Returns the index of the specified tree node in the collection.

 virtual int System.Collections.IList.IndexOf(System::Object ^ node) = System::Collections::IList::IndexOf;

int IList.IndexOf (object? node);

abstract member System.Collections.IList.IndexOf : obj -> int
override this.System.Collections.IList.IndexOf : obj -> int

Function IndexOf (node As Object) As Integer Implements IList.IndexOf

Parameters

node

Object

The TreeNode to locate in the collection.

Returns

Int32

The zero-based index of the item found in the tree node collection; otherwise, -1.

Remarks

If node is not a TreeNode, the IList.IndexOf method returns -1. Therefore, you cannot pass in a string to find the node that has the value of the string as its Text property.
