WPF; Convert between Path Markup Syntax and Geometry in code behind

I'm looking for conversion between path markup and Geometry. I found a good post showing how to get the Geometry from path markup:

Path Markup Syntax to Geometry

string pathMarkup = "M 100,200 C 100,25 400,350 400,175 H 280";
Geometry myGeometry = Geometry.Parse(pathMarkup);

Geometry to Path Markup Syntax

Now what if I want to get the path markup from the existing geometry?

Geometry myGeometry = //some geometry
string pathMarkup = ??

Any idea how to convert a geometry to its equivalent path markup?

Expanding on Hamlet Hakobyan's answer, unfortunately the ToString() approach only works with Path Geometries. So in order to apply this generically to all Geometry types:

Geometry myGeometry = PathGeometry.Parse("M 8, 0 L 2,25 16,25 Z");
string pathString = myGeometry.ToString(); // Works only for PathGeometry

GeometryGroup geomGroup = new GeometryGroup();
geomGroup.Children.Add(myGeometry);
geomGroup.Transform = myTransform;

string pathString = PathGeometry.CreateFromGeometry(geomGroup).ToString();

What about 

Geometry myGeometry = //some geometry
string pathMarkup = myGeometry.ToString();
