怎么使用呢？So easy！下面演示将 WLAN 2 适配器的 DNS 设置为谷歌的：
List<TSAdapter> Adps = TSAdapter.GetAdapters();
foreach (TSAdapter adp in Adps)
{
if (adp.Name == "WLAN 2")
{
try
{
adp.DNS = new string[] { "8.8.8.8" };
textBox1.Text = "OK";
}
catch (TSAdapterSetException ee)
{
MessageBox.Show("设置时发生错误：" + ee.Source,
"TSLib");
}
break;
}
}
当然所有功能不能一一演示，用对象浏览器来看吧，全都加好 summary 的~
