Path.IsPathRooted Method

Gets a value indicating whether the specified path string contains absolute or relative path information.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

public static bool IsPathRooted(
	string path
)

Parameters

path
Type: System.String

The path to test.

Return Value

Type: System.Boolean
true if path contains an absolute path; otherwise, false.

ExceptionCondition
ArgumentException

path contains one or more of the invalid characters defined in GetInvalidPathChars.

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.

string fileName = @"C:\mydir\myfile.ext";
string UncPath = @"\\myPc\mydir\myfile";
string relativePath = @"mydir\sudir\";
bool result;

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: 
// 
// IsPathRooted('C:\mydir\myfile.ext') returns True 
// IsPathRooted('\\myPc\mydir\myfile') returns True 
// IsPathRooted('mydir\sudir\') returns False
