private void GeoCode_Method1(string myaddress, int waypointIndex, string callingUser)
{          
    GCService.GeocodeCompleted += new EventHandler<NSpace.GCService.GeocodeCompletedEventArgs>(GeoCode_Method1_GeocodeCompleted);
    GCService.GeocodeAsync(request, waypointIndex);
}

void GeoCode_Method1_GeocodeCompleted(object sender, NSpace.GCService.GeocodeCompletedEventArgs e) 
{
   //***QUESTION: how do I access variable "callinguser" from GeoCode_Method1 in this method??
}

当我调用 GeoCode_Method1 时，我发送“callinguser”字符串变量，并且我想在 GeoCode_Method1_GeocodeCompleted 中访问它（异步 GeoCodingAsync 调用完成时触发）。我该怎么做呢？
