hi,

this might help:

// user store is default store
StoreLocation location = StoreLocation.CurrentUser;

// open store
X509Store store = new X509Store(StoreName.My, location);
store.Open(OpenFlags.ReadOnly);

// select certificate
X509Certificate2Collection col = X509Certificate2UI.SelectFromCollection(
store.Certificates,
"www.leastprivilege.com",
"Select a Certificate",
X509SelectionFlag.SingleSelection);

store.Close();

if (col.Count != 1)
return;

// get path and filename of private key containers
string keyfileName = GetKeyFileName(col[0]);



private static string GetKeyFileName(X509Certificate2 cert)
{
string filename = null;

if (cert.PrivateKey != null)
{
RSACryptoServiceProvider provider = cert.PrivateKey as RSACryptoServiceProvider;
filename = provider.CspKeyContainerInfo.UniqueKeyContainerName;
}
return filename;
}

hi~ I build a CA based windows server 2003,and the aim of my project is to let users to request Certificate from this CA, and then users use their Certificate to sign the files that they want to send to others.The langusge i use is c#,and the project is based on b/s.
My problem is :if users ues the Certificate to fufill DigitalSignature,they must get the Privatekey of the Certificate,but the project is based on b/s,it seems the program can not access to the Client's Certificate-Store,Because when i use
//*********************************//
X509Store storeCertificates = new X509Store(StoreName.My, StoreLocation.CurrentUser);
int a =storeCertificates.count;
response.write(a);
//**********************************//
the result is a=0,but there are 3 Certificates in Certificate-store.And when i try these codes in Console,the result is correct(a=3),why? (Dose WebForm don't have purview to access the store of Certificate on the Client-PC?)

Please Help me~my email[email protected] ,thanks~
