求教这句代码的意思，急啊急~~
System.Net.ServicePointManager.ServerCertificateValidationCallback += (se, cert, chain, sslerror) =>
{
return true;
};
System.Net.ServicePointManager.ServerCertificateValidationCallback += new System.Net.Security.RemoteCertificateValidationCallback(ServerCertificateValidationCallback);
private bool ServerCertificateValidationCallback(object sender, System.Security.Cryptography.X509Certificates.X509Certificate certificate, System.Security.Cryptography.X509Certificates.X509Chain chain, System.Net.Security.SslPolicyErrors sslPolicyErrors)
{
return true;
}
System.Net.ServicePointManager.ServerCertificateValidationCallback = DirectCast([Delegate].Combine(System.Net.ServicePointManager.ServerCertificateValidationCallback, New System.Net.Security.RemoteCertificateValidationCallback(AddressOf ServerCertificateValidationCallback)), System.Net.Security.RemoteCertificateValidationCallback)
Private Function ServerCertificateValidationCallback(sender As Object, certificate As System.Security.Cryptography.X509Certificates.X509Certificate, chain As System.Security.Cryptography.X509Certificates.X509Chain, sslPolicyErrors As System.Net.Security.SslPolicyErrors) As Boolean
Return True
End Function
