How to Convert IPv4 Addresses to Integers and Vice Versa in C#?

Conversion between IPv4 address and integer in C#

When dealing with IPv4 addresses, it is often necessary to convert them to integers or vice versa. C# provides several methods to perform these conversions.

To convert an IPv4 address to an integer, you can use the IPAddress attribute of the class, which returns a 32-bit unsigned integer representing the IPv4 address. However, this property returns the address in network byte order, so the bytes need to be swapped to get host byte order. Address

long address = (long)(uint)IPAddress.NetworkToHostOrder(
    (int)IPAddress.Parse("64.233.187.99").Address);

class: IPAddress

string ipAddress = new IPAddress((uint)IPAddress.HostToNetworkOrder(
    (int)address)).ToString();
