How to get type of chan with reflect package

Question

Say I have a chan in Go:

var c = make(chan int)

how can discover that it's a channel using:

var isChannel = reflect.ValueOf(c).Kind() == reflect.Chan

but does anyone know how I determine the type of the channel, in this case int?

Answer 1

Use Elem to get the channel type:

var isChannel = reflect.ValueOf(c).Kind() == reflect.Chan
channelType := reflect.ValueOf(c).Type().Elem()

For an int channel, channelType will be int.
