我想查詢一個Azure表存儲。對於我使用下面的兩種方法:爲什麼我在查詢TableServiceContext時收到MissingMethodException?
TableServiceContext:使用上述方法
public IQueryable<T> QueryEntities<T>(string tableName) where T : TableServiceEntity
{
this.ResolveType = (unused) => typeof(T);
return this.CreateQuery<T>(tableName);
}
代碼:
CloudStorageAccount account = AzureConnector.GetCloudStorageAccount(AppSettingsVariables.TableStorageConnection);
AzureTableStorageContext context = new AzureTableStorageContext(account.TableEndpoint.ToString(), account.Credentials);
// Checks if the setting already exists in the Azure table storage. Returns null if not exists.
var existsQuery = from e in context.QueryEntities<ServiceSettingEntity>(TableName)
where e.ServiceName.Equals(this.ServiceName) && e.SettingName.Equals(settingName)
select e;
ServiceSettingEntity existingSettginEntity = existsQuery.FirstOrDefault();
上述LINQ查詢生成以下請求URL:
http://127.0.0.1:10002/devstoreaccount1/PublicSpaceNotificationSettingsTable()?$filter=(ServiceName eq 'PublicSpaceNotification') and (SettingName eq 'expectiss')
該類中的代碼生成以下MissingMethodException:
- 我已經看過了表API支持LINQ Queries;
- 看着幾個正在使用的計算器解決方案;
- 上TableServiceContext試過IgnoreResourceNotFoundException(的QueryOperators usercomments);
- 打過電話第一或默認(的QueryOperators usercomments)之前與ToList LINQ查詢()轉換。
,但我不能得到這個工作。
這確實是個問題!謝謝! – Cees
