Expressions (or scripts – the two terms are used interchangeably here) can be used in various places throughout the document. Mark an expression by surrounding it by square brackets, as in the following code:
? Visual Basic
Dim doc As New C1PrintDocument() doc.Body.Children.Add(New RenderText("2 + 2 = [2+2]"))
? C#
C1PrintDocument doc = new C1PrintDocument(); doc.Body.Children.Add(new RenderText("2 + 2 = [2+2]"));
This code will produce the following text in the generated document:
2 + 2 = 4
In this case, the "[2+2]" is interpreted as an expression, and calculated to produce the resulting text.
