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
)

Parameters

certificates
Type: System.Security.Cryptography.X509Certificates.X509Certificate2Collection
The collection of certificates to add.

ExceptionCondition
ArgumentNullException

certificates is null.

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.


using System;
using System.Security.Cryptography;
using System.Security.Cryptography.X509Certificates;
using System.IO;

public class X509store2
{
	public static void Main (string[] args)
	{
		//Create new X509 store called teststore from the local certificate store.
		X509Store store = new X509Store ("teststore", StoreLocation.CurrentUser);
		store.Open (OpenFlags.ReadWrite);
		X509Certificate2 certificate = new X509Certificate2 ();

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

		//Create a collection and add two of the certificates.
		X509Certificate2Collection collection = new X509Certificate2Collection ();
		collection.Add (certificate2);
		collection.Add (certificate5);

		//Add certificates to the store.
		store.Add (certificate1);
		store.AddRange (collection);

		X509Certificate2Collection storecollection = (X509Certificate2Collection)store.Certificates;
		Console.WriteLine ("Store name: {0}", store.Name);
		Console.WriteLine ("Store location: {0}", store.Location);
		foreach (X509Certificate2 x509 in storecollection)
		{
			Console.WriteLine("certificate name: {0}",x509.Subject);
		}

		//Remove a certificate.
		store.Remove (certificate1);
		X509Certificate2Collection storecollection2 = (X509Certificate2Collection)store.Certificates;
		Console.WriteLine ("{1}Store name: {0}", store.Name, Environment.NewLine);
		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)
		{
			Console.WriteLine ("Store contains no certificates.");
		}
		else
		{
			foreach (X509Certificate2 x509 in storecollection3)
			{
				Console.WriteLine ("certificate name: {0}", x509.Subject);
			}
		}

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