks for folder when the application in opened
if (!Directory.Exists(AppDomain.CurrentDomain.BaseDirectory + "Profiles"))
{
Directory.CreateDirectory(AppDomain.CurrentDomain.BaseDirectory + "Profiles");
}
Application.Run(new form1());

A problem with Relative Path Resolution when setting an Image Source

I have built a small WPF application that allows users to upload documents and then select one to display.
The following is the code for the file copy.
public static void MoveFile( string directory, string subdirectory)
{
var open = new OpenFileDialog {Multiselect = false, Filter = "AllFiles|*.*"};
var newLocation = CreateNewDirectory( directory, subdirectory, open.FileName);
if ((bool) open.ShowDialog())
CopyFile(open.FileName, newLocation);
else
"You must select a file to upload".Show();
}
private static void CopyFile( string oldPath, string newPath)
{
if(!File.Exists(newPath))
File.Copy(oldPath, newPath);
else
string.Format("The file {0} already exists in the current directory.", Path.GetFileName(newPath)).Show();
}
The file is copied without incident. However, when the user tries to select a file they just copied to display, A file not found exception. After debugging, I've found that the UriSource for the dynamic image is resolving the relative path 'Files{selected file}' to the directory that was just browsed by the file select in the above code instead of the Application directory as it seems like it should.
This problem only occurs when a newly copied file is selected. If you restart the application and select the new file it works fine.
Here's the code that dynamically sets the Image source:
//Cover = XAML Image
Cover.Source(string.Format(#"Files\{0}\{1}", item.ItemID, item.CoverImage), "carton.ico");
...
public static void Source( this Image image, string filePath, string alternateFilePath)
{
try
{image.Source = GetSource(filePath);}
catch(Exception)
{image.Source = GetSource(alternateFilePath);}
}
private static BitmapImage GetSource(string filePath)
{
var source = new BitmapImage();
source.BeginInit();
source.UriSource = new Uri( filePath, UriKind.Relative);
//Without this option, the image never finishes loading if you change the source dynamically.
source.CacheOption = BitmapCacheOption.OnLoad;
source.EndInit();
return source;
}
I'm stumped. Any thought's would be appreciated.

Although I don't have a direct answer, you should use caution for such allowing people to upload files. I was at a seminar where they had good vs bad hackers to simulate real life exploits. One was such that files were allowed to be uploaded. They uploaded malicious asp.net files and called the files directly as they new where the images were ultimately presented to the users, and were able to eventually take over a system. You may want to verify somehow what TYPES of files are being allowed and maybe have stored in a non-exeucting directory of your web server.

It turns out I was missing an option in the constructor of my openfiledialogue. The dialogue was changing the current directory which was causing the relative paths to resolve incorrectly.
If you replace the open file with the following:
var open = new OpenFileDialog{ Multiselect = true, Filter = "AllFiles|*.*", RestoreDirectory = true};
The issue is resolved.
