Question

我正在开发一个Windows服务，它将调用Microsoft Azure Management Libraries来管理云服务。但在这样做的同时，我的程序没有返回用于管理云活动的凭据。当我在Console Application中测试相同的代码时，它每次都运行良好，但是当我将代码与Windows Services集成时，用于获取凭据的函数给出异常Index was out of range. Must be non-negative and less than the size of the >>collection. Parameter name: index。我不知道为什么这个代码在返回证书时行为不正确。但是由于类X509Certificate2Collection无法找到证书并返回集合而发生异常。因此我的代码失败了。我的问题是：

任何人都可以告诉我解决上述错误的可能解决方案是什么。



为什么在Windows服务中集成相同代码时，我的代码行为会有所不同？

//代码

internal class CertificateAuthenticationHelper
{
    internal static SubscriptionCloudCredentials GetCredentials(
        string subscrtionId,
        string thumbprint)
    {
        return new CertificateCloudCredentials(subscrtionId, GetCertificate(thumbprint));
    }

    private static X509Certificate2 GetCertificate(string thumbprint)
    {
        X509Store certStore = null;
        X509Certificate2Collection certCollection = null;
        X509Certificate2 certificate = null;

        // Open the certificate store for the current user.
        certStore = new X509Store(StoreName.My, StoreLocation.CurrentUser);
        //certStore = new X509Store(StoreName.Root, StoreLocation.LocalMachine);

        certStore.Open(OpenFlags.ReadOnly);

        // Find the certificate with the specified thumbprint.
        certCollection = certStore.Certificates.Find(
                             X509FindType.FindByThumbprint,
                             thumbprint,
                             false);
        certStore.Close();
        // A matching certificate was found.
// Here I am getting exception as my function is unable to find any matching certificate. 
//I checked my certCollection.Count which is 0 in Windows Service. But when I am debugging the same code in Console Application its returning 1. 
            certificate = certCollection[0];
            return certificate;
        }
    }

Answer 1

请将管理证书放在a b 1 22 2 23证书商店而不是LocalMachine商店，并相应更改代码，以便从CurrentUser商店阅读。

从错误消息中可以看出，您的Windows服务无法在LocalMachine商店中找到该证书。很可能是因为Windows服务在不同的用户环境下运行。
