MoreEnumerableTraverseDepthFirstT Method

Traverses a tree in a depth-first fashion, starting at a root node and using a user-defined function to get the children at each node of the tree.

Namespace:  MoreLinq
Assembly:  MoreLinq (in MoreLinq.dll) Version: 2.4.0
Syntax
Copy
public static IEnumerable<T> TraverseDepthFirst<T>(
	T root,
	Func<T, IEnumerable<T>> childrenSelector
)

Parameters

root
Type: T
The root of the tree to traverse
childrenSelector
Type: SystemFuncT, IEnumerableT
The function that produces the children of each element

Type Parameters

T
The tree node type

Return Value

Type: IEnumerableT
A sequence containing the traversed values
Remarks
This function defers traversal until needed and streams the results. The tree is not checked for loops. If the resulting sequence needs to be finite then it is the responsibility of childrenSelector to ensure that loops are not produced.
