Drawing Lines on Canvas and save them as Bild in SVG

Question

Hallo,

 

I need help for my project.

I saw several Tutorials and Examples but I can't still resolve the problem.

I have to save Lines in a database(that I draw on a Canvas) as Bild in SVG Format.  

I read that the SVG is nothing other then an XML data file. That means the SVG will produce a string text at the end.

 

My Questions are:

 

1) shall I first instantiate the XML date file as writer?

2) how can I save a string text <line.../> in svg?

3) do I really need a class library or extern library for SVG in C#? 

 

I hope someone can really suggest me a solution for that.

Thanks in advance!
