The question is not tagged with the UI.
In Windows Forms, the TextBox control does not support assigning different BackColor for different lines.
For this purpose the RichTextBox control explained here
http://msdn.microsoft.com/en-us/library/3tdc88y7.aspx[^]
can be used.
However, to highlight a contiguous block of Text the SelectionStart and SelectionLenth properties of TextBox can be used as explained here
