Assembly: System.Web.Services (in system.web.services.dll)
Property ValueAn X509CertificateCollection that represents the client certificates.
This property allows a client to pass one or more client certificates, also known as Authenticode X.509 v.3 certificates, when calling an XML Web service method. If the XML Web service method has been configured to use client certificates, a client certificate can be used as one mechanism for authenticating a client. For details on setting up client certificates, see the Internet Information Services (IIS) documentation.
The following code example demonstrates how to load in a client certificate from a file and then add it to the ClientCertificates property for calling an XML Web service method that uses client certificates for authentication.
// Create a new instance of a proxy class for the Bank XML Web service. BankSession bank = new BankSession(); // Load the client certificate from a file. X509Certificate x509 = X509Certificate.CreateFromCertFile(@"c:\user.cer"); // Add the client certificate to the ClientCertificates property of the proxy class. bank.ClientCertificates.Add(x509); // Communicate with the Deposit XML Web service method, // which requires authentication using client certificates. bank.Deposit(500);
