c# - 名称 'X509Certificate2UI' 在当前上下文中不存在

Question

有人在 Asp Net MVC4 应用程序中使用 X509Certificate2UI 类有问题

using System.Security.Cryptography.X509Certificates;


private static X509Certificate2 PickCertificate(StoreLocation location, StoreName name)
{

    try
    {
        store.Open(OpenFlags.ReadOnly);
        //PROBLEM IS HERE
        X509Certificate2 cert = X509Certificate2UI.SelectFromCollection(store.Certificates, "Caption", "Message", X509SelectionFlag.SingleSelection)[0]; 
}
    catch (Exception)
    {               
        throw;
    }
}

它提示当前上下文中没有“X509Certificate2UI”名称不知道，因为该类在 System.Security.Cryptography.X509Certificates 中；

您需要在您的项目中包含对 System.Security.dll 的引用，因为它不包含在 mscorlib 程序集中，但在 System.Security 中组装。
