Question

关注the guidance posted on MSDN as to how to create an application partition我在删除刚刚创建的分区时遇到异常。以下示例针对我的用户帐户具有完全管理权限的AD LDS实例运行。有趣的是，如果在使用测试夹具之前存在分区，它会第一次工作。

var connectionString = new Uri("LDAPS://localhost/DC=integrationtests,DC=contoso,DC=com");
var baseContainerName = connectionString.PathAndQuery.TrimStart('/');
var hostName = IPGlobalProperties.GetIPGlobalProperties().HostName;
var directoryContext = new DirectoryContext(DirectoryContextType.DirectoryServer, hostName);
var configurationSet = ConfigurationSet.GetConfigurationSet(directoryContext);

var existingPartition =
                configurationSet.ApplicationPartitions.Cast<ApplicationPartition>().FirstOrDefault(
                    partition => baseContainerName.Equals(partition.Name, StringComparison.OrdinalIgnoreCase));
if (existingPartition != null)
{
    existingPartition.Delete();
}

// DirectoryEntry requires that the scheme is uppercase (LDAP not ldap)
var authenticationOptions = AuthenticationTypes.FastBind | AuthenticationTypes.Delegation | AuthenticationTypes.Secure;
var ldapConnectionString = String.Format(CultureInfo.InvariantCulture, "LDAP://{0}", hostName);
if (connectionString.Scheme.Equals("LDAPS", StringComparison.OrdinalIgnoreCase))
{
    authenticationOptions = authenticationOptions | AuthenticationTypes.SecureSocketsLayer;
    ldapConnectionString = ldapConnectionString + ":" + (connectionString.Port <= 0 ? "636" : connectionString.Port.ToString(CultureInfo.InvariantCulture));
}
using (var parent = new DirectoryEntry(ldapConnectionString, null, null, authenticationOptions))
{
    var partition = parent.Children.Add(baseContainerName, "domainDns");
    partition.Properties["instanceType"].Value = 5;
    partition.Properties["description"].Value = Assembly.GetExecutingAssembly().GetName().Name;
    partition.CommitChanges();
}

var existingPartition2 =
                configurationSet.ApplicationPartitions.Cast<ApplicationPartition>().FirstOrDefault(
                    partition => baseContainerName.Equals(partition.Name, StringComparison.OrdinalIgnoreCase));
if (existingPartition2 != null)
{
    // Throws here
    existingPartition2.Delete();
}

对existingPartition2.Delete（）的调用抛出：

System.DirectoryServices.ActiveDirectory.ActiveDirectoryOperationException was unhandled
HResult=-2146233088
Message=There is no such object on the server.

            at System.DirectoryServices.ActiveDirectory.ApplicationPartition.Delete()

有关可能导致第二次投掷的原因的任何想法？我可以在调用之前使用ADSIEdit在适当的位置看到crossRef对象。

在解决了Microsoft的问题（PSS案例＃112072417632086）后，发现ConfigurationSet类维护了一个缓存，如果您进行了更改，则需要刷新。不是很明显，我知道......在第二个分区存在之前，检查调用刷新它：

configurationSet = ConfigurationSet.GetConfigurationSet(directoryContext.Value);

删除应用程序分区会抛出对象不存在的异常
