其他答案描述不佳,没有描述如何实现它们,并且大多数给出了错误的过滤器属性。你甚至不需要使用.Filter——你可以将你的属性(姓氏=.Surname,名字=.GivenName)分配给UserPrincipal对象,然后使用@987654325搜索那个对象@ 在任何触发搜索的事件中:
string firstName = txtFirstName.Text;
string lastName = txtLastName.Text;
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
UserPrincipal up = new UserPrincipal(ctx);
if (!String.IsNullOrEmpty(firstName))
up.GivenName = firstName;
if (!String.IsNullOrEmpty(lastName))
up.Surname = lastName;
PrincipalSearcher srch = new PrincipalSearcher(up);
srch.QueryFilter = up;
我假设您有用于获取名字和姓氏的文本框,ID/名称为txtFirstName 和txtLastName。请注意,如果您要查找的属性中没有值,请不要将其添加到UserPrincipal,否则会导致异常。这就是我在上面包含检查的原因。
然后您对srch 执行.FindAll 以将搜索结果放入PrincipalSearchResult 集合中的Principal 对象:
using (PrincipalSearchResult<Principal> results = srch.FindAll())
{
if (results != null)
{
int resultCount = results.Count();
if (resultCount > 0) // we have results
{
foreach (Principal found in results)
{
string username = found.SamAccountName; // Note, this is not the full user ID! It does not include the domain.
}
}
}
}
请注意,即使它的.Count() 是0,结果也不会为空,以及为什么两个检查都存在。
您使用 foreach 进行迭代以获取所需的属性,这回答了如何使用 C# 在 AD 中查找用户的问题,但请注意,您只能使用 Principal 对象访问一些属性,如果我通过谷歌(像我一样)提出这个问题,我会非常沮丧。如果你发现这就是你所需要的——太好了,你就完成了!但为了得到其余的(并让我自己的良心安息),你必须潜入水中,我将描述如何做到这一点。
我发现你不能只使用我上面提到的username,但你必须得到整个DOMAIN\doej 这样的名字。这就是你这样做的方式。相反,将其放在上面的 foreach 循环中:
string userId = GetUserIdFromPrincipal(found);
并使用此功能:
private static string GetUserIdFromPrincipal(Principal prin)
{
string upn = prin.UserPrincipalName;
string domain = upn.Split('@')[1];
domain = domain.Substring(0, domain.IndexOf(".YOURDOMAIN"));
// "domain" will be the subdomain the user belongs to.
// This may require edits depending on the organization.
return domain + @"\" + prin.SamAccountName;
}
一旦你有了它,你就可以调用这个函数了:
public static string[] GetUserProperties(string strUserName)
{
UserPrincipal up = GetUser(strUserName);
if (up != null)
{
string firstName = up.GivenName;
string lastName = up.Surname;
string middleInit = String.IsNullOrEmpty(up.MiddleName) ? "" : up.MiddleName.Substring(0, 1);
string email = up.EmailAddress;
string location = String.Empty;
string phone = String.Empty;
string office = String.Empty;
string dept = String.Empty;
DirectoryEntry de = (DirectoryEntry)up.GetUnderlyingObject();
DirectorySearcher ds = new DirectorySearcher(de);
ds.PropertiesToLoad.Add("l"); // city field, a.k.a location
ds.PropertiesToLoad.Add("telephonenumber");
ds.PropertiesToLoad.Add("department");
ds.PropertiesToLoad.Add("physicalDeliveryOfficeName");
SearchResultCollection results = ds.FindAll();
if (results != null && results.Count > 0)
{
ResultPropertyCollection rpc = results[0].Properties;
foreach (string rp in rpc.PropertyNames)
{
if (rp == "l") // this matches the "City" field in AD properties
location = rpc["l"][0].ToString();
if (rp == "telephonenumber")
phone = FormatPhoneNumber(rpc["telephonenumber"][0].ToString());
if (rp == "physicalDeliveryOfficeName")
office = rpc["physicalDeliveryOfficeName"][0].ToString();
if (rp == "department")
dept = rpc["department"][0].ToString();
}
}
string[] userProps = new string[10];
userProps[0] = strUserName;
userProps[1] = firstName;
userProps[2] = lastName;
userProps[3] = up.MiddleName;
userProps[4] = middleInit;
userProps[5] = email;
userProps[6] = location;
userProps[7] = phone;
userProps[8] = office;
userProps[9] = dept;
return userProps;
}
else
return null;
}
/// <summary>
/// Returns a UserPrincipal (AD) user object based on string userID being supplied
/// </summary>
/// <param name="strUserName">String form of User ID: domain\username</param>
/// <returns>UserPrincipal object</returns>
public static UserPrincipal GetUser(string strUserName)
{
PrincipalContext oPrincipalContext = new PrincipalContext(ContextType.Domain);
try
{
UserPrincipal oUserPrincipal = UserPrincipal.FindByIdentity(oPrincipalContext, strUserName);
return oUserPrincipal;
}
catch (Exception ex) { return null; }
}
public static string FormatPhoneNumber(string strPhoneNumber)
{
if (strPhoneNumber.Length > 0)
// return String.Format("{0:###-###-####}", strPhoneNumber); // formating does not work because strPhoneNumber is a string and not a number
return Regex.Replace(strPhoneNumber, @"(\d{3})(\d{3})(\d{4})", "$1-$2-$3");
else
return strPhoneNumber;
}
请注意,FormatPhoneNumber 函数适用于北美号码。它将获取一个找到的数字 (##########) 并将其拆分为 ###-###-####。
然后您可以在 foreach 循环中获取这样的属性:
string[] userProps = GetUserProperties(userId);
string office = userProps[8];
但是,作为一个整体解决方案,您甚至可以将这些结果添加到 DataRow 列中,并将其作为 DataTable 的一部分返回,然后您可以绑定到 ListView或GridView。我就是这样做的,发送一个List<string>,里面填满了我需要的属性:
/// <summary>
/// Gets matches based on First and Last Names.
/// This function takes a list of acceptable properties:
/// USERNAME
/// MIDDLE_NAME
/// MIDDLE_INITIAL
/// EMAIL
/// LOCATION
/// PHONE
/// OFFICE
/// DEPARTMENT
///
/// The DataTable returned will have columns with these names, and firstName and lastName will be added to a column called "NAME"
/// as the first column, automatically.
/// </summary>
/// <param name="firstName"></param>
/// <param name="lastName"></param>
/// <param name="props"></param>
/// <returns>DataTable of columns from "props" based on first and last name results</returns>
public static DataTable GetUsersFromName(string firstName, string lastName, List<string> props)
{
string userId = String.Empty;
int resultCount = 0;
DataTable dt = new DataTable();
DataRow dr;
DataColumn dc;
// Always set the first column to the Name we pass in
dc = new DataColumn();
dc.DataType = System.Type.GetType("System.String");
dc.ColumnName = "NAME";
dt.Columns.Add(dc);
// Establish our property list as columns in our DataTable
if (props != null && props.Count > 0)
{
foreach (string s in props)
{
dc = new DataColumn();
dc.DataType = System.Type.GetType("System.String");
if (!String.IsNullOrEmpty(s))
{
dc.ColumnName = s;
dt.Columns.Add(dc);
}
}
}
// Start our search
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
UserPrincipal up = new UserPrincipal(ctx);
if (!String.IsNullOrEmpty(firstName))
up.GivenName = firstName;
if (!String.IsNullOrEmpty(lastName))
up.Surname = lastName;
PrincipalSearcher srch = new PrincipalSearcher(up);
srch.QueryFilter = up;
using (PrincipalSearchResult<Principal> results = srch.FindAll())
{
if (results != null)
{
resultCount = results.Count();
if (resultCount > 0) // we have results
{
foreach (Principal found in results)
{
// Iterate results, set into DataRow, add to DataTable
dr = dt.NewRow();
dr["NAME"] = found.DisplayName;
if (props != null && props.Count > 0)
{
userId = GetUserIdFromPrincipal(found);
// Get other properties
string[] userProps = GetUserProperties(userId);
foreach (string s in props)
{
if (s == "USERNAME")
dr["USERNAME"] = userId;
if (s == "MIDDLE_NAME")
dr["MIDDLE_NAME"] = userProps[3];
if (s == "MIDDLE_INITIAL")
dr["MIDDLE_INITIAL"] = userProps[4];
if (s == "EMAIL")
dr["EMAIL"] = userProps[5];
if (s == "LOCATION")
dr["LOCATION"] = userProps[6];
if (s == "PHONE")
dr["PHONE"] = userProps[7];
if (s == "OFFICE")
dr["OFFICE"] = userProps[8];
if (s == "DEPARTMENT")
dr["DEPARTMENT"] = userProps[9];
}
}
dt.Rows.Add(dr);
}
}
}
}
return dt;
}
你可以这样调用这个函数:
string firstName = txtFirstName.Text;
string lastName = txtLastName.Text;
List<string> props = new List<string>();
props.Add("OFFICE");
props.Add("DEPARTMENT");
props.Add("LOCATION");
props.Add("USERNAME");
DataTable dt = GetUsersFromName(firstName, lastName, props);
DataTable 将填充这些列,NAME 列作为第一列,其中将包含来自 AD 的用户实际 .DisplayName。
注意:您必须引用System.DirectoryServices 和System.DirectoryServices.AccountManagement、System.Text.RegularExpressions、System.Data 才能使用所有这些。
HTH!
