rtf change font size

Question

I am trying to perform edit functions in a RichTextBox on a C# (Windows Forms) application. I would like to be able to select any number of text characters in the script then change targeted font characteristics.
The trouble I have is that each characters font properties may be set to different font. In this case the textbox ignores the event that I request.

How can I solve my problem?

I haven't found a solution to that problem either, so I had to scan the selection one character at a time to find chunks with all the same font properties and change the size of each of those chunks. So I'm hoping that better answers emerge here! — Mr Lister, Nov 30 '12 at 10:16

Take a look at this: Changing font for richtextbox without losing formatting

I think it's the same issue. LarsTech's solution is working perfectly for me.

I have a code to change the size:

RichTextBox1.Font.Size == new System.Drawing.Font(RichTextBox1.Font.Name, yoursize)

And if you want to change only the selected text size:

RichTextBox1.SelectionFont.Size == new System.Drawing.Font(RichTextBox1.SelectionFont.Name, yoursize)

Hope it will help.

Control Size is not equatable to a Font. – LarsTech May 10 '13 at 14:00
Sorry, I meant RichTextBox1.Font.Size == new System.Drawing.Font(RichTextBox1.Font.Name, yoursize) – Benjli May 10 '13 at 15:06
