QuickGraph 3.6: Generic Graph Data Structures and Algorithms for .NET.
QuickGraph provides generic directed/undirected graph datastructures and algorithms for .NET. QuickGraph comes with algorithms such as depth first seach, breath first search, A* search, shortest path, k-shortest path, maximum flow, minimum spanning tree, least common ancestors, etc... QuickGraph supports MSAGL, GLEE, and Graphviz to render the graphs, serialization to GraphML, etc...
NuGet Instructions
  • PM> Install-Package QuickGraph
A simple example
This example takes a DataSet, builds the graph of table and constraints from the schema and computes the table topological sort (useful to figure order to populate a database):
DataSet ds = new MyDataSet(); // your dataset
var graph = ds.ToGraph();  // wraps the dataset into a DataSetGraph
foreach(DataTable table in graph.TopologicalSort()) // applies a topological sort to the dataset graph
    Console.WriteLine(table.TableName); // in which order should we delete the tables?
  • QuickGraph 3.6. Portable Class Library support.
  • QuickGraph 3.3.51106.0 available on nuget, no more support for .NET 2.0.
  • QuickGraph 3.3 (updated) added Code Contracts reference assemblies
  • QuickGraph 3.3 adds new graph data structures based on delegates
  • QuickGraph 3.2 (bis) supporting Silveright
  • QuickGraph 3.2 started using Code Contracts.
  • QuickGraph 3.1 brings a Fibonacci Heap and support for 2.0 is back.
  • QuickGraph 3.0 takes advantage of extension methods to simplify tasks.
  • QuickGraph 2.0 introduced support for generic graph data structures
  • The original QuickGraph for .net 1.0 was posted on CodeProject in 8 Dec 2003. It was time to do a refresh and make the graph generic.

The design of QuickGraph is inspired from the Boost Graph Library.
