我可以在C＃中使用变量的值作为属性的名称吗？

Question

How do all!

I want to be able to access a value in a class using the variable passed to a procedure.

eg _results.projection[2].Current.FundDC to become something like

_results.projection[2].termId.varName

where termId can be Current, Future or Percent

and varName can be a large list :)

Any suggestions?

Answers on a postcard please :)

Answer 1

You can do this with reflection using Type.GetProperty to get a PropertyInfo and then PropertyInfo.GetValue to get the value.

Alternatively you could just switch on the name passed to you... both are somewhat icky, to be honest. Is the only way of receiving this information as a string? What's the bigger picture here?
