Question

我在从windows azure table storage回读时遇到了问题：

以下是我用来从表存储中检索UserEntity的代码：

TableServiceContext tableServiceContext = new TableServiceContext(storageAccount.TableEndpoint.AbsoluteUri, storageAccount.Credentials);
tableServiceContext.RetryPolicy = RetryPolicies.Retry(3, TimeSpan.FromSeconds(1));
user = (from g in tableServiceContext.CreateQuery<UserEntity>(PazoozaEnums.PazoozaTables.UsersUserFacebookActions.ToString())
        where g.PartitionKey.Equals(FacebookUserID) && g.Kind.Equals(PazoozaEnums.TableKinds.User.ToString())
        select g).AsTableServiceQuery().Execute().FirstOrDefault();

以下是存储在表存储中的用户实体。请注意，它实际上具有每个属性的值。但是返回的是null。或者JoinDate字段为1/1/0001，整数或长字段为0。我检查RowKey和PartitionKey，这些正确地作为实体的一部分返回，但其余的不是。任何人有任何想法，或在正确填充partitionkey和rowkey但其余字段不是之前遇到此问题？我在32位机器上使用nov 2011 azure sdk，c＃mvc3。

这是我的UserEntity类：

public class UserEntity : KindEntity, IUserEntity
{
    // PartitionKey = UserID
    // RowKey = (DateTime.MaxValue - DateTime.UtcNow).Ticks.ToString("d19") + Guid.NewGuid().ToString()

    public UserEntity() : this(null, null) { }
    public UserEntity(string partitionKey, string rowKey) : base(partitionKey, rowKey, PazoozaEnums.TableKinds.User.ToString()) { }

    public string Name { get; set; }
    public long PageID { get; set; }
    public int PageSize { get; set; }
    public int VideoPageSize { get; set; }
    public string EmailAddress { get; set; }
    public string AccessToken { get; set; }
    public string PageAccessToken { get; set; }
    public string OfflineAccessToken { get; set; }
    public string SmallPicture { get; set; }
    public string SmallPictureSquare { get; set; }
    public string ProfileLink { get; set; }
    public string AlternativeName { get; set; }
    public string AlternativeSmallPicture { get; set; }
    public string AlternativeSmallPictureSquare { get; set; }
    public string AlternativeProfileLink { get; set; }
    public DateTime JoinDate { get; set; }
}

如果您未在查询中指定RowKey，则可能存在正在返回的现有“空”行而不是您期望的行。
