c# - 为分布式事务处理协调器 (msdtc.exe) 添加防火墙规则

Question

我尝试使用 firewallAPI.dll 添加规则。它对 calc.exe(或其他一些文件)工作正常，如下所述，但对 msdtc.exe 失败，但出现以下异常:

System.IO.FileNotFoundException: 'The system cannot find the file specified. (Exception from HRESULT: 0x80070002)'

例子:

static void Main(string[] args)
{
    var manager = GetFirewallManager();
    if (manager.LocalPolicy.CurrentProfile.FirewallEnabled)
    {
        var path = @"C:\Windows\System32\calc.exe";
        //var path = @"C:\Windows\System32\msdtc.exe"; // System.IO.FileNotFoundException: 'The system cannot find the file specified.
        AuthorizeApplication("Test", path, NET_FW_SCOPE_.NET_FW_SCOPE_ALL, NET_FW_IP_VERSION_.NET_FW_IP_VERSION_ANY);
    }
}

private const string CLSID_FIREWALL_MANAGER =
    "{304CE942-6E39-40D8-943A-B913C40C9CD4}";

private static NetFwTypeLib.INetFwMgr GetFirewallManager()
{
    Type objectType = Type.GetTypeFromCLSID(
        new Guid(CLSID_FIREWALL_MANAGER));
    return Activator.CreateInstance(objectType)
        as NetFwTypeLib.INetFwMgr;
}

private const string PROGID_AUTHORIZED_APPLICATION =
    "HNetCfg.FwAuthorizedApplication";
public static bool AuthorizeApplication(string title, string applicationPath,
    NET_FW_SCOPE_ scope, NET_FW_IP_VERSION_ ipVersion)
{
    // Create the type from prog id
    Type type = Type.GetTypeFromProgID(PROGID_AUTHORIZED_APPLICATION);
    INetFwAuthorizedApplication auth = Activator.CreateInstance(type)
        as INetFwAuthorizedApplication;
    auth.Name = title;
    auth.ProcessImageFileName = applicationPath;
    auth.Scope = scope;
    auth.IpVersion = ipVersion;
    auth.Enabled = true;

    INetFwMgr manager = GetFirewallManager();
    manager.LocalPolicy.CurrentProfile.AuthorizedApplications.Add(auth);
    return true;
}

注意:我检查了文件夹，发现文件位于正确的位置...有人可以帮助为 分布式事务处理协调器 添加防火墙规则吗？也许我应该尝试向防火墙添加另一个文件(不是 msdtc.exe)？

Project > Properties > Build 选项卡，取消选中“Prefer 32-bit”复选框。你不喜欢它，没有 32 位版本的 msdtc.exe。

为什么文件系统重定向器导致 FileNotFoundException 在 this MSDN article 中有很好的解释.
