my Code:

var svg = new SKSvg(); svg.FromSvg(strSVG);

strSVG is the above string from database

I am getting an exception:

Decode string first

[AlanFloyd]

Many thanks. Not very sure how to do this, like this?

public static string DecodeBase64ToString(string valor) { byte[] myBase64ret = Convert.FromBase64String(valor); string myStr = System.Text.Encoding.UTF8.GetString(myBase64ret); return myStr; }
