C# 小工具开源分享之本机IP修改器
前言
工作中，总有修改本机IP的需求，一直都是手动去改，直到坚持不住了……
一个修改IP的小工具开源给大家，地址：https://github.com/hxsfx/hxsfx_IPSet
一、工具演示
选择需要设置的网络（适配器名称），然后根据实际情况设置IP、掩码以及网关，然后点击修改，当出现如下弹框即代表修改成功：
提示：弹窗内容会根据输入的IP等信息发生变化
二、主要代码
1、主要通过NetworkInterface类获取适配器列表
/// 2、通过GetIPProperties()方法获取IP地址、掩码及网关
private void cb_adapter_SelectedIndexChanged(object sender, EventArgs e)
{
foreach (var adapter in NetworkInterfaces)
{
if (adapter.Name == (string)this.cb_adapter.SelectedItem)
{
var p = adapter.GetIPProperties();
var gatewayCollection = p.GatewayAddresses;
if (gatewayCollection.Count > 0)
{
this.textBox_gateway.Text = gatewayCollection[0].Address.ToString();
}
var ipCollection = p.UnicastAddresses;
if (ipCollection.Count > 0)
{
this.textBox_ip.Text = ipCollection[1].Address.ToString();
var ipv4Mask = ipCollection[1].IPv4Mask;
this.textBox_maskCode.Text = ipv4Mask == null ? "" : ipv4Mask.ToString();
}
break;
}
}
}
