DropDownにWindows認証済みのユーザーを設定しますか？

Question

私はこれについての私の検索で空手を思いついた。誰でも答えがありますか？ MVC3/C＃を使用しています。ありがとう。

これを行う1つの方法は、System.DirectoryServices.DirectorySearcherを使用して、アクティブディレクトリからのユーザーのリストを尋ねることです。

ここで我々が使用するクラスです。 FetchContacts静的メソッドを呼び出してユーザーを取得することができます。

using System; 
using System.Collections.Generic; 
using System.DirectoryServices; 

public class ActiveDirectorySystem 
{ 
    private const string PROPERTY_DISPLAY_NAME = "displayName"; 

    private static DirectorySearcher Initialize() 
    { 
     // Exceptions are handled by the caller 

     // Obtain the domain root entry 
     using (DirectoryEntry theRootEntry = new DirectoryEntry("LDAP://RootDSE")) 
     { 
      object theNamingContext = null; 
      string sNamingContext = null; 

      // Verify that we retrieved it correctly and raise an error if we did not 
      if (theRootEntry == null) 
      { 
       throw new Exception("A directory services entry for the LDAP RootDSE could not be created."); 
      } 

      // Get the root naming context 
      theNamingContext = theRootEntry.Properties["rootDomainNamingContext"].Value; 
      // Verify that we retrieved it correctly and raise an error if we did not 
      if ((theNamingContext == null) || (theNamingContext.ToString().Length == 0)) 
      { 
       throw new Exception("The root domain naming context property could not be retrieved from the LDAP directory services"); 
      } 
      else 
      { 
       sNamingContext = theNamingContext.ToString(); 
      } 

      // And create a new directory entry for the root naming context 
      using (DirectoryEntry theEntry = new DirectoryEntry("LDAP://" + sNamingContext)) 
      { 
       // Verify that we retrieved it correctly and raise an error if we did not 
       if (theEntry == null) 
       { 
        throw new Exception("A directory entry object could not be created for LDAP://" + sNamingContext); 
       } 

       // Now we configure what we are looking for from Active Directory 
       DirectorySearcher oSearcher = null; 

       // Start with a new searcher for the root domain 
       oSearcher = new DirectorySearcher(theEntry); 
       // Verify that we retrieved it correctly and raise an error if we did not 
       if (oSearcher == null) 
       { 
        throw new Exception("A directory searcher object could not be created for LDAP://" + sNamingContext); 
       } 

       // And the properties we want to retrieve 
       oSearcher.PropertiesToLoad.Add(PROPERTY_DISPLAY_NAME); 

       return oSearcher; 
      } 
     } 
    } 

    /// <summary> 
    /// This method retrieves the set of users from active directory that meet the criteria specified in filter. 
    /// </summary> 
    /// <param name="sFilter"></param> 
    /// <returns></returns> 
    /// <remarks></remarks> 
    public static List<string> FetchContacts(string sFilter = "") 
    { 
     // Exceptions are handled by the caller 

     using (DirectorySearcher oSearcher = Initialize()) 
     { 
      if (oSearcher != null) 
      { 
       List<string> cNames = new List<string>(); 

       // Specify what we are looking for, which is the account name of the specified user without any domain information 
       oSearcher.Filter = string.Format("(&(objectCategory=person)(objectClass=user){0})", sFilter); 

       // get all of the matching records 
       using (SearchResultCollection cResults = oSearcher.FindAll()) 
       { 
        if (cResults != null) 
        { 
         foreach (SearchResult theCurrentResult in cResults) 
         { 
          System.DirectoryServices.ResultPropertyCollection oProperties = null; 

          oProperties = theCurrentResult.Properties; 
          // First, verify that at least the display name is contained in the result 
          if (oProperties.Contains(PROPERTY_DISPLAY_NAME) && oProperties[PROPERTY_DISPLAY_NAME].Count > 0) 
          { 
           cNames.Add(oProperties[PROPERTY_DISPLAY_NAME][0].ToString()); 
          } 
         } 
        } 
       } 

       return cNames; 
      } 
     } 

     return null; 
    } 
}
