I have text. for example string text = "COMPUTER"
And I want to split it into characters, to keep every character as string.
If there were any delimiter I can use text.Split(delimiter).
But there is not any delimiter, I convert it to char array with
text.ToCharArray().toList().
And after that I get List<char>. But I need List<string>.
So How can I convert List<char> to List<string>.

Just iterate over the collection of characters, and convert each to a string:

var result = input.ToCharArray().Select(c => c.ToString()).ToList();

Or shorter (and more efficient, since we're not creating an extra array in between):

var result = input.Select(c => c.ToString()).ToList();

Try following

string text = "COMPUTER"
var listOfChars = text.Select(x=>new String(new char[]{x})).ToArray()

Use the fact that a string is internally already very close to an char[]

Approach without LINQ:

List<string> list = new List<string();
for(int i = 0; i < s.Length; i++)
    list.Add(s[i].ToString());

    string bla = "COMPUTER"; //Your String
    List<char> list = bla.ToCharArray().ToList(); //Your char list
    List<string> otherList = new List<string>(); //Your string list
    list.ForEach(c => otherList.Add(c.ToString())); //iterate through char-list convert every char to string and add it to your string list

Use this:

Key:

charList is your Character List

strList is your String List

Code:

List<string> strList = new List<string>();
foreach(char x in charList)
{
    strList.Add(x.ToString());
}
