  This method verifies all signatures, including countersignatures, on the CMS/PKCS #7 message. If there are signed attributes included with the message, these attributes are also verified. If the option is chosen to validate certificates, the entire included portion of the certificate chain is validated.  
   
  This method throws an exception if the verification of a digital signature fails or any validation requirements are not met.

- The following example shows the placement of <xref:System.Security.Cryptography.Pkcs.SignedCms.CheckSignature%28System.Security.Cryptography.X509Certificates.X509Certificate2Collection%2CSystem.Boolean%29> among the steps necessary to verify the signatures on a <xref:System.Security.Cryptography.Pkcs.SignedCms> message. In this example, the message content is not detached, so the message content is included in the <xref:System.Security.Cryptography.Pkcs.SignedCms> message.
