Modifying body of method with Roslyn

Is there some way to add a specific statement at the end of a method in a .cs file with Roslyn?

var code = new StreamReader(@"C:\Users\PersonalUser\Documents\Visual Studio 2015\Projects\SampleToAnalyze\SampleToAnalyze\ClassChild.cs").ReadToEnd();
SyntaxTree tree = CSharpSyntaxTree.ParseText(code);
var root = tree.GetRoot();
var compilation = CSharpCompilation.Create("MyCompilation", new[] { tree },
          new[] { MetadataReference.CreateFromFile(typeof(object).Assembly.Location) });
var model = compilation.GetSemanticModel(tree);

MethodDeclarationSyntax myMethod= tree.GetRoot().DescendantNodes()
                                      .OfType<MethodDeclarationSyntax>().Last();

StatementSyntax myStatement= SyntaxFactory.ParseStatement(@"Console.WriteLine();");

I want to insert "myStatement" at the end of method "myMethod".
