1. 在ASP.NET 中專用屬性：
獲取服務器電腦名：Page.Server.ManchineName
獲取用戶信息：Page.User
獲取客戶端電腦名：Page.Request.UserHostName
獲取客戶端電腦IP：Page.Request.UserHostAddress
2. 在網(wǎng)絡編程中的通用方法：
獲取當前電腦名：static System.Net.Dns.GetHostName()
根據(jù)電腦名取出全部IP地址：static System.Net.Dns.Resolve(電腦名).AddressList
也可根據(jù)IP地址取出電腦名：static System.Net.Dns.Resolve(IP地址).HostName
3. 系統(tǒng)環(huán)境類的通用屬性：
當前電腦名：static System.Environment.MachineName
當前電腦所屬網(wǎng)域：static System.Environment.UserDomainName
當前電腦用戶：static System.Environment.UserName
一個獲取本機內(nèi)網(wǎng)和外網(wǎng)IP的公用類
