Question

我正在使用以下代码从asp.net webapp中检索我的电脑中的所有证书。证书集合是空的，我不明白为什么。

我尝试冒充我自己的用户帐户，但我也没有成功。我做错了什么？

var store = new X509Store(StoreLocation.CurrentUser); //StoreLocation.LocalMachine fails too
var certificates = store.Certificates;
foreach (var certificate in certificates)
{
    var friendlyName = certificate.FriendlyName;
    Console.WriteLine(friendlyName);
}

//original problem: fetch a single certificate by its subject name
X509Certificate2 clientCertificate = CertificateUtility.GetCertificate(StoreName.My, StoreLocation.CurrentUser,  "CN=mypc.domainname"); //returns null :(

Answer 1

将这行代码添加到第二行，看看它是如何工作的：

store.Open(OpenFlags.ReadOnly);

然后在底部：）：

store.Close();

Answer 2

一体化......

我有一个带https的apache服务器（xamp）。我通过https和c＃访问（vs2010）到PHP上传页面

例如，从个人文件夹证书中安装证书。
要查看证书运行“certmgr.msc”，至少在win7中

列出个人证书

var store = new X509Store(StoreLocation.CurrentUser); 

store.Open(OpenFlags.ReadOnly); 

var certificates = store.Certificates;
foreach (var certificate in certificates)
{
    var friendlyName = certificate.FriendlyName;
    var xname = certificate.GetName(); //obsolete
    Console.WriteLine(friendlyName);
}

store.Close();

查找特定证书

string certificateName = "CN=localhost"; //name found in the var xname
X509Store storex = new X509Store(StoreName.My, StoreLocation.CurrentUser);
                    storex.Open(OpenFlags.ReadOnly);
X509Certificate2Collection certificatesx =
            storex.Certificates.Find(X509FindType.FindBySubjectName, 
            certificateName,
            true);

X509Certificate certificatex = certificates[0];

storex.Close();

Answer 3

我可以通过......找到证书。

var certificateStore = new X509Store(StoreName.TrustedPeople, StoreLocation.LocalMachine);

certificateStore.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly);

var certificateCollection = certificateStore.Certificates.Find(X509FindType.FindBySubjectName, "mycert.me.com",false);

certificateStore.Close();

var certificate = certificateCollection[0];

certificateCollection将拥有我关心的证书......如果它只是一个，那么我会在集合中获得第一个元素。

Answer 4

查看证书存储区（mmc / add / certificate管理单元/我的用户帐户/证书 - 当前用户/个人/证书）以查看主题名称以确保“CN = mypc.domainname”实际上是什么证书。

"CN=mypc.domainname"

VS

"CN = mypc.domainname"

...等
