1、Windows下可在CMD控制终端使用Dos命令对指定网卡进行IP配置,需要使用管理员权限打开CMD终端
往网卡添加IP主要有以下两种方法:
方法1:
netsh interface ip add address “网卡名称” IP 掩码 网关
方法2:
netsh interface ip set address \"网卡名称\" static IP 掩码 网关
其中方法1是往指定网卡添加相应的IP地址,并不影响网卡原来的IP配置,方法2是将网卡重置后再添加IP。
删除网卡IP:
netsh interface ip delete address “网卡名称” IP 掩码 网关
2、Qt中的实现原理
头文件:
#include <QProcess>
.cpp文件:
QProcess *process = new QProcess(); QString cmd = "netsh interface ip set address "; cmd += "\"以太网\" "; cmd += "static "; cmd += "173.75.40.20"; cmd += " 255.255.0.0 ";/*开启CMD进程,输入DOS指令*/ process->start(cmd); /*等待CMD进程结束*/
process->waitForFinished();
QString cmd_add = "netsh interface ip add address "; cmd_add += "\"以太网\" "; cmd_add += "173.75.40.12"; cmd_add += " 255.255.0.0 "; process->start(cmd_add); /*等待CMD进程结束*/
process->waitForFinished();
QString cmd_delete = "netsh interface ip delete address ";
cmd_delete += "\"以太网\" ";
cmd_delete += "173.75.40.12";
cmd_delete += " 255.255.0.0 ";
process->start(cmd_delete);
/*等待CMD进程结束*/
process->waitForFinished();
delete process;
process = NULL;
