Remove text from string using string to find text?

If you wanted to get part of a user inputed responce, you would doing something along the lines of

string textToRemove = "set background ";
Console.WriteLine("Type 'set background ' then your color.");
string userInput = Console.ReadLine();
string answer = userInput.Replace(textToRemove, string.empty);
SetBackgroundColor(answer);

First what you want to do is set the text you don't care about/need

string textToRemove = "set background ";

Next you are going to tell the user what to input and get the input

Console.WriteLine("Type 'set background ' then your color.");
string userInput = Console.ReadLine();

We would then have to make a new string without the unnessary text

string answer = userInput.Replace(textToRemove, string.empty);

In this case we are using the input to set the background color. So we would write a function for changing the background color with a string argument for the color the user gave.

SetBackgroundColor(answer);

You could also use an If statment or an for/foreach statment to see if the user's text without the unneccasry text is in an array or list containing strings that are allowed to be used.
