C# 修改IP地址与操作access
C# 修改IP地址,操作access
?
?使用说明
1. 系统必须安装.NET Framework 2.0 或更高的版本 (文件：dotnetfx2.0.exe)。
2. 将压缩包解压即可使用本程序。
3. 必须在管理员权限运行。
4. 如果系统安装杀毒软件或安全卫士，会弹出修改IP的提示，请记住选择，并允许执行。
5. 修改IP地址，必须让网卡连接上网络才能修改。
?
使用方法：
运行软件后，先配置方案，步骤：
? 1.点击软件界面右上角的 【方案配置】
? 2.安装页面添加方案，添加成功后，点击返回。
? 3.方案列表中就会出现刚才添加的新方案。
? 4.选择一个方案，然后选择网卡（如果只有一个网卡联网，可不用选择）
? 5.点击 【更改 IP 地址】 按钮
? 6.等待更改成功。
