Round #746

Iterate over a Dictionary<string, int> and print each key-value pair.

```csharp using System; using System.Collections.Generic; class Program { static void Main() { // Create a dictionary var myDict = new Dictionary<string, int> { {"a", 1}, {"b", 2}, {"c", 3}, {"d", 4}, {"e", 5} }; // Iterate over the dictionary and print each key-value pair foreach (var pair in myDict) { Console.WriteLine($"Key: {pair.Key}, Value: {pair.Value}"); } } } ```

```csharp using System; using System.Collections.Generic; public class Program { public static void PrintDictionary(Dictionary<string, int> dictionary) { try { foreach (var pair in dictionary) { Console.WriteLine($"Key: {pair.Key}, Value: {pair.Value}"); } } catch (Exception ex) { Console.WriteLine($"An error occurred: {ex.Message}"); } } public static void Main(string[] args) { var dictionary = new Dictionary<string, int> { {"Apple", 1}, {"Banana", 2}, {"Cherry", 3} }; PrintDictionary(dictionary); } } ``` This C# code defines a method `PrintDictionary` that iterates over a `Dictionary<string, int>` using a `foreach` loop. Inside the loop, it prints each key-value pair to the console. The code also includes basic error handling to catch any exceptions that may occur during execution. In the `Main` method, an example dictionary is created and passed to the `PrintDictionary` method to demonstrate its usage. The output will be: ``` Key: Apple, Value: 1 Key: Banana, Value: 2 Key: Cherry, Value: 3 ```
