新建层次关系如下：

下面我们开始连接域，并读取出示例准备中键好的组织单位和用户 首先编写代码用

LDAP 尝试对域进行访问

形式：LDAP://Domain

#region## 是否连接到域

///

/// 域名或IP

/// 用户名

/// 密码

/// 域

///

private bool IsConnected(string domainName, string userName, string userPwd, out DirectoryEntry domain)

{

domain = new DirectoryEntry();

try

{

domain.Path = string.Format("LDAP://{0}", domainName);

domain.Username = userName;

domain.Password = userPwd;

domain.AuthenticationType = AuthenticationTypes.Secure;

domain.RefreshCache();

return true;

}

catch(Exception ex)

{

LogRecord.WriteLog("[IsConnected方法]错误信息：" ex.Message);

return false;

}

} #endregion

传用参数，调IsConnected 方法，结果如下

连接上AD 域后，接着我们找到根OU

#region## 域中是否存在组织单位

///

///

///

///

private bool IsExistOU(DirectoryEntry entry, out DirectoryEntry ou)

{

ou = new DirectoryEntry();

try

{

ou = entry.Children.Find("OU=" txtRootOU.Text.Trim());

return (ou != null);

}

catch(Exception ex)

{

LogRecord.WriteLog("[IsExistOU方法]错误信息：" ex.Message);

return false;

}

} #endregion

传入以数，调用IsExistOU 方法，结果如下

下面来开始读取组织单位及用户的信息。

示例为了看出层次关系及导出信息是类型区分，给OU 和User 新建了一个实体类和一个类型的枚举

#region## 类型

///

public enum TypeEnum : int

{

///

OU = 1,

///

USER = 2 }

#endregion

#region## Ad域信息实体

///

public class AdModel

{

public AdModel(string id, string name, int typeId, string parentId) {

Id = id;

Name = name;

TypeId = typeId;

ParentId = parentId;

}

public string Id { get; set; }

public string Name { get; set; }

public int TypeId { get; set; }

public string ParentId { get; set; }

}

#endregion

下面读取信息

private List list = new List();

#region## 同步

///

///

public void SyncAll(DirectoryEntry entryOU)

{

DirectorySearcher mySearcher = new DirectorySearcher(entryOU, "(objectclass=organizationalUnit)"); //查询组织单位

DirectoryEntry root = mySearcher.SearchRoot; //查找根OU

SyncRootOU(root);

StringBuilder sb = new StringBuilder();

sb.Append("rnIDt帐号t类型t父IDrn");

foreach (var item in list)

{

sb.AppendFormat("{0}t{1}t{2}t{3}rn", item.Id, item.Name, item.TypeId, item.ParentId);

}

LogRecord.WriteLog(sb.ToString());

MessageBox.Show("同步成功", this.Text, MessageBoxButtons.OK,

MessageBoxIcon.Information);

Application.Exit();

}

#endregion

#region## 同步根组织单位

///

///

private void SyncRootOU(DirectoryEntry entry)

{

if (entry.Properties.Contains("ou") &&

entry.Properties.Contains("objectGUID"))

{

string rootOuName = entry.Properties["ou"][0].ToString();

byte[] bGUID = entry.Properties["objectGUID"][0] as byte[];

string id = BitConverter.ToString(bGUID);

list.Add(new AdModel(id, rootOuName, (int)TypeEnum.OU, "0"));

SyncSubOU(entry, id);

}

}

#endregion

#region## 同步下属组织单位及下属用户

///

///

///

private void SyncSubOU(DirectoryEntry entry, string parentId)

{

foreach (DirectoryEntry subEntry in entry.Children)

{

string entrySchemaClsName = subEntry.SchemaClassName;

string[] arr = subEntry.Name.Split('=');

string categoryStr = arr[0];

string nameStr = arr[1];

string id = string.Empty;

if (subEntry.Properties.Contains("objectGUID")) //SID

{

byte[] bGUID = subEntry.Properties["objectGUID"][0] as byte[];

id = BitConverter.ToString(bGUID);

}

bool isExist = list.Exists(d => d.Id == id);

switch (entrySchemaClsName)

{

case "organizationalUnit":

if (!isExist)

{

list.Add(new AdModel(id, nameStr, (int)TypeEnum.OU, parentId)); }

SyncSubOU(subEntry, id);

break;

case "user":

string accountName = string.Empty;

if (subEntry.Properties.Contains("samaccountName"))

{

accountName =

subEntry.Properties["samaccountName"][0].ToString();

}

if (!isExist)

{

list.Add(new AdModel(id, accountName, (int)TypeEnum.USER,

parentId));

}

break;

}

}

}

#endregion

调用SyncAll 方法循环输出list, 结果如下, 很清楚的可以看出层次关系
