Question

所以问题是：我有一个类似40个属性的实体（所有在代码中都正确定义为“public String PropertyName {get; set;}”。当我插入新实体时，大多数属性都被存储，但其中一些不是。

代码如下：

public class PostTableEntity : TableEntity
{
    #region Fields
    #endregion

    #region Properties
    public Guid CreatorId { get; set; }
    public String HtmlText { get; set; }
    public String SubjectIds { get; set; }
    public String QuoteString { get; set; }
    public double GeoLat { get; set; }
    public double GeoLong { get; set; }
    public String GeoPlace { get; set; }
    public Int32 TotalSmiles { get; set; }
    public DateTime DateUTC { get; set; }
    public Guid? EventId { get; set; }
    public string EventName { get; set; }
    public String ExcludedUsers { get; set; }
    public String Comment00_Text { get; set; }
    public Guid Comment00_UserId { get; set; }
    public Guid Comment00_CommentId { get; set; }
    {...} //Some more props - no more than 30 in total        
    public String VeryImportantData { get; set; }
    #endregion

    #region Constructors
    public PostTableEntity()
    {

    }

    public PostTableEntity(String partitionKey, String rowKey, Guid creatorId, DateTime dateUTC, String htmlText)
        : base(partitionKey, rowKey)
    {
        this.CreatorId = creatorId;
        this.HtmlText = htmlText;
        this.DateUTC = dateUTC;
    }
    #endregion

    #region Methods
    public void SetSubjectIdsList(List<Guid> subjectIds)
    {
        if (subjectIds != null)
        {
            this.SubjectIds = String.Join(";", subjectIds);
        }
        else
        {
            this.SubjectIds = "";
        }
    }
    #endregion
}

...然后有一个派生类：

public class ImagePostTableEntity : PostTableEntity
{
    #region Fields
    #endregion

    #region Properties
    public String StorageAccountName { get; set; }
    public String StorageContainerName { get; set; }
    public String BlobName_Original { get; set; }
    public String BlobName_Large { get; set; }
    public String BlobName_Medium { get; set; }
    public String BlobName_Small { get; set; }      
    #endregion

    #region Constructors
    public ImagePostTableEntity()
    {

    }

    public ImagePostTableEntity(String partitionKey, String rowKey, Guid creatorId, DateTime date, String htmlText, List<Guid> subjectIds, String storageAccountName, String storageContainerName, String blobName_Original, String blobName_Large, String blobName_Medium, String blobName_Small)
        : base(partitionKey, rowKey, creatorId, date, htmlText)
    {            
        this.StorageAccountName = storageAccountName;
        this.StorageContainerName = storageContainerName;            

        this.BlobName_Original = blobName_Original;
        this.BlobName_Large = blobName_Large;
        this.BlobName_Medium = blobName_Medium;
        this.BlobName_Small = blobName_Small;

        this.SetSubjectIdsList(subjectIds);
    }
}

所以我这样称之为InsertOperation（我认为没什么特别的）：

 ImagePostTableEntity newPost = new ImagePostTableEntity(streamId.ToString(), newPostId.ToString(), creatorId, date, htmlText, subjectIds, storageAccountName, storageContainerName, blobName_Original, blobName_Large, blobName_Medium, blobName_Small); //This construcotr calls inner method: SetSubjectIdsList(subjectIds);
            newPost.TotalComments = 0;
            newPost.VeryImportantData = "That very important string";
            TableOperation insertOperation = TableOperation.Insert(newPost);

执行此操作后，实体存在于表存储中，但不存储某些属性。具体而言，不存储“SubjectIds”和“VeryImportantData”。它们不为空，它们有一些值（双重检查;））

除了Emily提到的没有执行方法的内容之外，我还没有看到为subjectIds设置值的代码。艾米丽提出的另一个好处是，你如何验证该实体没有这些属性？

尝试使用fiddler确保确实发送了某些内容。

我很确定您之前已经看过this guidance，但请再次检查以确保您没有遗漏任何内容。

请记住，在执行Insert操作时，如果该表中已存在具有相同PK和RK的实体，则不会插入实体。 InsertOrReplace操作将允许您执行此操作。

Azure存储表 - 并非所有来自TableEntity的属性都在InsertOperation之后存储
