You need to display the modified text after comparing two lines

Question

I have two lines:

1 line = "stackoverflow"

2 string = "stackoverflow is good"

I want to show: "stackoverflow is good ".

"good" should be highlighted with a background color ..

how is this possible to do with c #?

Answer 1

First format all the text in the selected color, then find "stackoverflow" and format it in the normal format. This way, you don’t have to bother with the problem of finding something, but formatting something else.

For technical details, I need to know what control you use to display text (text box, Rtf, Html).

 static void Main(string[] args) { string strComplete = "stackoverflow is good, I mean, stackoverflow is really good"; string strSearch = "stackoverflow"; Console.WriteLine(FormatString(strComplete, strSearch)); Console.ReadKey(); } private static string FormatString(string strComplete, string strSearch) { string strSpannedSearch = string.Format("{0}{1}{2}", "", strSearch, ""); return strComplete.Replace(strSearch, strSpannedSearch); }
static void Main(string[] args) { string strComplete = "stackoverflow is good, I mean, stackoverflow is really good"; string strSearch = "stackoverflow"; Console.WriteLine(FormatString(strComplete, strSearch)); Console.ReadKey(); } private static string FormatString(string strComplete, string strSearch) { string strSpannedSearch = string.Format("{0}{1}{2}", "", strSearch, ""); return strComplete.Replace(strSearch, strSpannedSearch); }

You can try something in these lines

 string s1 = "Hello"; string s2 = "Hello world"; s2= s2.Replace(s1, ""); Bitmap bmap = new Bitmap(150, 25); Graphics graphic = Graphics.FromImage(bmap); graphic.DrawString(s1, new Font(FontFamily.GenericSerif, 8), new SolidBrush(Color.White), new PointF()); graphic.DrawString(s2, new Font(FontFamily.GenericSerif, 8), new SolidBrush(Color.Yellow), new PointF()); bmap.Save("myimage.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
