c# - DocumentClient CreateDocumentQuery 异步

Question

为什么没有 CreateDocumentQuery 的异步版本？

这个方法例如可以是异步的:

    using (var client = new DocumentClient(new Uri(endpointUrl), authorizationKey, _connectionPolicy))
    {
        List<Property> propertiesOfUser =
            client.CreateDocumentQuery<Property>(_collectionLink)
                .Where(p => p.OwnerId == userGuid)
                .ToList();

        return propertiesOfUser;
    }

很好的查询，

只需尝试以下代码以异步方式使用它。

DocumentQueryable.CreateDocumentQuery 方法为集合下的文档创建查询。

 // Query asychronously.
using (var client = new DocumentClient(new Uri(endpointUrl), authorizationKey, _connectionPolicy))
{
     var propertiesOfUser =
        client.CreateDocumentQuery<Property>(_collectionLink)
            .Where(p => p.OwnerId == userGuid)
            .AsDocumentQuery(); // Replaced with ToList()


while (propertiesOfUser.HasMoreResults) 
{
    foreach(Property p in await propertiesOfUser.ExecuteNextAsync<Property>())
     {
         // Iterate through Property to have List or any other operations
     }
}


}
