I am trying to use type assertion in golang. with direct assertion there is no problem. 

a, ok := i.(MyStruct)

but when I use reflection

b, ok := i.(reflect.TypeOf(i))

I got an error. What was a problem with that? and How to deal with it?

Full Code:

package main

import (
     "fmt"
     "reflect"
)

type MyStruct struct {
    field string
}

func main() {
    var i interface{} = MyStruct{field:"Thanks"}

    a, ok := i.(MyStruct)
    fmt.Println(a, ok)

    t := reflect.TypeOf(i)
    fmt.Println(t)

    b, ok := i.(t)
    fmt.Println(b, ok)
}

Thank for your answers.
