Exploring Dictionary Iteration in C#: Step-by-Step Guide

To iterate through a dictionary in C#, you can use a `foreach` loop or a `for` loop.

Here's an example of using a `foreach` loop to iterate through a dictionary:

Dictionary<string, int> dict = new Dictionary<string, int>(); dict.Add("apple", 3); dict.Add("banana", 2); dict.Add("cherry", 5); foreach (KeyValuePair<string, int> pair in dict) {     Console.WriteLine("{0}: {1}", pair.Key, pair.Value); }

In this example, we have a dictionary that maps strings to integers. We use a `foreach` loop to iterate over the key-value pairs in the dictionary and print each key-value pair to the console.

Alternatively, you can use a `for` loop to iterate through the keys or values of the dictionary:

Dictionary<string, int> dict = new Dictionary<string, int>();         dict.Add("apple", 3); dict.Add("banana", 2); dict.Add("cherry", 5);   for (int i = 0; i<dict.Count; i++) {     string key = dict.Keys.ElementAt(i);         int value = dict.Values.ElementAt(i);         Console.WriteLine("{0}: {1}", key, value); }

In this example, we use a `for` loop to iterate over the keys and values in the dictionary and print each key-value pair to the console. We use the `Keys` and `Values` properties of the dictionary to get the keys and values as `IEnumerable` collections, and then use the `ElementAt` method to get the key and value at each index.
