What's the Standard Way to Iterate Through Dictionaries in C#?

The Preferred Way to Iterate Through C# Dictionaries

C# offers multiple ways to iterate through dictionaries. However, the most common and recommended approach uses a foreach loop for its clarity and efficiency.

The foreach loop directly accesses each key-value pair in the dictionary. The example below shows how this works: The loop assigns each KeyValuePair<string, string> to the entry variable. entry.Key provides access to the key, and entry.Value gives access to the corresponding value. This allows for easy manipulation of both key and value within the loop.

This method is considered standard because it's highly readable and uses the optimized foreach loop designed for efficient collection traversal. This improves code maintainability and collaboration.
