X509ChainElementCollection Class

Note: This class is new in the .NET Framework version 2.0.

Represents a collection of X509ChainElement objects. This class cannot be inherited.

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

public sealed class X509ChainElementCollection : ICollection, IEnumerable
public final class X509ChainElementCollection implements ICollection, IEnumerable
public final class X509ChainElementCollection implements ICollection, IEnumerable

An instance of this class is returned when the ChainElements property is called.

The following code example opens the current user's personal certificate store, allows the user to select a certificate, and 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();
