c# - 以编程方式编辑 IIS IPGrant 表

Question

我一直致力于在 IIS 中编辑 IPGrant 表的编程解决方案。

就目前而言，我可以正确查看 IPGrant 列表，并可以添加到它。

但是，我无法删除或替换 IPGrant 列表中的项目。

MSDN 等建议您将(旧列表的值 + 新值)写入列表，但是我发现我得到的 HResult 是“无法使用该名称创建文件，文件已存在” .添加到列表仅适用于我如果我只传入新值。

我发现 IIS 7/6 和使用元数据库存在兼容性问题 - 因为元数据库只能添加，不能删除。

IIS 7/7.5 是否有更新的方法可用于(请在 c# 中)管理 IPGrant 表。

您可以使用 Microsoft.Web.Administration、AppCmd 或 Javascript (COM - AHADMIN) 来执行此操作，以下是有关如何删除的几个示例:

private static void Main() {

    using(ServerManager serverManager = new ServerManager()) { 
        Configuration config = serverManager.GetApplicationHostConfiguration();

        ConfigurationSection ipSecuritySection = config.GetSection("system.webServer/security/ipSecurity");

        ConfigurationElementCollection ipSecurityCollection = ipSecuritySection.GetCollection();

        ConfigurationElement addElement = FindElement(ipSecurityCollection, "add", "ipAddress", @"169.132.124.234", "subnetMask", @"255.255.255.255", "domainName", @"");
        if (addElement == null) throw new InvalidOperationException("Element not found!");

        ipSecurityCollection.Remove(addElement);

        serverManager.CommitChanges();
    }
}

private static ConfigurationElement FindElement(ConfigurationElementCollection collection, string elementTagName, params string[] keyValues) {
    foreach (ConfigurationElement element in collection) {
        if (String.Equals(element.ElementTagName, elementTagName, StringComparison.OrdinalIgnoreCase)) {
            bool matches = true;

            for (int i = 0; i < keyValues.Length; i += 2) {
                object o = element.GetAttributeValue(keyValues[i]);
                string value = null;
                if (o != null) {
                    value = o.ToString();
                }

                if (!String.Equals(value, keyValues[i + 1], StringComparison.OrdinalIgnoreCase)) {
                    matches = false;
                    break;
                }
            }
            if (matches) {
                return element;
            }
        }
    }
    return null;
}

使用 Javascript:

var adminManager = new ActiveXObject('Microsoft.ApplicationHost.WritableAdminManager');adminManager.CommitPath = "MACHINE/WEBROOT/APPHOST";

var ipSecuritySection = adminManager.GetAdminSection("system.webServer/security/ipSecurity", "MACHINE/WEBROOT/APPHOST");

var ipSecurityCollection = ipSecuritySection.Collection;

var addElementPos = FindElement(ipSecurityCollection, "add", ["ipAddress", "169.132.124.234","subnetMask", "255.255.255.255","domainName", ""]);if (addElementPos == -1) 抛出“找不到元素!”；

ipSecurityCollection.DeleteElement(addElementPos);

adminManager.CommitChanges();

function FindElement(collection, elementTagName, valuesToMatch) { 对于 (var i = 0; i < collection.Count; i++) { var element = collection.Item(i);

    if (element.Name == elementTagName) {
        var matches = true;
        for (var iVal = 0; iVal < valuesToMatch.length; iVal += 2) {
            var property = element.GetPropertyByName(valuesToMatch[iVal]);
            var value = property.Value;
            if (value != null) {
                value = value.toString();
            }
            if (value != valuesToMatch[iVal + 1]) {
                matches = false;
                break;
            }
        }
        if (matches) {
            return i;
        }
    }
}

return -1;

最后是 AppCmd.exe:
appcmd.exe set config -section:system.webServer/security/ipSecurity/-[ipAddress='169.132.124.234',subnetMask='255.255.255.255',domainName='']"/commit:apphost
