Can I get C# code of Links of parent-child example like in API guide?

Hi there,

I'm working an API to create a task and link to a project as a child.

I could create a project and a child using C# API, but I cannot find a way to link them as "WorkItemHierarchyLink".

Can I get C# code of Links of parent-child example in "Working with References" in API guide?

Thanks,
