A tool to write a tree structure to the console standard output stream, with colors support and a lot of customization options.
To add ConsoleTree to your project, you can use the following NuGet Package Manager command:
Install-Package ConsoleTreeMore options are available on the ConsoleTree page of the NuGet Gallery website.
Implement the ITreeNode interface to obtain the node of a tree structure. Optionally override the ToString method to provide a custom text for the node. To write a tree structure to the console standard output stream, call the Tree.Write method specifying its root node as parameter.
class TreeNode : ITreeNode
{
public string Text { get; set; }
public List<TreeNode> Nodes { get; set; } = new List<TreeNode>();
public IEnumerable<ITreeNode> GetNodes()
{
return Nodes;
}
public override string ToString()
{
return Text;
}
}
var tree = new TreeNode
{
Text = "a",
Nodes = new List<TreeNode>
{
new TreeNode { Text = "b"},
new TreeNode { Text = "c"}
}
};
Tree.Write(tree, new DisplaySettings { IndentSize = 2 });
// Output:
//
// a
// ├──b
// └──cIf it is not possible or not desired to implement the ITreeNode interface, then use the Tree.Write<T> method overloads.
sealed class TreeNode
{
public string Text { get; set; }
public List<TreeNode> Nodes { get; set; } = new List<TreeNode>();
}
var tree = new TreeNode
{
Text = "a",
Nodes = new List<TreeNode>
{
new TreeNode { Text = "b"},
new TreeNode { Text = "c"}
}
};
Tree.Write(tree, (node, level) => Console.Write(node.Text), (node, level) => node.Nodes, new DisplaySettings { IndentSize = 2 });
// Output:
//
// a
// ├──b
// └──cSee the API reference and the ConsoleTree.Demo application to learn how to customize indentation, maximum depth, type of connectors and colors.
