Getting File Path in ASP.NET MVC [duplicate]

I am trying to construct a file path in order to read an XSLT file, like so:
string path = "../_xslt/example.xslt";
StreamReader reader = new StreamReader(path);
...where I am in a controller (/Controllers/ExampleController.cs), and the '/_xslt/' folder is at the same level as '/Controllers'
However, the error I am getting is:
(System.IO.DirectoryNotFoundException)
Could not find a part of the path 'c:\windows\system32\_xslt\example.xslt'.
Am I going about this the wrong way?
Thanks for any help!

You can use the HttpServerUtility.MapPath method to map any relative paths for you, in your controller this is easily accessible via the ControllerContext:
string path = ControllerContext.HttpContext.Server.MapPath("~/_xslt/example.xslt");
...

string TestX()
{
string path = AppDomain.CurrentDomain.BaseDirectory; // You get main rott
string dirc = ""; // just var for use
string[] pathes = Directory.GetDirectories(path); // get collection
foreach (string str in pathes)
{
if (str.Contains("NameYRDirectory")) // paste yr directory
{
dirc = str;
}
}
return dirc; // after use Method and modify as you like
}

If controller is present at directory root
String path = ControllerContext.HttpContext.Server.MapPath(#"~/_xslt/example.xslt");
Else
String path = ControllerContext.HttpContext.Server.MapPath(#"../_xslt/example.xslt");

How to go one step above in a folder path by using AppDomain.CurrentDomain.BaseDirectory in c#

I am using AppDomain.CurrentDomain.BaseDirectory and I want to go one step backwards but couldn't figure out how? Below is the example,
CODE :
string path = AppDomain.CurrentDomain.BaseDirectory;
RESULT :
"C:\\Mainline Code\\IxExpress\\.NET Applications\\IXTextIndexBuilder\\IXTextIndexBuilder\\bin\\Debug\\"
EXPECTED RESULT:
"C:\\Mainline Code\\IxExpress\\.NET Applications\\IXTextIndexBuilder\\IXTextIndexBuilder\\bin"

You can use something like the following to get the parent of a given directory:
string dirName = AppDomain.CurrentDomain.BaseDirectory; // Starting Dir
FileInfo fileInfo = new FileInfo(dirName);
DirectoryInfo parentDir = fileInfo.Directory.Parent;
string parentDirName = parentDir.FullName; // Parent of Starting Dir

Use following snippet:
string path = (new FileInfo(AppDomain.CurrentDomain.BaseDirectory)).Directory.Parent.FullName;

Directory.GetParent(AppDomain.CurrentDomain.BaseDirectory).Parent.FullName

Need to get application folder

I need to get my application directory and add a file name to that path. So I used it this way.
String kofaxTextFilePath = Path.GetDirectoryName(Assembly.GetAssembly(typeof(File)).CodeBase) + "\\KofaxBatchHistory.txt"
So it will give a path like this.
“file:\\C:\\Documents and Settings\\MyApplication\\ KofaxBatchHistory.txt”
But I need to get only
C:\\Documents and Settings\\MyApplication\\ KofaxBatchHistory.txt
With out doing any thing to this string is there any method to get it directly?

string myDir = System.Reflection.Assembly.GetExecutingAssembly().Location;
myDir = System.IO.Path.GetDirectoryName(myDir);
String kofaxTextFilePath = System.IO.Path.Combine(myDir, "KofaxBatchHistory.txt");

Try Assembly.Location.
Assembly.GetAssembly(typeof(File)).Location
Or (better yet):
typeof(File).Assembly.Location

Automatically create directories from long paths

I have a collection of files with fully qualified paths (root/test/thing1/thing2/file.txt). I want to foreach over this collection and drop the file into the location defined in the path, however, if certain directories don't exist, I want them to great created automatically. My program has a default "drop location", such as z:/. The "drop location" starts off empty, so in my example above, the first item should automatically create the directories needed to create z:/root/test/thing1/thing2/file.txt. How can I do this?

foreach (var relativePath in files.Keys)
{
var fullPath = Path.Combine(defaultLocation, relativePath);
var directory = Path.GetDirectoryName(fullPath);
Directory.CreateDirectory(directory);
saveFile(fullPath, files[relativePath]);
}
where files is IDictionary<string, object>.

string somepath = #"z:/root/test/thing1/thing2/file.txt";
System.IO.Directory.CreateDirectory(System.IO.Path.GetDirectoryName( ( somepath ) );

Directory.CreateDirectory("/root/...")
Creates all directories and subdirectories in the specified path

Check IO namespace (Directory, Path), I think they'll help you
using System.IO
Then check it..
string fileName =#"d:/root/test/thing1/thing2/file.txt";
string directory = Path.GetDirectoryName(fileName);
if (!Directory.Exists(directory))
Directory.CreateDirectory(directory);

string filename = "c:\\temp\\wibble\\wobble\\file.txt";
string dir = Path.GetDirectoryName(filename);
if (!Directory.Exists(dir))
{
Directory.CreateDirectory(dir);
}
File.Create(filename);
with suitable exception handling, of course.

I've found setting the "default location" at the start of execution to be helpful and reduce a bit of redundant code (e.g., Path.Combine(defaultLocation, relativePath)).
Example:
var defaultLocation = "z:/";
Directory.SetCurrentDirectory(defaultLocation);
Directory.SetCurrentDirectory(AppContext.BaseDirectory);

How can get the current virtual path without file name?

Request.Path will get the current Path name with file name such as:
C:/......./Personal/Items.aspx
How can I get the only Path name such as:
C:/......./Personal

You can use Path.GetDirectoryName to get the directory part of a path.
var path = System.IO.Path.GetDirectoryName(#"C:\Personal\Items.aspx");
// path is #"C:\Personal"

This will return the virtual path:
Page.TemplateSourceDirectory
See the below answers for the physical path.

Use the GetParent() method on Directory.
DirectoryInfo parent = Directory.GetParent(requestPath);

you can get Directory Path from System.IO.FileInfo
var fInfo = new System.IO.FileInfo(path);
var result = fInfo.DirectoryName;
