RichTextBox Number of Lines 1

[javijerome]

Hi, name is jerome. i'm a beginner is Visual C# 2008. i have a richtextbox in my form and i want to get the number of lines that was used when the user typed some sentences in the richtextbox area. what codes or RTB property should be placed in the Number_of_lines button class, in order that when the button is click, it show the number of lines through a message box.

MessageBox.Show(string.Format("Number of lines: {0}", this.RTB.Lines.LongLength.ToString()));

I think this.RTB.Lines.LongLength is the number of lines separated by newline but not by word wrap.

thanks for the respond TipGiver. i forgot to say that i also want to get the value as an integer. so that the lines will be placed in a string array. and the number of lines will be used as an index for the string array. how do i get the number of lines in integer value?

Yes, the .Lines[] array has the lines seperated by newline. Just checked it.

To get the number as Integer (=32bit wide) use instead the .Length property.
Note that the 'RTB.Lines' is an array itself. Maybe you can use it too. The following will show the second line (what is there on the 2nd line). The array as usual is zero based so 1st line is at index 0, 2nd line is at index 1 .... N-th line is at index (N-1)

MessageBox.Show(this.RTB.Lines[1].ToString());
