Blank Lines

Question

What does this mean? Can you give example?

4.2.1.1 One blank line is always used in between the local variables in a method and its first statement

4.2.1.2 One blank line is always used after the closing of a code block that is not followed by another closing code.

Those look like some 'style' guidelines for writing VB.NET code - they're certainly not compulsory. The first one means that you first declare the local variables used in a method and then leave a blank line before the executable code. The second one means that you should always leave a blank line after closing a code block (If, For, While etc statements) unless it's followed by the closure of another code block in which it's nested. For example: Public Sub MyMethod() Dim i As Integer = 1 Dim j As Integer = 2 Dim k As Integer Dim l As Integer Dim m As Integer Dim n As Integer = 0 k = i + j ' leave blank line after variable declarations For l = 0 To i For m = j To k n += l * m Next m ' no blank line as followed by another Next statement Next n ' leave blank line as Next not followed by another closure Console.WriteLine(n) End Sub
