Visual Basic (Declaration)
Public Shared Function IsPathRooted ( _
path As String _
) As Boolean
Dim path As String
Dim returnValue As Boolean
returnValue = Path.IsPathRooted(path)
public static bool IsPathRooted(
string path
)
public:
static bool IsPathRooted(
String^ path
)
public static function IsPathRooted(
path : String
) : boolean
Return Value
Type:
System..::.Boolean
true if path contains an absolute path; otherwise, false.
This method does not verify that the path or file name exists.
IsPathRooted returns true for path strings such as "\\MyDir\\MyFile.txt" and "C:\\MyDir". It returns false for path strings such as "MyDir".
IsPathRooted returns true if the first character is a directory separator character, such as "\", or the second character is a volume separator character, such as the second slash in "\\".

The following code example demonstrates a use of the IsPathRooted method.
Dim fileName As String = "C:\mydir\myfile.ext"
Dim UncPath As String = "\\myPc\mydir\myfile"
Dim relativePath As String = "mydir\sudir\"
Dim result As Boolean
result = Path.IsPathRooted(fileName)
Console.WriteLine("IsPathRooted('{0}') returns {1}", fileName, result)
result = Path.IsPathRooted(UncPath)
Console.WriteLine("IsPathRooted('{0}') returns {1}", UncPath, result)
result = Path.IsPathRooted(relativePath)
Console.WriteLine("IsPathRooted('{0}') returns {1}", relativePath, result)
' This code produces output similar to the following:
