C# | Dictionary.Values Property

Introduction

The Values property of the Dictionary<TKey, TValue> class in C# represents a collection of all the values of a dictionary. The dictionary is a key-value store where each value is associated with a unique key. The Values property provides a way to access all the values of the dictionary without the keys.

The Values property is of type ValueCollection<TKey, TValue> which is a collection of TValue objects. This collection implements the ICollection<T> and IEnumerable<T> interfaces to provide methods for adding, removing, and iterating through the values.

Syntax

The syntax for accessing the Values property is as follows:

Dictionary<TKey, TValue> dict = new Dictionary<TKey, TValue>();
ICollection<TValue> values = dict.Values;

Here, dict is the dictionary instance and values is the collection of values.

Usage

The Values property can be used in a variety of scenarios. The following are some common use cases:

1. Iterate through all the values of a dictionary

Dictionary<string, int> dict = new Dictionary<string, int>();
dict.Add("one", 1);
dict.Add("two", 2);
dict.Add("three", 3);

foreach(int value in dict.Values)
{
    Console.WriteLine(value);
}

Output:

1
2
3

2. Convert the values to an array

Dictionary<string, string> dict = new Dictionary<string, string>();
dict.Add("one", "1");
dict.Add("two", "2");
dict.Add("three", "3");

string[] values = dict.Values.ToArray();

3. Pass the values to a method or API

Dictionary<string, string> dict = new Dictionary<string, string>();
dict.Add("one", "1");
dict.Add("two", "2");
dict.Add("three", "3");

API.UploadData(dict.Values);

Conclusion

The Values property of the Dictionary<TKey, TValue> class in C# provides a convenient way to access all the values of a dictionary. It can be used to iterate through the values, convert them to an array, or pass them to a method or API.
