Hi there.  I'm trying to figure out if there's a way to reference the runtime value of a matcher for use in a Returns call.  This seems like a pretty straightforward question, but I wasn't able to find quite what I'm wanting in the documentation, so apologies if I missed something obvious.  Regardless, here's the call I'm trying to make.

service.Arrange<Employee>(emp => emp.LoadByName(Arg.AnyString)).Returns(data.employees.Where(e => e.Name == /* whatever the value matched by Arg.AnyString was */));

Is there another method I should be calling to accomplish the same thing, or is there simply a way to reference the matcher's value?

Hello Jonathan,

Just pass a delegate to Returns that has the same number and type of arguments like the arranged method. Like so:

service.Arrange<Employee>(emp => emp.LoadByName(Arg.AnyString))
    .Returns((string name) => data.employees.Where(e => e.Name == name));
