ServicePointManager.ServerCertificateValidationCallback

[C# Programming]

Dear Friends,

I stuck at a point, to download a file from HTTPS site.

I have a secured web site https/www.mySite.com/.
I havent any idea which Certificate that server is using.
I just want to down load a file from that site.

For that I have written the code:

private static bool ValidateRemoteCertificate(
object sender,
X509Certificate certificate,
X509Chain chain,
SslPolicyErrors policyErrors
)
{

if (policyErrors == SslPolicyErrors.None)
return true;
else
return false;


));

// // Do not allow this client to communicate with unauthenticated servers.
// return false;
// }


but it always shows the error "System.Net.Security.SslPolicyErrors.RemoteCertificateNameMismatch"

and if i forcefully return true it works fine...
what is proper solution??????


thnaks in advance
