How to check Public IP addresses already associated with the other resources using Fluent API

I want to find out weather selected IP address is associated with other resources or not suing Fluent API .

Below is my code right now :

var publicIp = _azureClient.PublicIPAddresses.ListByResourceGroup(requestObject.ResourceGroupName);
var publicIpList = new List<PublicIpObject>();
foreach (var ip in publicIp)
var pubIpObj = new PublicIpObject();
if (ip != null && ip.Sku.Equals("Standard") && ip.IPAllocationMethod.Equals("Static"))
pubIpObj.PublicIpAddressName = ip.Name;
pubIpObj.PublicIpSku = ip.Sku.ToString();
pubIpObj.IsAttachedToNic = ip.HasAssignedNetworkInterface;
pubIpObj.IsAttachedToLoadBalancer = ip.HasAssignedLoadBalancer;
pubIpObj.PublicIpAssignment = ip.IPAllocationMethod.ToString();
return publicIpList;

    @Dnyaneshwar Surywanshi Thank you for reaching out.
    We sincerely apologize for the delay in getting back to you.

    You can use IpConfiguration property to check if the IP is already associated with any other resource.

        var publicip1 = await azure.PublicIPAddresses.GetByIdAsync("/subscriptions/XXXXX-c5b6-44fb-b5ba-XXXXX/resourceGroups/XXXX-testing/providers/Microsoft.Network/publicIPAddresses/pip1-intlb1-22899143b");  
        if (publicip1.Inner.IpConfiguration == null)  
            Console.WriteLine("IP Address is not associated");  
            Console.WriteLine("IP Address is already associated");  

    Please let us know if you have any further questions.
