c# - 当前上下文中不存在名称“X509Certificate2UI”

Question

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

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;
    }
}

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

您需要在System.Security.dll项目中包含参考，因为它不包含在mscorlib程序集中，而是包含在程序集中System.Security 。
