我正在尝试在互联网上找到这方面的文档时遇到了最糟糕的情况。本质上，我想知道 Secpol MaXPWAge 设置为 90 或更少，并将其显示在文本框中（为方便起见，我们称其为 textbox1） 我在审计员中搜索了 WMI 解决方案、注册表、GPEDIT，但一无所获。我确实找到了这个，但老实说，我不知道如何使用相同的代码来检查 Max Password Age 而不是复杂性要求。请，有人可以告诉我我应该在这里做什么吗？C# 不是我的主要语言。

    {
        var tempFile = Path.GetTempFileName();

        Process p = new Process();
        p.StartInfo.FileName = Environment.ExpandEnvironmentVariables(@"%SystemRoot%\system32\secedit.exe");
        p.StartInfo.Arguments = String.Format(@"/export /cfg ""{0}"" /quiet", tempFile);

        p.StartInfo.UseShellExecute = false;
        p.Start();
        p.WaitForExit();

        var file = IniFile.Load(tempFile);

        IniSection systemAccess = null;

            && Int32.TryParse(passwordComplexityString, out passwordComplexity)
            && passwordComplexity == 1;

这是一种欺骗，但如果你只是在寻找那一件事，它就会起作用。基本上它会启动一个新进程并运行net accounts，然后Maximum password age从输出中退出该字段。试试看，但您可能必须以管理员身份运行它：

var process = new Process
{
    StartInfo = new ProcessStartInfo()
    {
        FileName = "net",
        Arguments = "accounts",
        UseShellExecute = false,
        RedirectStandardOutput = true,
        CreateNoWindow = true
    }
};

process.Start();
string text = "";
while (!process.StandardOutput.EndOfStream)
{
    text = process.StandardOutput.ReadLine();
    if (text != null && text.StartsWith("Maximum password age (days):"))
        break;
}
if (text == null || !text.StartsWith("Maximum password age (days):"))
    return;
text = text.Replace("Maximum password age (days):", "").Trim();

textBox1.Text = text;

我会这样写IniFile课程：

class IniFile : Dictionary<string,Dictionary<string,string>> {
    public IniFile(string filename) {
        var currentSection = new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase);
        Add("", currentSection);
        foreach (var line in File.ReadAllLines(filename)) {
            var trimedLine = line.Trim();
            switch (line[0]) {
                case ';':
                    continue;
                case '[':
                    currentSection = new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase);
                    Add(trimedLine.Substring(1, trimedLine.Length - 2), currentSection);
                    break;
                default:
                    var parts = trimedLine.Split('=');
                    if (parts.Length > 1) {
                        currentSection.Add(parts[0].Trim(), parts[1].Trim());
                    }
                    break;
            }
        }
    }
    public string this[string sectionName, string key] {
        get {
            Dictionary<string, string> section;
            if (!TryGetValue(sectionName, out section)) { return null; }
            string value;
            if (!section.TryGetValue(key, out value)) { return null; }
            return value;
        }
    }
    public int? GetInt(string sectionName, string key) {
        string stringValue = this[sectionName, key];
        int result;
        if (!int.TryParse(stringValue, out result)) { return null; }
        return result;
    }
}

并将ini文件生成放入单独的方法中：

class Program {
    static void GenerateSecEditOutput(out string tempFile) {
        tempFile = Path.GetTempFileName();
        var p = new Process {
            StartInfo = new ProcessStartInfo {
                FileName = Environment.ExpandEnvironmentVariables(@"%SystemRoot%\system32\secedit.exe"),
                Arguments = String.Format(@"/export /cfg ""{0}"" /quiet", tempFile),
                CreateNoWindow = true,
                UseShellExecute = false
            }
        };
        p.Start();
        p.WaitForExit();
    }

    //... Main goes here
}

然后，该Main方法如下所示：

static void Main(string[] args) {
    //This will be the path of the temporary file which contains the output of secedit.exe
    string tempFile;

    //Write the output of secedit.exe to the temporary file
    GenerateSecEditOutput(out tempFile);

    //Parse the temporary file
    var iniFile = new IniFile(tempFile);

    //Read the maximum password age from the "System Access" section
    var maxPasswordAge = iniFile.GetInt("System Access", "MaximumPasswordAge");
    if (maxPasswordAge.HasValue) {
        Console.WriteLine("MaxPasswordAge = {0}", maxPasswordAge);
    } else {
        Console.WriteLine("Unable to find MaximumPasswordAge");
    }
    Console.ReadKey(true);
}

如果您有一些文本框要将值放入其中，则步骤或多或少是相同的。我们可以避免整数解析，并使用索引器IniFile：

string tempFile;
GenerateSecEditOutput(out tempFile);
var iniFile = new IniFile(tempFile);
//assuming tb is a variable referring to a textbox
tb.Text = iniFile["System Access", "MaximumPasswordAge"];

请记住，这secedit.exe需要管理员权限才能运行。没有管理员权限，代码不会失败；临时文件将只是空的。有关如何执行此操作的一些建议，请参见此处。
