示例1: ManualResetEvent
// Signals when the resolve has finished.
public static ManualResetEvent GetHostEntryFinished =
new ManualResetEvent(false);
// Define the state object for the callback.
// Use hostName to correlate calls with the proper result.
public class ResolveState
{
string hostName;
IPHostEntry resolvedIPs;
public ResolveState(string host)
{
hostName = host;
}
public IPHostEntry IPs
{
get { return resolvedIPs; }
set { resolvedIPs = value; }
}
public string host
{
get { return hostName; }
set { hostName = value; }
}
}
// Record the IPs in the state object for later use.
public static void GetHostEntryCallback(IAsyncResult ar)
{
ResolveState ioContext = (ResolveState)ar.AsyncState;
ioContext.IPs = Dns.EndGetHostEntry(ar);
GetHostEntryFinished.Set();
}
// Determine the Internet Protocol (IP) addresses for
// this host asynchronously.
public static void DoGetHostEntryAsync(string hostname)
