如何为 Azure Compute 的 C# 客户端指定过滤器？

Question

我正在尝试使用 Microsoft.Azure.Management.Compute 的 ComputeManagementClient 来查询 ResourceSKUs。但我无法为过滤器参数提供正确的值。没有过滤器，响应非常大，我想通过使用 resourceType = virtualMachines 进行过滤来减少它。

更具体地说，这是我的代码：

ComputeManagementClient computeManagementClient = new ComputeManagementClient(credentials);
computeManagementClient.SubscriptionId = "**********";
string filter = "resourceType eq 'virtualMachines'";  // Doesn't work. All results are returned.
// string filter = "$filter=resourceType eq 'virtualMachines'";  // Doesn't work. All results are returned.
// string filter = "resourceType eq virtualMachines";  // Doesn't work. All results are returned.
// string filter = "resourceType eq 'Microsoft.Compute/virtualMachines'";  // Doesn't work. All results are returned.
// string filter = "resourceType = 'virtualMachines'";  // Doesn't work. All results are returned.
// string filter = "resourceType='virtualMachines'";  // Doesn't work. All results are returned.
IPage<ResourceSku> resourceSkus = await computeManagementClient.ResourceSkus.ListAsync(filter: filter);

我还尝试使用 OData.FilterString.Generate 来 generate 过滤字符串：

Expression<Func<ResourceSku, bool>> filterPredicate = x => x.ResourceType.Equals("virtualMachines", StringComparison.OrdinalIgnoreCase);
string filter = FilterString.Generate(filterPredicate);
IPage<ResourceSku> resourceSkus = await computeManagementClient.ResourceSkus.ListAsync(filter: filter);

知道正确的格式是什么吗？

根据我的研究，ResourceSkus API 仅支持按地区筛选。详情请参考feedback and the article
