Data Structures in C#
Data Structures&Algorithms is one of the basic courses in computer science and programming questions related to data structures such as linked lists, binary tress are focused a lot in Microsoft's SDE, SDE/T interviews (More than 50% of the coding questions in my interview were related to linked lists). Scott Mitchell of 4GuysFromRolla had authored series of articles about data structures in C# in MSDN. It might be helpful to ramp up data structures in C# or to learn from scratch.
Here are the links of all the articles:
Part 1: An Introduction to Data Structures
Part 2: The Queue, Stack, and Hashtable
Part 3: Binary Tress and BSTs
Part 4: Building a Better Binary Search Tree
Part 5: From Trees to Graphs
Part 6: Efficiently Representing Sets
