Definition

Overloads

GetFullPath(String) GetFullPath(String) GetFullPath(String) GetFullPath(String)

Returns the absolute path for the specified path string.

public:
 static System::String ^ GetFullPath(System::String ^ path, System::String ^ basePath);
public static string GetFullPath (string path, string basePath);
static member GetFullPath : string * string -> string
Public Shared Function GetFullPath (path As String, basePath As String) As String

Parameters

Returns

GetFullPath(String) GetFullPath(String) GetFullPath(String) GetFullPath(String)

Returns the absolute path for the specified path string.

public:
 static System::String ^ GetFullPath(System::String ^ path);
public static string GetFullPath (string path);
static member GetFullPath : string -> string
Public Shared Function GetFullPath (path As String) As String

Parameters

path
String String String String

The file or directory for which to obtain absolute path information.

Returns

The fully qualified location of path, such as "C:\MyFile.txt".

Exceptions

path is a zero-length string, contains only white space, or contains one or more of the invalid characters defined in GetInvalidPathChars().

-or-

The system could not retrieve the absolute path.

The caller does not have the required permissions.

path contains a colon (":") that is not part of a volume identifier (for example, "c:\").

The specified path, file name, or both exceed the system-defined maximum length.

Examples

The following example demonstrates the GetFullPath method on a Windows-based desktop platform.

String^ fileName = "myfile.ext";
String^ path = "\\mydir\\";
String^ fullPath;
fullPath = Path::GetFullPath( path );
Console::WriteLine( "GetFullPath('{0}') returns '{1}'", path, fullPath );
fullPath = Path::GetFullPath( fileName );
Console::WriteLine( "GetFullPath('{0}') returns '{1}'", fileName, fullPath );

// Output is based on your current directory, except
// in the last case, where it is based on the root drive
// GetFullPath('mydir') returns 'C:\temp\Demo\mydir'
// GetFullPath('myfile.ext') returns 'C:\temp\Demo\myfile.ext'
// GetFullPath('\mydir') returns 'C:\mydir'
string fileName = "myfile.ext";
string path1 = @"mydir";
string path2 = @"\mydir";
string fullPath;

fullPath = Path.GetFullPath(path1);
Console.WriteLine("GetFullPath('{0}') returns '{1}'", 
    path1, fullPath);

fullPath = Path.GetFullPath(fileName);
Console.WriteLine("GetFullPath('{0}') returns '{1}'", 
    fileName, fullPath);

fullPath = Path.GetFullPath(path2);
Console.WriteLine("GetFullPath('{0}') returns '{1}'", 
    path2, fullPath);

// Output is based on your current directory, except
// in the last case, where it is based on the root drive
// GetFullPath('mydir') returns 'C:\temp\Demo\mydir'
// GetFullPath('myfile.ext') returns 'C:\temp\Demo\myfile.ext'
// GetFullPath('\mydir') returns 'C:\mydir'
Dim fileName As string = "myfile.ext"
Dim path1 As string = "mydir"
Dim path2 As string = "\mydir"
Dim fullPath As string

fullPath = Path.GetFullPath(path1)
Console.WriteLine("GetFullPath('{0}') returns '{1}'", _
    path1, fullPath)

fullPath = Path.GetFullPath(fileName)
Console.WriteLine("GetFullPath('{0}') returns '{1}'", _
    fileName, fullPath)

fullPath = Path.GetFullPath(path2)
Console.WriteLine("GetFullPath('{0}') returns '{1}'", _
    path2, fullPath)

' Output is based on your current directory, except
' in the last case, where it is based on the root drive
' GetFullPath('mydir') returns 'C:\temp\Demo\mydir'
' GetFullPath('myfile.ext') returns 'C:\temp\Demo\myfile.ext'
' GetFullPath('\mydir') returns 'C:\mydir'

Remarks

The absolute path includes all information required to locate a file or directory on a system.

The file or directory specified by path is not required to exist. For example, if c:\temp\newdir is the current directory, calling GetFullPath on a file name such as test.txt returns c:\temp\newdir\test.txt. The file need not exist.

However, if path does exist, the caller must have permission to obtain path information for path. Note that unlike most members of the Path class, this method accesses the file system.

This method uses current directory and current volume information to fully qualify path. If you specify a file name only in path, GetFullPath returns the fully qualified path of the current directory.

If you pass in a short file name, it is expanded to a long file name.

If a path contains no significant characters it is invalid unless it contains one or more "." characters followed by any number of spaces, then it will be parsed as either "." or "..".

.NET Core 1.1 and later versions and .NET Framework 4.6.2 and later versions also support paths that include device names, such as "\?\C:".
