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

/// <summary>
/// 初始化适配器（以太网）名称列表
/// </summary>
private void InitalNetworkInterfaceName()
{
    this.NetworkInterfaces = NetworkInterface.GetAllNetworkInterfaces();
    foreach (var adapter in this.NetworkInterfaces)
    {
        if (adapter.OperationalStatus == OperationalStatus.Up)
        {
            if (adapter.NetworkInterfaceType == NetworkInterfaceType.Ethernet
            || adapter.NetworkInterfaceType == NetworkInterfaceType.Wireless80211)
            {
                this.cb_adapter.Items.Add(adapter.Name);
            }
        }
    }
    if (this.cb_adapter.Items.Count > 0)
    {
        this.cb_adapter.SelectedIndex = 0;
    }
}

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;
        }
    }
}
