I am trying to save an xml file to C:\Program file\MyApplicationFolder\my.xml, but I am receving an access denied error.

write.WriteStartElement("Setting");

C:\Program Files is a restricted folder. Only administrators can modify the contents of this folder.
Use this code to generate a path:
FileName = Path.Combine( _
Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData), _
"MyApplicationFolder\My.xml" _
)
This saves to a folder the user has access to:
C:\Users\<username>\AppData\Roaming\MyApplicationFolder\My.xml
Try saving to the per-user Application Data directory instead.

How to walk a directory application project ASP.NET MVC 3 ?
For example: I must find one file in derectory MyApp.WebUI/controls
You could use the Directory.EnumerateFiles method. Or if you already know the name of the file you could directly access this file. In order to calculate the absolute path to this directory/file you should use the Server.MapPath method:
var location = Server.MapPath("~/MyApp.WebUI/controls");
var files = Directory.EnumerateFiles(location);

I'm creating a program in C# WPF that allows the user to manually input a directory in a textbox so that the program will retrieve and list the files in the specified directory into another textbox.
My problem is that I don't know how to assign the value from a textbox to the directory path.
I'm able to specify the directory manually in the code however I'm not sure how to assign the directory path from a textbox...
Any ideas?
My code when a button is clicked is as follows:
// Makes a reference to a directory.
DirectoryInfo di = new DirectoryInfo(#"C:\");
DirectoryInfo di = new DirectoryInfo(textbox.Text);
That should work.

After Creating an Excel file using C#, I'm trying to open the file, and get the following exception:
"excel cannot open the file because the file format or file extension is not valid. verify that the file has not been corrupted and that the file extention matches the format of the file."
Any suggestions?
Without any code and by reading the error, I have the suspect that you're specifing the wrong extension in the path when you save the file, which is a common mistake:
string path = "C:\\excelfile.xls"; //or xlsx as said #JMK

The operating system will not let you delete a file in use by another process.
Use this tool to find out what process is accessing the files you are trying to delete:

I'm trying to access a file inside my project.
So I would create a new folder called Files and inside that folder contains various HTML files.
Is there anyway that I can access those files by going to "Program/Files/file.html" or similar.
Do you mean something like this?
using System.IO;
...
string folderPath = AppDomain.CurrentDomain.BaseDirectory; // or whatever folder you want to load..
foreach (string file in Directory.EnumerateFiles(folderPath, "*.html"))
{
string contents = File.ReadAllText(file);
}
