X509Store.Open(OpenFlags) 方法

定义

命名空间:

System.Security.Cryptography.X509Certificates

程序集:

netstandard.dll, System.Security.Cryptography.dll

Source:

X509Store.cs

根据 OpenFlags 标志设置，打开 X.509 证书存储或创建一个新存储。

C#

public void Open(System.Security.Cryptography.X509Certificates.OpenFlags flags);

参数

flags

OpenFlags

一个枚举值的按位组合，它指定 X.509 证书存储的打开方式。

例外

CryptographicException

无法按要求打开存储。

SecurityException

调用方没有所要求的权限。

ArgumentException

此存储包含无效值。

示例

下面的代码示例打开 X.509 证书存储，添加和删除证书，然后关闭存储。 它假定你有三个证书要添加到本地存储以及从本地存储中删除。

C#

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

public class X509store2
{
    public static void Main (string[] args)
    {
        //Create new X509 store called teststore from the local certificate store.
        X509Store store = new X509Store ("teststore", StoreLocation.CurrentUser);
        store.Open (OpenFlags.ReadWrite);
        X509Certificate2 certificate = new X509Certificate2 ();

        //Create certificates from certificate files.
        //You must put in a valid path to three certificates in the following constructors.
        X509Certificate2 certificate1 = new X509Certificate2 ("c:\\mycerts\\*****.cer");
        X509Certificate2 certificate2 = new X509Certificate2 ("c:\\mycerts\\*****.cer");
        X509Certificate2 certificate5 = new X509Certificate2 ("c:\\mycerts\\*****.cer");

        //Create a collection and add two of the certificates.
        X509Certificate2Collection collection = new X509Certificate2Collection ();
        collection.Add (certificate2);
        collection.Add (certificate5);

        //Add certificates to the store.
        store.Add (certificate1);
        store.AddRange (collection);

        X509Certificate2Collection storecollection = (X509Certificate2Collection)store.Certificates;
        Console.WriteLine ("Store name: {0}", store.Name);
        Console.WriteLine ("Store location: {0}", store.Location);
        foreach (X509Certificate2 x509 in storecollection)
        {
            Console.WriteLine("certificate name: {0}",x509.Subject);
        }

        //Remove a certificate.
        store.Remove (certificate1);
        X509Certificate2Collection storecollection2 = (X509Certificate2Collection)store.Certificates;
        Console.WriteLine ("{1}Store name: {0}", store.Name, Environment.NewLine);
        foreach (X509Certificate2 x509 in storecollection2)
        {
            Console.WriteLine ("certificate name: {0}", x509.Subject);
        }

        //Remove a range of certificates.
        store.RemoveRange (collection);
        X509Certificate2Collection storecollection3 = (X509Certificate2Collection)store.Certificates;
        Console.WriteLine ("{1}Store name: {0}", store.Name, Environment.NewLine);
        if (storecollection3.Count == 0)
        {
            Console.WriteLine ("Store contains no certificates.");
        }
        else
        {
            foreach (X509Certificate2 x509 in storecollection3)
            {
                Console.WriteLine ("certificate name: {0}", x509.Subject);
            }
        }

        //Close the store.
        store.Close ();
    }	
}

注解

使用此方法打开现有的 X.509 存储。 请注意，必须具有由 StorePermissionFlags指定的其他权限才能枚举存储中的证书。 可以通过将不存在的存储名称传递给类构造函数，然后使用除 之外OpenExistingOnly的任何OpenFlags标志来创建新存储。
