public sealed class Path : IComparable<Path>, IEquatable<Path>, IStorable

Paths are used to identify twigs in data trees. Paths are ordered, immutable collections of non-negative integers.

## Constructors

- [Path](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.path/ctor.md): (3 overloads) Create a new instance of TreePath based on a collection of indices.

## Fields

- [Zero](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.path/zero.md): (static) Gets the single element path with a value of zero: {0}
- [ZeroZero](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.path/zerozero.md): (static) Gets the double element path with two zeroes: {0, 0}

## Properties

- [LastElement](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.path/lastelement.md): Gets the last element in the path.

- [Increment](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.path/increment.md): (2 overloads) Increment this path by one. The rightmost non-zero value is incremented, or, if all values are zero, the rightmost value is set to 1.
- [IndexOf](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.path/indexof.md): (2 overloads) Finds the first occurance of a string of integers within the path.
- [MakeUnique](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.path/makeunique.md): Make sure the current path is unique amongst a collection of paths.
- [Offset](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.path/offset.md): Offset an element in this path
- [PadLeft](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.path/padleft.md): Pad a pad on the leading edge until it reaches a certain length.

- [ParsePattern](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.path/parsepattern.md): (static) Try and parse a string that may represent some sort of path notation, yielding a view of each element and of the item. Nothing is said about what the elements contain, so this reads the wildcards and expressions of path mapping as readily as it reads the whole numbers of a data path.
