c#指定一段ip地址输出

网上找了很多，基本只有这一个版本，但是原作者在移位过程中出现了点问题

private void button1_Click(object sender, EventArgs e)
{
string StartIp = "";
string EndIp = "";
StartIp = Startinput.Text;
EndIp = Endinput.Text;
uint iStartip = ipTint(StartIp);
uint iEndIp = ipTint(EndIp);
//string ip_result="";
StringBuilder ip_result=new StringBuilder();
if (iEndIp >= iStartip)
{
for (uint ip = iStartip; ip <= iEndIp; ip++)
{
ip_result.Append(intTip(ip)).Append("\r\n");
//ip_result = ip_result + intTip(ip)+"\r\n";
}
resultTextBox.Text = ip_result.ToString(); //RichTextBox
}
else
{
MessageBox.Show("起始ip不能小于终止ip");
}
}
public static uint ipTint(string ipStr)
{
string[] ip = ipStr.Split('.');
uint ipcode = 0xFFFFFF00 | byte.Parse(ip[3]);
ipcode = ipcode & 0xFFFF00FF | (uint.Parse(ip[2]) << 0x8);
ipcode = ipcode & 0xFF00FFFF | (uint.Parse(ip[1]) << 0x10);
ipcode = ipcode & 0x00FFFFFF | (uint.Parse(ip[0]) << 0x18);
return ipcode;
}
public static string intTip(uint ipcode)
{

}
