How to convert list of key-value pairs to list of string (key,value)

Question

I have a list of key-value pairs.

var y = this.Request.Cookies.ToList();

which would have multiple Key="Key",Value="value" pairs.

This has to be converted to a List of string => "key","Value" pairs.

Any suggestions?

Work with .Select() from System.Linq to convert Key-Value pair to string.

using System.Linq;

Dictionary<string, string> dict = new Dictionary<string, string>
{
    { "Key1", "Value1" },
    { "Key2", "Value2" },
    { "Key3", "Value3" }
};
        
List<string> result = dict
    .Select(x => $"{x.Key},{x.Value}")
    .ToList();
