Namespace:   System.Security.Cryptography.X509Certificates
Assembly:  System (in System.dll)

public:
void RemoveRange(
	X509Certificate2Collection^ certificates
)

Parameters

certificates
Type: System.Security.Cryptography.X509Certificates::X509Certificate2Collection^

A range of certificates to remove.

Exception Condition
ArgumentNullException

certificates is null.

SecurityException

The caller does not have the required permission.

System_CAPS_importantImportant

This type implements the IDisposable interface. When you have finished using the type, you should dispose of it either directly or indirectly. To dispose of the type directly, call its Dispose method in a try/catch block. To dispose of it indirectly, use a language construct such as using (in C#) or Using (in Visual Basic). For more information, see the “Using an Object that Implements IDisposable” section in the IDisposable interface topic.

This method removes more than one certificate from an X.509 certificate store; if one certificate removal fails, the operation is reverted and no certificates are removed.

The following code example opens an X.509 certificate store, adds and deletes certificates, and then closes the store. It assumes that you have three certificates to add to and remove from a local store.

#using <System.dll>
#using <System.Security.dll>

using namespace System;
using namespace System::Security::Cryptography;
using namespace System::Security::Cryptography::X509Certificates;
using namespace System::IO;
int main()
{

   //Create new X509 store called teststore from the local certificate store.
   X509Store ^ store = gcnew X509Store( "teststore",StoreLocation::CurrentUser );
   store->Open( OpenFlags::ReadWrite );
   X509Certificate2 ^ certificate = gcnew X509Certificate2;

   //Create certificates from certificate files.
   //You must put in a valid path to three certificates in the following constructors.
   X509Certificate2 ^ certificate1 = gcnew X509Certificate2( "c:\\mycerts\\*****.cer" );
   X509Certificate2 ^ certificate2 = gcnew X509Certificate2( "c:\\mycerts\\*****.cer" );
   X509Certificate2 ^ certificate5 = gcnew X509Certificate2( "c:\\mycerts\\*****.cer" );

   //Create a collection and add two of the certificates.
   X509Certificate2Collection ^ collection = gcnew X509Certificate2Collection;
   collection->Add( certificate2 );
   collection->Add( certificate5 );

   //Add certificates to the store.
   store->Add( certificate1 );
   store->AddRange( collection );
   X509Certificate2Collection ^ storecollection = dynamic_cast<X509Certificate2Collection^>(store->Certificates);
   Console::WriteLine( "Store name: {0}", store->Name );
   Console::WriteLine( "Store location: {0}", store->Location );
   System::Collections::IEnumerator^ myEnum = storecollection->GetEnumerator();
   while ( myEnum->MoveNext() )

      Console::WriteLine( "certificate name: {0}", x509->Subject );
   }


   //Remove a certificate.
   store->Remove( certificate1 );
   X509Certificate2Collection ^ storecollection2 = dynamic_cast<X509Certificate2Collection^>(store->Certificates);
   Console::WriteLine( "{1}Store name: {0}", store->Name, Environment::NewLine );
   System::Collections::IEnumerator^ myEnum1 = storecollection2->GetEnumerator();
   while ( myEnum1->MoveNext() )

      Console::WriteLine( "certificate name: {0}", x509->Subject );

   //Remove a range of certificates.
   store->RemoveRange( collection );
   X509Certificate2Collection ^ storecollection3 = dynamic_cast<X509Certificate2Collection^>(store->Certificates);
   Console::WriteLine( "{1}Store name: {0}", store->Name, Environment::NewLine );
   if ( storecollection3->Count == 0 )
   {
      Console::WriteLine( "Store contains no certificates." );
   }
   else
   {
      System::Collections::IEnumerator^ myEnum2 = storecollection3->GetEnumerator();
      while ( myEnum2->MoveNext() )
      {
         X509Certificate2 ^ x509 = safe_cast<X509Certificate2 ^>(myEnum2->Current);
         Console::WriteLine( "certificate name: {0}", x509->Subject );
      }

   //Close the store.
   store->Close();
