X509Chain.ChainElements Property

Gets a collection of X509ChainElement objects.

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

public X509ChainElementCollection ChainElements { get; }
/** @property */
public X509ChainElementCollection get_ChainElements ()

public function get ChainElements () : X509ChainElementCollection

Not applicable.

Property Value

An X509ChainElementCollection object.

Each X509ChainElement object is a representation of an element in the chain that was built during a call to the Build method.

A chain element consists of an X509Certificate2 object, an X509ChainStatus structure, and an extra information string (available only on Windows XP platforms).

The following code example opens the current user's personal certificate store, allows you to select a certificate, then writes certificate and certificate chain information to the console. The output depends on the certificate you select.

//Output chain element information.
Console.WriteLine ("Chain Element Information");
Console.WriteLine ("Number of chain elements: {0}", ch.ChainElements.Count);
Console.WriteLine ("Chain elements synchronized? {0} {1}", ch.ChainElements.IsSynchronized, Environment.NewLine);
    
foreach (X509ChainElement element in ch.ChainElements)
{
    Console.WriteLine ("Element issuer name: {0}", element.Certificate.Issuer);
    Console.WriteLine ("Element certificate valid until: {0}", element.Certificate.NotAfter);
    Console.WriteLine ("Element certificate is valid: {0}", element.Certificate.Verify ());
    Console.WriteLine ("Element error status length: {0}", element.ChainElementStatus.Length);
    Console.WriteLine ("Element information: {0}", element.Information);
    Console.WriteLine ("Number of element extensions: {0}{1}", element.Certificate.Extensions.Count, Environment.NewLine);

    if (ch.ChainStatus.Length > 1)
    {
        for (int index = 0; index < element.ChainElementStatus.Length; index++)
        {
            Console.WriteLine (element.ChainElementStatus[index].Status);
            Console.WriteLine (element.ChainElementStatus[index].StatusInformation);
        }
    }
}
store.Close();
