NetworkToHostOrder Method (Int64)

IPAddress.NetworkToHostOrder Method (Int64)

Converts a long value from network byte order to host byte order.

Namespace:  System.Net
Assembly:  System.Net (in System.Net.dll)

public static long NetworkToHostOrder(
	long network


Type: System.Int64
The number to convert, expressed in network byte order.

Return Value

Type: System.Int64
A long value, expressed in host byte order.

Different computers use different conventions for ordering the bytes within multibyte integer values. Some computers put the most significant byte first (known as big-endian order) and others put the least-significant byte first (known as little-endian order). To work with computers that use different byte ordering, all integer values that are sent over the network are sent in network byte order which has the most significant byte first.

The NetworkToHostOrder method converts multibyte integer values that are stored on the host system from the byte order used by the network to the byte order used by the host.

The following example uses the NetworkToHostOrder method to convert a long value from network byte order to host byte order.

long networkByteLong = 1228638273342013440;
long hostByteLong;
// Converts a long value from network byte order to host byte order.
hostByteLong = IPAddress.NetworkToHostOrder(networkByteLong);
outputBlock.Text += "Network byte order to Host byte order of ";
outputBlock.Text += networkByteLong;
outputBlock.Text += " is ";
outputBlock.Text += hostByteLong;
outputBlock.Text += "\n";
