当前上下文中不存在名称"X509Certificate2UI" [英] name 'X509Certificate2UI' does not exist in the current context

问题描述

在ASP.NET MVC4应用程序中使用X509Certificate2UI类是否有人遇到问题

Does anyone had problem using X509Certificate2UI class in an Asp Net MVC4 application

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 由于该类位于System.Security.Cryptography.X509Certificates;中，所以不知道；

It complains that there is no 'X509Certificate2UI' name in the current context No idea since the class is in System.Security.Cryptography.X509Certificates;

推荐答案

您需要在项目中包括对System.Security.dll的引用，因为它 不包含在mscorlib程序集中，但包含在System.Security中 组装.

You need to include reference for System.Security.dll into your project, since it is not included in the mscorlib assembly, but in the System.Security assembly.
