I am trying to convert svg to png nin my asp.net applictaion using c#. I got some help from [here](https://stackoverflow.com/questions/58910/converting-svg-to-png-using-c-sharp). I followed Anish's suggestion . But I am getting exception on this. I dont have idea of this . My code include :

```
            string path = "d:\\";
            string svgstr = temp.Value;
            var byteArray = Encoding.ASCII.GetBytes(svgstr);
            var stream = new MemoryStream(byteArray);
            var bitmap = SvgDocument.Open(stream).Draw();
            bitmap.Save(path, ImageFormat.Png);

```

I am getting following exception on this:
