The RichTextBox in C# is a text editing control that can be used to display and edit content in rich text format. Here are some common usage scenarios:<\/p>\n

    \n
  1. The text in the richTextBox has been set to “Hello, World!”.<\/li>\n
  2. Set the font and size:
    \nrichTextBox.Font = new Font(“Arial”, 12); \/\/ Set the font to Arial and font size to 12.<\/li>\n
  3. Set text style:
    \nrichTextBox.SelectionFont = new Font(richTextBox.Font, FontStyle.Bold); \/\/ Make selected text bold
    \nrichTextBox.SelectionColor = Color.Red; \/\/ Make selected text red<\/li>\n
  4. Add image:
    \nImage image = Image.FromFile(“image.jpg”);
    \nClipboard.SetImage(image);
    \nrichTextBox.Paste(); \/\/ Paste the image from the clipboard into the RichTextBox<\/li>\n
  5. Search and replace text:
    \nint index = richTextBox.Find(“World”); \/\/ Search for “World” in the text and return the index of the first match
    \nif (index >= 0)
    \n{
    \nrichTextBox.Select(index, “World”.Length); \/\/ Select the matching text
    \nrichTextBox.SelectedText = “Universe”; \/\/ Replace the selected text with “Universe”
    \n}<\/li>\n
  6. Save and load text:
    \nrichTextBox.SaveFile(“document.rtf”); \/\/ Save text to an RTF file
    \nrichTextBox.LoadFile(“document.rtf”); \/\/ Load text from an RTF file<\/li>\n<\/ol>\n
