Examples

The following Visual Basic .NET example creates a new DirectoryEntry object with the specified path, then creates a new entry in the container and saves it. It attempts to retrieve the newly created entry.

Try  
     Dim myEntry1 As DirectoryEntry  
     Dim myEntry2 As DirectoryEntry  
     Dim strPath As String = "LDAP://DC=fabrikam,DC=com"  

     ' Create a 'DirectoryEntry' object with the given path.  
     Dim myDE As New DirectoryEntry(strPath)  
     Dim myEntries As DirectoryEntries = myDE.Children  

     ' Create a new entry in the container.  
     myEntry1 = myEntries.Add("CN=Sample Entry", myDE.SchemaClassName)  
     ' Save changes in the 'Active Directory Domain Services' store.  
     myEntry1.CommitChanges()  

     ' Find a child in the 'DirectoryEntries' collection which has the   
     ' specified name and type.  
     myEntry2 = myEntries.Find("CN=Sample Entry", myDE.SchemaClassName)  
     Console.WriteLine(myEntry2.Name + " is found in container.")  

     Catch e As Exception  
          Console.WriteLine("The following exception was raised : {0}", e.Message.ToString())  
     End Try  

The following C# example shows how to create a new DirectoryEntry object with the specified path, then creates a new entry in the container and saves it. It attempts to retrieve the newly- created entry.

using System;  
using System.DirectoryServices;   

class MyClass1  
{  
   static void Main()  
   {  
      try  
      {          
         DirectoryEntry myEntry1;  
         DirectoryEntry myEntry2;  
         String strPath = "LDAP://DC=fabrikam,DC=com";  

         // Create a 'DirectoryEntry' object with the given path.  
         DirectoryEntry myDE = new DirectoryEntry(strPath);  
         DirectoryEntries myEntries = myDE.Children;  

         // Create a new entry in the container.  
         myEntry1 = myEntries.Add("CN=Sample Entry",myDE.SchemaClassName);  
         // Save changes in the 'Active Directory Domain Services' store.  
         myEntry1.CommitChanges();  

         // Find a child in the 'DirectoryEntries' collection which has the   
         // specified name and type.  
         myEntry2 = myEntries.Find("CN=Sample Entry",myDE.SchemaClassName);  
         Console.WriteLine (myEntry2.Name + " is found in container.");  

      }  
      catch(Exception e)  
      {  
         Console.WriteLine("The following exception was raised : {0}",e.Message);  
      }  
   }  
}  

The following C++ example creates a new DirectoryEntry object with the specified path, then creates a new entry in the container and saves it. It attempts to retrieve the new entry.

#using <mscorlib.dll>  
#using <System.dll>  
#using <System.Directoryservices.dll>  

using namespace System;  
using namespace System::DirectoryServices;   

int main() {  
    try {          
        DirectoryEntry* myEntry1;  
        DirectoryEntry* myEntry2;  
        String* strPath = S"LDAP://DC=fabrikam,DC=com";  

        // Create a 'DirectoryEntry' object with the given path.  
        DirectoryEntry* myDE = new DirectoryEntry(strPath);  
        DirectoryEntries* myEntries = myDE->Children;  

        // Create a new entry in the container.  
        myEntry1 = myEntries->Add(S"CN=Sample Entry", myDE->SchemaClassName);  
        // Save changes in the 'Active Directory Domain Services' store.  
        myEntry1->CommitChanges();  

        // Find a child in the 'DirectoryEntries' collection which has the   
        // specified name and type.  
        myEntry2 = myEntries->Find(S"CN=Sample Entry", myDE->SchemaClassName);  
        Console::WriteLine ("{0} is found in container.", myEntry2->Name);  
    } catch(Exception* e) {  
        Console::WriteLine("The following exception was raised : {0}", e->Message);  
    }  
}
