从设置位置的文件中打开RichTextBox

Question

I need to have a richtextbox (rtbUsers) load up a .txt or .rtf (Whatever is easiest) on either form loadup or when a button is pressed (btnLoad) from: C:\\ProgramData\\Project\\test.txt

The only code I have found is for the openfile dialogue, but I need it from a set location. So I am asking if anyone could please give me the code that I need. Thanks :)

Answer 1

Just call the LoadFile method:

richTextBox1.LoadFile("mypathandfile.rtf")

For a text file, there is an overload you can use:

richTextBox1.LoadFile("mypathandfile.txt", RichTextBoxStreamType.PlainText)
