Path.IsPathRooted Method
Gets a value indicating whether the specified path string contains a root.
Namespace: System.IO
Assembly: mscorlib (in mscorlib.dll)
Parameters
- path
- Type: System.String
The path to test.
| Exception | Condition |
|---|---|
| ArgumentException | path contains one or more of the invalid characters defined in GetInvalidPathChars. |
The IsPathRooted method returns true if the first character is a directory separator character such as "\", or if the path starts with a drive letter and colon (:). For example, it returns true for path strings such as "\\MyDir\\MyFile.txt", "C:\\MyDir", or "C:MyDir". It returns false for path strings such as "MyDir".
This method does not verify that the path or file name exists.

The following code example demonstrates how the IsPathRooted method can be used to test three strings.
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
