String Replace in C# exact match word

Question

string original="Blue, Light Blue, Dark Blue";
string replace="Blue";
string replaceTo="Green";
string result=original.Replace(replace,replaceTo);
Console.WriteLine(result);

Output: Green, Light Green, Dark Green

But What I want: Green, Light Blue, Dark Blue

You are asking to replace "Blue" with "Green" but you want the result to have "Blue" instead of "Green"? Just do `Console.WriteLine(original)` then — Camilo Terevinto, Oct 06 '18 at 16:40
the op is saying he only wants to change the instance of blue without any modifiers. ie just change 'blue' but not 'light blue' or 'dark blue'. — Technivorous, Oct 06 '18 at 16:46

I would split original into a string[], then iterate over it and replace the exact match.

Code:

string[] lister = original.Split(',');

for (int i = 0; i < lister.Length; i++)
{
    if(lister[i] == "Blue")
    {
        lister[i] = "Green";
    }
}
