C# Google Custom Search API by Image (Reverse Image Search)

[Met Gen]

Hello.

I'm using Google Custom Search API with C#. 

I can search only images by string such as "cars". That's good.

But i want to search similiar or same images on the internet by selected image (which selected from my documents)

How can i do that.

codes below which i used to string search for images

        Dim searchterm As String = "cars"
        Dim svc = New CustomsearchService(New BaseClientService.Initializer() With { _
         .ApiKey = "*********" _
        })
        Dim listRequest = svc.Cse.List(searchTerm)

        listRequest.SearchType = CseResource.ListRequest.SearchTypeEnum.Image
        listRequest.Cx = "*********"
        listRequest.ImgSize = CseResource.ListRequest.ImgSizeEnum.Medium
        listRequest.Num = 10
        Dim resultItems = New List(Of Google.Apis.Customsearch.v1.Data.Result)()
        listRequest.Start = 1
        Dim search = listRequest.Execute()
        resultItems.AddRange(search.Items)

I need to modify searchterm i think. But how :)

Thanks Inadvance.

Unfortunately, Google doesn't offer their search-by-image service through an API. You'll have to use something else.
