X509Store.AddRange Method

Adds a collection of certificates to an X.509 certificate store.

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

public void AddRange (
	X509Certificate2Collection certificates
)
public void AddRange (
	X509Certificate2Collection certificates
)
public function AddRange (
	certificates : X509Certificate2Collection
)
Not applicable.

Parameters

certificates

An X509Certificate2Collection object.

Exception typeCondition

ArgumentNullException

certificates is a null reference (Nothing in Visual Basic).

SecurityException

The caller does not have the required permission.

This method adds more than one certificate to an X.509 certificate store; if one certificate addition fails, the operation is reverted and no certificates are added.

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.

		store.Open (OpenFlags.ReadWrite);
		X509Certificate2 certificate = new X509Certificate2 ();

		//Create certificates from certificate files.

		foreach (X509Certificate2 x509 in storecollection2)
		{
			Console.WriteLine ("certificate name: {0}", x509.Subject);
		}

		//Remove a range of certificates.
		store.RemoveRange (collection);
		X509Certificate2Collection storecollection3 = (X509Certificate2Collection)store.Certificates;
		Console.WriteLine ("{1}Store name: {0}", store.Name, Environment.NewLine);
		if (storecollection3.Count == 0)

		else
		{
			foreach (X509Certificate2 x509 in storecollection3)
			{
				Console.WriteLine ("certificate name: {0}", x509.Subject);
			}
		}

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