属性值

X509Certificate2Collection

证书集合。

示例

本部分包含两个示例。第一个示例演示如何打开标准 X.509 存储并列出每个存储中的证书数。

第二个示例演示如何添加和删除单个证书和证书范围。

示例 1

此示例尝试打开当前计算机上的每个标准位置中的每个标准存储。它打印一个摘要，显示每个存储是否存在，如果存在，则显示其包含的证书数。

该示例为标准名称和标准位置的每个组合创建一个 X509Store 对象。它使用标志调用 Open 方法 OpenFlags.OpenExistingOnly ，该方法仅在物理存储已存在时才打开。如果物理存储存在，则本示例使用 Name、 Location和 Certificates 属性来显示存储中的证书数。

using System;
using System.Security.Cryptography;
using System.Security.Cryptography.X509Certificates;

public class Example
{
    static void Main()
    {
        Console.WriteLine("\r\nExists Certs Name and Location");
        Console.WriteLine("------ ----- -------------------------");

        foreach (StoreLocation storeLocation in (StoreLocation[])
            Enum.GetValues(typeof(StoreLocation)))
        {
            foreach (StoreName storeName in (StoreName[])
                Enum.GetValues(typeof(StoreName)))
            {
                X509Store store = new X509Store(storeName, storeLocation);

                try
                {
                    store.Open(OpenFlags.OpenExistingOnly);

                    Console.WriteLine("Yes    {0,4}  {1}, {2}",
                        store.Certificates.Count, store.Name, store.Location);
                }
                catch (CryptographicException)
                {
                    Console.WriteLine("No           {0}, {1}",
                        store.Name, store.Location);
                }
            }
            Console.WriteLine();
        }
    }
}

注解

此方法返回 X.509 证书存储的快照。请注意，对存储执行的后续 Add 或 Remove 操作不会对返回的集合产生任何影响。每次调用属性时都会重新计算此快照，因此不建议在迭代函数中使用此属性。
