Like @layer8 said, pass by copy and pass by value are the same.

C# copies C++ behavior where you can pass a struct by value or reference, and you can mark the parameter as readonly. C# also has in/out parameters. Essentially, you can program in C# exactly like you would in C++.

The footgun with C# structs are that you can accidentally box them onto the heap. To avoid that you can define `ref struct`s that cannot be boxed. `ref struct`s follow the C# disposable pattern.
