如何为 Azure 计算的 C# 客户端指定筛选器？

Question

我正在尝试使用Microsoft.Azure.Management.Compute的ComputeManagementClient来查询资源SKU。但是我无法为过滤器参数提供正确的值。如果没有过滤器，响应会非常大，我想通过使用 resourceType = 虚拟机进行过滤来减少它。

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生成过滤器字符串：

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 仅支持按区域过滤。有关更多详细信息，请参阅反馈和文章
