Ton*_*uca 4 .net c# windows digital-signature
我正在使用C#.NET构建一个应用程序(win form)来进行文档签名.我在签名时遇到错误.当我在某些计算机(Windows 7,Windows 10,而不是Windows Server)上签署文档时,我收到一个错误:"未定义的密钥集".那么,有人可以教程或建议我如何解决这个问题？非常感谢!这是我的代码:
// get certficate
public X509Certificate2 LoadCertificateFromWindowsStore()
{
X509Store x509Store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
try
{
x509Store.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly);
X509Certificate2Collection numberCerts = (X509Certificate2Collection)x509Store.Certificates;
X509Certificate2Enumerator certEnumerator;
if (numberCerts.Count == 1)
{
certEnumerator = numberCerts.GetEnumerator();
while (certEnumerator.MoveNext())
return certEnumerator.Current;
return null;
}
else if (numberCerts.Count > 1)
{
X509Certificate2Collection chooseCert = X509Certificate2UI.SelectFromCollection(numberCerts,
"Certificates List", "Choose your certificate", X509SelectionFlag.SingleSelection);
if (chooseCert.Count == 1)
return chooseCert[0];
else
return null;
}
else
return null;
}
catch (CryptographicException e)
{
Console.WriteLine(e.Message);
}
finally
{
x509Store.Close();
}
return null;
}
// using the cert to sign
var cert = LoadCertificateFromWindowsStore();
if (cert.HasPrivateKey) // WORKS!!!
{
signedXml.SigningKey = cert.PrivateKey; // THROW "keyset does not exist" EXCEPTION

我已经解决了这个错误.这很容易.您选择x86的"平台目标".
