Question

.NET System.Environment.MachineName中有一个属性，它读取由于与Windows 98兼容而裁剪的最多15个字符的计算机的名称。

如何获得完整（未裁剪）的名称？

Answer 1

我建议使用 interop

using System.Runtime.InteropServices;
...

[DllImport("KERNEL32.dll", CharSet = CharSet.Auto, BestFitMapping = false)]
private extern static int GetComputerName(
  [Out]StringBuilder nameBuffer, 
  ref int bufferSize);
...

int size = 0; // do not try to return any name, but its actual size only

// What's actual size of the machine name?
GetComputerName(null, ref size);

// Obtaining the machine name 
StringBuilder buffer = new StringBuilder(size);
GetComputerName(buffer, ref size);

string name = buffer.ToString();

您还可以使用WMI获取系统名称

using System.Management;

try
        {
            ManagementObjectSearcher searcher =
                new ManagementObjectSearcher("root\\CIMV2",
                "SELECT Name FROM Win32_ComputerSystem");

            foreach (ManagementObject queryObj in searcher.Get())
            {
                Console.WriteLine("-----------------------------------");
                Console.WriteLine("Win32_ComputerSystem instance");
                Console.WriteLine("-----------------------------------");
                Console.WriteLine("Name: {0}", queryObj["Name"]);
            }
        }
        catch (ManagementException e)
        {
            // exception handling
        }

Environment.MachineName裁剪为15个字符
