X509Certificate2-class problem

i have two machines machine1 and machine2. On one of those two machines (machine2) is my certificate store, the certificate store on machine1 is not allowed to be used. Further, i have do do some webservice-calls开发者_开发问答 from machine1 against an client-certificate-secured web-service. The certificate which i would like to add to the web-service-calls is stored in the certificate store on machine2 and is planned to be retrieved from machine2 over an internal web-service and then to be attached to my SoapHttpClientProtocol-instance on machine1, when machine1 is calling an external web-service.

I export the client-certificate on machine2 with sth like this: cert.Export(X509ContentType.SerializedCert)

..and give the base64Binary back to machine1 for further use.

Then it comes to the problem: If i create a new X509Certificate2 object from that byte-array (from the base64Binary) on machine1 and attach it to the SoapHttpClientProtocol it doesn´t work. But otherwise, if i create a new X509Certificate-object (no '2' !) from the byte-array and attach this to my SoapHttpClientProtocol, it works! The problem is that, if use the "older" class X509Certificate, then i have to install the client-certificate (including the private key) on machine1 also! And that makes no sense. Can someone help me and give me the right hint for this problem, please!

In general, you cannot do that. To use a certificate, you need to have its private key installed. Sounds like you aren't allowed to do that on machine #2.
