3 years ago Ah. It looks like it works when you don't call Close() after Write().

I have this code in a wpf window's Loaded event handler. Just above this block of code is where I create "graph". The line "svgGraphWriter.Close();" at the end throws an exception. svgGraphWriter.Write(); creates the file and writes it to "path" without issues, so this is weird to me. I would think this would be a straightforward use of svgGraphWriter, since you don't want to keep its Stream open once the svg is created. Below are the exception details.
GraphRenderer renderer = new GraphRenderer(graph); renderer.CalculateLayout(); SvgGraphWriter svgGraphWriter = new SvgGraphWriter(new FileStream(path, FileMode.OpenOrCreate), graph); svgGraphWriter.AllowedToWriteUri = true; svgGraphWriter.Write(); svgGraphWriter.Close();
