With a KeyUp event in txtInput (text box), I want to see if it finds html commands and highlight them with a blue color. Right now, it's highlighting everything in the textbox if it finds a html tag. How can I make sure it only sets the color of one word

private void txtInput_KeyUp(object sender, KeyEventArgs e){
string code = "<html>"; if (txtInput.Find(code) != -1){
txtInput.ForeColor = Color.Blue;
// txtInput.SelectedText.ForeColor =
Color.Blue; // wrong, but an ideal approach}
else{
}
}
How do I change the forground color of selected text?

Here's an update of my code: I'm getting a ton of repeated letters in the textbox, though. What do you think I can improve on here My resource is from this site: http://www.c-sharpcorner.com/Code/2003/June/SyntaxHighlightInRichTextBoxP1.asp
private void txtInput_KeyUp(object sender, KeyEventArgs e){
char[] t = { '(', '[', ' ', '\t', '{', '}', '(', ')', ':', ';', ']' }; String[] tokens = txtInput.Text.Split(t); foreach (string token in tokens){
txtInput.SelectionColor =
Color.Black;txtInput.SelectionFont =
new Font("Courier New", 10, FontStyle.Regular); // Check whether the token is a keyword. String[] keywords = {"public", "void", "using", "static", "class"}; for (int i = 0; i < keywords.Length; i++){
if (keywords{
// Apply alternative colortxtInput.SelectionColor =
Color.Blue;txtInput.SelectionFont =
new Font("Courier New", 10, FontStyle.Bold); break;}
}
txtInput.SelectedText = token;
//txtInput.SelectedText = "\n";}
}
