/creditcard/showimage/45809014157220320

Its:

/Transaction/TransactionToPDF/creditcard/showimage/45809014157220320

Answer 1

Wild guess, your Action doesn't accept a null for the image id? Rather than trying to add concatstring try specifying the parameter eg,

@Url.Action("ShowImage", "CreditCard", new { ImageId= ConcatString }) 

Again, depending on what the allowed parameters are for the Action this should let the correct URL be resolved by the routing system

Answer 2

Of course you can use Html.Action helper. But it is easier for me to do it like this.

   <img src="/CreditCard/ShowImage/@ConcatString" class="img float-xs-right" width="350" height="380" id="creditCardImage" /> 

Answer 3

I think you have an "Area" issue. If they are in different areas, you should be able to do this:

@(Url.Action("ShowImage", "CreditCard", new { area = "" }))/" + ConcatString
