I have put lot of efforts, googled and tried all possible ways. But I did not got satisfaction so I come here finally.

I want to convert below line of code [C#] into java.

1] Method used to convert IP into uint

private uint GetIP(string strIp)
       {
           System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse(strIp);
           uint lIp = (uint)ipaddress.Address;
           
           lIp = ((lIp & 0xFF000000) >> 24) + ((lIp & 0x00FF0000) >> 8) + ((lIp & 0x0000FF00) << 8) + ((lIp & 0x000000FF) << 24);
           MessageBox.Show(strIp + " = " + lIp);
           return (lIp);
       }

2] Method used to convert String into IntPtr

IntPtr iPtr = Marshal.StringToHGlobalAnsi("Hello");

Please help me as soon as possible. Thanks in advance.

I really appreciate help.

What I have tried:

I have tried following code for converting IP to Long, not sure is it right or wrong .

public static long ipToLong(String ipAddress) {

String[] ipAddressInArray = ipAddress.split("\\.");

long result = 0;
for (int i = 0; i < ipAddressInArray.length; i++) {

int power = 3 - i;
int ip = Integer.parseInt(ipAddressInArray[i]);
result += ip * Math.pow(256, power);

}

return result;
}

For String to IntPtr, tried to convert String to Ascii and then tried to use Intger by reference.
