Converting the Dictionary Keys to String List

In this code snippet you will learn to Convert the Dictionary keys to string list.

We cannot covert the Dictionary keys to List<string> directly. Because the return type of the Key is KeyCollection. Here is the code to convert the keys to string list.

Method 1

Dictionary<string, string> dictionary = new Dictionary<string, string>();
dictionary.Add("One", "1");
dictionary.Add("Two", "2");
List<string> keys=new List<string>(dictionary.Keys);

Method 2

Dictionary<string, string> dictionary = new Dictionary<string, string>();
dictionary.Add("One", "1");
dictionary.Add("Two", "2");
var key = dictionary.Keys;
List<string> keys1= key.Cast<string>().ToList();
