The Dictionary is a collection. We can use the foreach loop to go through all the items and read them using they Key ad Value properties.

foreach (KeyValuePair<string, Int16> author in AuthorList)
{
     Console.WriteLine("Key: {0}, Value: {1}",author.Key, author.Value);
}

The following code snippet creates a new dictionary and reads all of its items and displays on the console.

public void CreateDictionary()
{
    // Create a dictionary with string key and Int16 value pair
    Dictionary<string, Int16> AuthorList = new Dictionary<string, Int16>();
    AuthorList.Add("Mahesh Chand", 35);
    AuthorList.Add("Mike Gold", 25);
    AuthorList.Add("Praveen Kumar", 29);
    AuthorList.Add("Raj Beniwal", 21);
    AuthorList.Add("Dinesh Beniwal", 84);
    // Read all data
    Console.WriteLine("Authors List");
    foreach (KeyValuePair<string, Int16> author in AuthorList)
    {
        Console.WriteLine("Key: {0}, Value: {1}",author.Key, author.Value);
    }
}
