X509Chain.ChainElements Property

Definition

Namespace:

System.Security.Cryptography.X509Certificates

Assemblies:

netstandard.dll, System.Security.Cryptography.dll

Source:

X509Chain.cs

Gets a collection of X509ChainElement objects.

C#

public System.Security.Cryptography.X509Certificates.X509ChainElementCollection ChainElements { get; }

Property Value

X509ChainElementCollection

An X509ChainElementCollection object.

Examples

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.

C#

    //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();

Remarks

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.
