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.
