範例

本節包含兩個範例。第一個範例示範如何開啟標準 X.509 儲存庫，並列出每個儲存庫中的憑證數量。

第二個範例展示了如何新增或移除單一憑證及憑證範圍。

範例 1

此範例嘗試在當前電腦的每個標準位置開啟每個標準儲存裝置。它會列印一份摘要，顯示每家門市是否存在，以及如果存在，包含多少證書。

範例為每種標準名稱與標準位置的組合建立一個 X509Store 物件。它會用 flag Open 呼叫OpenFlags.OpenExistingOnly方法，只有在實體儲存庫已經存在時才會開啟。若實體儲存庫存在，範例會使用 Name、 Location及 Certificates 屬性來顯示儲存庫中的憑證數量。

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();
        }
    }
}

/* This example produces output similar to the following:

Exists Certs Name and Location
------ ----- -------------------------
Yes       1  AddressBook, CurrentUser
Yes      25  AuthRoot, CurrentUser
Yes     136  CA, CurrentUser

範例 2

此範例會開啟 X.509 憑證儲存，新增與刪除憑證，然後關閉該儲存。它假設你有三個憑證可以新增或移除在當地商店。

備註

用這個類別來處理 X.509 儲存裝置。

Important

從 .NET Framework 4.6 開始，這種介面類型實現了。IDisposable 當您完成使用這個物品後，應直接或間接地處理它。若要直接處置類型，請在 Disposetry/ 區塊中呼叫其 catch 方法。若要間接處置它，請使用語言建構，例如 using （C#）或 Using （在 Visual Basic 中）。如需詳細資訊，請參閱介面主題中的 <使用實作 IDisposable 的物件>一節。

對於針對 .NET Framework 4.5.2 及更早版本的應用程式，該X509Store類別不實作介面IDisposable，因此沒有方法。Dispose
