【问题描述】：

我在获取更改所提供 Windows 服务密码的代码时遇到问题。

有没有简单的方法来做到这一点。

我得到了这个链接，但它似乎不完整link text

这里他们没有声明 SC_MANAGER_ALL_ACCESS, m_pServiceHandle

有什么建议吗？？谢谢

【解决方案1】：

在托管代码中使用 WMI，每 this site

using System.Management;

string objPath = string.Format("Win32_Service.Name='{0}'", serviceName);
using (ManagementObject service = new ManagementObject(new ManagementPath(objPath)))
{
   object[] wmiParams = new object[11];
   wmiParams[6] = username;
   wmiParams[7] = password;
   service.InvokeMethod("Change", wmiParams);
}

这很完美......
