Currency Convertor API

ASP.NET Exchange Rate API

http://exchangerate-api.com/asp-net

Before you start using this API you need a (free) API key, which you can get here
Once you've done that, using the Exchange Rate API in ASP.NET is easy. Here are some examples to convert currencies:


To convert currencies from 12.50 USD (US Dollar) to GBP (British Pound)
Dim answer As String
Dim url As String
url = "www.exchangerate-api.com/usd/gbp/12.50?k=API_KEY"
Dim inStream As StreamReader
Dim webRequest As WebRequest
Dim webresponse As WebResponse
webRequest = webRequest.Create(url)
webresponse = webRequest.GetResponse()
inStream = New StreamReader(webresponse.GetResponseStream())
answer = inStream.ReadToEnd()

Or to get how many Japanese Yen (JPY) there are to the South African Rand (ZAR):

Dim answer As String
Dim url As String
url = "www.exchangerate-api.com/zar/jpy?k=API_KEY"
Dim inStream As StreamReader
Dim webRequest As WebRequest
Dim webresponse As WebResponse
webRequest = webRequest.Create(url)
webresponse = webRequest.GetResponse()
inStream = New StreamReader(webresponse.GetResponseStream())
answer = inStream.ReadToEnd()

How to Fix Error- Sys.WebForms.PageRequestManagerTimeoutException - The server request timed out

For example if you want that the timeout will take maximum 10 minutes your code should be look like this: < asp : ScriptManager ID ="ScriptManager1" runat ="server" AsyncPostBackTimeOut ="600" > </ asp : ScriptManager >       * The default value of the AsyncPostBackTimeOut property is 90 seconds.
