Cannot assign to nullable double variable

Question

I have used DocX library to create a .docx document from text in my TextBoxs. I have a problem that I can't assign size of nullable variable to other variable (only can assign to value)

var infoFormatting = new Formatting();
infoFormatting.Size = txt_Info.Font.Size //txt_Info is a TextBox

How can I solve this problem? Thanks.

I have investigated and the `infoFormatting.Size` is `double?` and `Font.Size` is `single`. I don't see what could be the problem other than casting/converting source to `double`. — Dusan, May 24 '15 at 12:17

How about:

infoFormatting.Size = (double)txt_Info.Font.Size;

I tried like that but my programs still have this error: An unhandled exception of type 'System.ArgumentException' occurred in DocX.dll Additional information: Size – Phùng Khánh Hiên May 24 '15 at 14:41
