Question

我尝试通过后面的代码增加实例数。

首先，我创建了一个.cer文件和.pfx文件，然后将其上传到.pfx到cloudservice证书和.cer到设置 - ＆gt;管理证书。

在我的代码中使用.cer文件后。我不太清楚这个uplod文件是真的吗？

这是我的代码：

string subscriptionId = "c034e905-......";
        string serviceName = "multitenant";
        string configFileName = "ServiceConfiguration.cscfg";
        string roleName = "Multi.Web";

        XNamespace xs = "http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration";
        XDocument configDocument = XDocument.Parse(String.Join("", File.ReadAllLines(Path.GetFullPath(configFileName))));
        XAttribute instanceCountAttribute = configDocument.Element(xs + "ServiceConfiguration")
                                                            .Elements(xs + "Role")
                                                            .Where(xRole => xRole.Attribute("name").Value == roleName).SingleOrDefault()
                                                            .Element(xs + "Instances")
                                                            .Attribute("count");

        int currentInstanceCount = int.Parse(instanceCountAttribute.Value);

我正在检查我的VM中的一些字段，并且我会增加我的currentInstanceCount。

double processorTotal = Convert.ToDouble(performanceCounter.CounterValue);

            instanceCountAttribute.Value = (currentInstanceCount + 1).ToString();

            var serviceManagment = ServiceManagementHelper.CreateServiceManagementChannel("WindowsAzureEndPoint",
                new X509Certificate2("multitenant.cer"));
            var changeConfigInput = new ChangeConfigurationInput();
            changeConfigInput.Configuration = ServiceManagementHelper.EncodeToBase64String(configDocument.ToString());
            try
            {
                serviceManagment.ChangeConfigurationBySlot(subscriptionId, serviceName, "Production", changeConfigInput);
            }
            catch (WebException e) 
            { 
                throw new Exception(new StreamReader(e.Response.GetResponseStream()).ReadToEnd()); 
            }

ChangeConfigurationBySlot方法抛出异常：

远程服务器返回了意外响应：（400）错误请求。

我哪里错了？我无法理解。它是关于方法参数还是错误的上传证书？

你有任何估计吗？

感谢。

我解决了我的问题。

这不是认证。首先我获得生产配置文件，然后更改它的当前实例数并重新部署。

以下是代码：

var deployment = managementClient.GetDeploymentBySlot（subscriptionId，serviceName，“Production”）;

        string configurationXml = ServiceManagementHelper.DecodeFromBase64String(deployment.Configuration);
        serviceConfiguration = XDocument.Parse(configurationXml);

        XNamespace xs = "http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration";
        instanceCountAttribute = serviceConfiguration.Element(xs + "ServiceConfiguration")
                                                            .Elements(xs + "Role")
                                                            .Where(xRole => xRole.Attribute("name").Value == roleName).SingleOrDefault()
                                                            .Element(xs + "Instances")
                                                            .Attribute("count");
        currentInstanceCount = int.Parse(instanceCountAttribute.Value);
