Hey, if you make use of the code below then you will able to get the solution for your problem:

public static long IPToLONG(string ipaddressAddress)
{
	System.Net.IPAddress ipaddress;

	if (System.Net.IPAddress.TryParse(ipaddressAddress, out ipaddress))
	{
		byte[] bt = ipaddress.GetAddressBytes();

		return (long)((bt[0] << 24) | (bt[1] << 16) |
			(bt[2] << 8) | bt[3]);
	}
	else
		return 0;
}

Hello, I am not having idea to convert the IP address to Long in ADO, but I can help you to convert the Long value to the IP address. Just make use of the code below:

public static string ConvertLongToIP(long ipLong)
{
	StringBuilder strBuild = new StringBuilder();
	long Two, One;
	Two = ipLong;
	One = Two / (256 * 256 * 256);
	Two = Two - (One * 256 * 256 * 256);
	strBuild.Append(Convert.ToString(One)).Append(".");
	One = Two / (256 * 256);
	Two = Two - (One * 256 * 256);
	strBuild.Append(Convert.ToString(One)).Append(".");
	One = Two / 256;
	Two = Two - (One * 256);
	strBuild.Append(Convert.ToString(One)).Append(".");
	One = Two;
	Two = Two - One;
	strBuild.Append(Convert.ToString(One));
	return strBuild.ToString().ToLower();
}

Hello, I don't know how to convert the IP address to long in ADO.net, But while searching on internet I have got the solution below for achieving it:

function iptolong(ipadr)
	result=0
	str=split(ipadr,".")
	for ix=0 to 3
		expn=3-ix
	result=result + str(ix) * 256 ^ expn
	next
	iptolong=result
end function

Hey, I am having knowledge of C. And that is why I have tried it using c language. I think it will help you to get your logic for your solution:

#include <stdio.h>
#include <string.h>
#include<stdlib.h>
main()
{
int num = 1,z;
long Lnum,longnum2;
char ch[]=" 168.1.2.3";
char *string;
char str2[16];
printf("String: %s\n", str);
string = strtok(str, ".");
 strcpy(str2,string);
 while (1)
{
string = strtok(NULL, ".");
 if (string == NULL)
{
exit(0);
 }
strcat(str2,string);
Lnum=atol(str2);
printf("long integer is %ld \n",Lnum);
}

Hey, hope the solution below will help you and you will get your problem solved. You just need to make use of the code below in your program:

string[] str = Request.UserHostAddress.Split('.');

long ipadd = 19812151 * Convert.ToInt32(str[0]) + 65536 * Convert.ToInt32(str[1]) + 256 * Convert.ToInt32(str[2]) + Convert.ToInt32(str[3]);
