如何將所有對象屬性傳遞給WCF服務？

Question

我必須承認我對WCF更復雜的能力的把握讓我感到困惑，所以這可能是一個愚蠢的問題。我有一組類，像這樣：

[DataContract] 
public class InvoiceItem 
{ 
    #region Properties 
    public bool Submittable { get; set; } 
    public string InvoiceID { get; set; } 
    public string VendorId { get; set; } 
    public string BatchId { get; set; } 
    /// <summary> 
    /// Marked as "Not Used", but explicitly set to 176. 
    /// </summary> 
    [ForFutureUse("Not used at this time", "176")] 
    public string LocationCode { get; set; } 
    public string VendorDocNumber { get; set; } 
    public string Description { get; set; } 
    public DateTime DocumentDate { get; set; } 
    public decimal PurchaseInvoiceAmount { get; set; } 
    public decimal TaxForm1099Amount { get; set; } 
    [ForFutureUse("Not used at this time")] 
    public string PayNumber { get; set; } 
    /// <summary> 
    /// Not marked as "Not Used", but not used. 
    /// </summary> 
    public string PaymentTerms { get; set; } 
    [ForFutureUse("Not used at this time")] 
    public decimal PurchaseAmount { get; set; } 
    [ForFutureUse("Not used at this time")] 
    public DateTime PayDate { get; set; } 
    [ForFutureUse("Not used at this time")] 
    public string DocumentID { get; set; } 
    public string DocumentType { get; set; } 
    public IList<InvoiceDetail> InvoiceDetails { get; set; } 
    /// <summary> 
    /// If the invoice is marked as not submittable, this should be set to explain why. 
    /// </summary> 
    public TroubleClasses TroubleClass { get; set; } 
    #endregion 

    #region Constructors 
    public InvoiceItem() { } 
    public InvoiceItem(XmlNode invoiceNode) 
    { 
     //collect the invoice data 
     this.InvoiceID = invoiceNode.SelectSingleNode("INVOICEHEADER/VOUCHERID").InnerText.Trim(); 
     this.VendorId = invoiceNode.SelectSingleNode("INVOICEHEADER/SUPPLIER.CODE").InnerText.Trim(); 
     this.BatchId = string.Format("D{0}", DateTime.UtcNow.ToShortDateString()); 
     this.LocationCode = "176"; 
     this.VendorDocNumber = invoiceNode.SelectSingleNode("INVOICEHEADER/SUPPLIERREF").InnerText.Trim(); 
     this.Description = invoiceNode.SelectSingleNode("INVOICEHEADER/ARRIVAL").InnerText.TrimEnd() + " " + invoiceNode.SelectSingleNode("ACCOUNTLINES/ACCOUNTLINE/DIMENSION.D2.CODE").InnerText.TrimEnd(); 
     this.DocumentDate = DateTime.ParseExact(
      invoiceNode.SelectSingleNode("INVOICEHEADER/INVOICEDATE").InnerText.Trim(), 
      "YYYYMMdd", CultureInfo.InvariantCulture); 
     this.PurchaseInvoiceAmount = Math.Abs(decimal.Parse(invoiceNode.SelectSingleNode("INVOICEHEADER/AMOUNT").InnerText.Trim())); 
     this.TaxForm1099Amount = decimal.Parse(invoiceNode.SelectSingleNode("INVOICEHEADER/SUPPLIER.CODE").InnerText.Trim()); 
     this.PayNumber = string.Empty; 
     this.PaymentTerms = string.Empty; 
     this.PurchaseAmount = 0.0M; 
     this.PayDate = DateTime.MinValue; 
     this.DocumentID = string.Empty; 
     this.DocumentType = invoiceNode.SelectSingleNode("INVOICEHEADER/CATEGORY").InnerText.Trim(); 

     //collect the detail data 
     this.InvoiceDetails = new List<InvoiceDetail>(); 
     var rowNumber = 0; 
     foreach (XmlNode detail in invoiceNode.SelectNodes("ACCOUNTLINES/ACCOUNTLINE")) 
     { 
      var newDetail = new InvoiceDetail(detail, this); 
      newDetail.RowNumber = ++rowNumber; 
      this.InvoiceDetails.Add(newDetail); 
     } 
     //all done! 
    } 
    #endregion 
} 

[DataContract] 
public class InvoiceDetail 
{ 
    #region Properties 
    public string Account { get; set; } 
    /// <summary> 
    /// This number must be unique and sequential in a given invoice. 
    /// </summary> 
    public int RowNumber { get; set; } 
    /// <summary> 
    /// Always set to "6". 
    /// </summary> 
    public int PayType { get; set; } 
    public decimal Debit { get; set; } 
    public decimal Credit { get; set; } 
    #endregion 

    #region Constructors 
    public InvoiceDetail() { } 
    public InvoiceDetail(XmlNode line, InvoiceItem invoiceItem) 
    { 
     var amount = Math.Abs(decimal.Parse(line.SelectSingleNode("AMOUNT").InnerText.Trim())); 
     this.Account = string.Format("{0}-{1}-{2}-{3}-{4}", 
      line.SelectSingleNode("ACCOUNTLINK.CODE").InnerText.TrimEnd(), 
      line.SelectSingleNode("DIMENSION.D1.CODE").InnerText.TrimEnd(), 
      line.SelectSingleNode("DIMENSION.D2.CODE").InnerText.TrimEnd(), 
      line.SelectSingleNode("DIMENSION.D3.CODE").InnerText.TrimEnd(), 
      line.SelectSingleNode("DIMENSION.D4.CODE").InnerText.TrimEnd()); 
     switch (invoiceItem.DocumentType) 
     { 
      case "2": 
       this.Credit = amount; 
       this.Debit = 0M; 
       break; 
      default: 
       this.Credit = 0M; 
       this.Debit = amount; 
       break; 
     } 
     this.PayType = 6; //no idea what this is. 
    } 
    #endregion 
} 

我想通過發送WCF的Web服務這InvoiceItem對象。我希望在客戶端做這樣的事情：

var invoice = new InvoiceItem(someXmlNode); 
using (var WebService = new WCFWebServices.WCFWebService()) 
{ 
    WebService.SubmitPayableTransaction(invoice); 
} 

同樣我希望有在服務這樣的事情：

public class WCFWebService:IWCFWebService 
{ 
    public void SubmitPayableTransaction(InvoiceItem invoice) 
    { 
     ... 
    } 
} 

這顯然並非如此。即使我將InvoiceItem類移入其自己的庫中，並且兩個項目都引用它，客戶端也有一個非常不同的外觀對象作爲其Web服務定義的一部分，並且也有一個不同的名稱空間。

我該怎麼做？

你需要的數據成員屬性添加到所有你想傳達給客戶

但請記住你是不是堅持本身的對象，但定義數據傳遞對象的數據項的服務之間傳遞和客戶端
