ASP.NET :: XML-RPC
2005
Using XML-RPC in ASP.NET to call a method on a remote server.
This component used the XML-RPC.NET library (http://xml-rpc.net/) to call a method on a remote server which creates an account on that server. There was also the option of using a separate HTTP Handler component which displayed a progress bar as it waited for a response from the remote server.
This sample of the code shows the part which instantiates and runs the remote procedure call:
Account proxyAccount = new Account();
proxyAccount.Timeout = intProxyTimeout;
IAsyncResult asr;
asr = proxyAccount.BeginCreate(firstname, lastname, email, salesrep, pubkey, authentication, null, null);
while (asr.IsCompleted == false)
{
System.Threading.Thread.Sleep(intSleepTime);
if (useProgressBar)
{
int intProgress = (int)HttpContext.Current.Application["progress_" + strSess];
if (intProgress < (ProgressBarEnd-dblProgressBarStepBy))
{
HttpContext.Current.Application["progress_" + strSess] = (int)Math.Round((double)(intProgress + dblProgressBarStepBy));
}
}
}
strResponse = proxyAccount.EndCreate(asr);
...
The Account class:
[XmlRpcUrl("http://remote.server.com/ws/createaccount.php")]
public class Account : XmlRpcClientProtocol
{
[XmlRpcMethod("remote.account.create")]
public String Create(string firstname, string lastname, string email, string salesrep, string pubkey, string authentication)
{
return (String)Invoke("Create", new object[] {firstname, lastname, email, salesrep, pubkey, authentication});
}
public IAsyncResult BeginCreate(string firstname, string lastname, string email, string salesrep, string pubkey, string authentication, AsyncCallback callback, object asyncState)
{
return BeginInvoke("Create", new object[] {firstname, lastname, email, salesrep, pubkey, authentication}, callback, asyncState);
}
public String EndCreate(IAsyncResult asr)
{
return (String)EndInvoke(asr);
}
}//end of class Account
