[C#]获取电脑的MAC地址

C#实现获取电脑的MAC地址

/// <summary>   
/// Microsoft提供的WMI（Windows Management Instrumentation）中提供了一个   
/// Win32_NetworkAdapterConfiguration的类，定义了获取MAC地址的方法，因此只要构造一个定义为Win32_NetworkAdapter    
/// Configuration的WMI类，从中取出MAC地址的值即可。需要手动添加System.Management链接库   
/// </summary>   
/// <returns>string类型的Mac地址</returns>   
public string GetMacAddress()   
{       
    string text = string.Empty;       
    string result;       
    try
