如何將附加到CRM標註中的表單上的字段？

我找不到任何關於此的信息。我有一個從表單觸發的CRM標註，我需要附加到其中一個字段;例如，該字段可能有「BH」之類的內容，並且我需要標註進行一些計算並更改字段，以便它讀取「BH002129」或其他內容，但無論我如何嘗試，結果都只是完全覆蓋該字段（所以在這種情況下，它只會說「002129」）。我似乎無法得到它追加，我也無法弄清楚如何讀取該屬性的值，所以我可以將它粘貼到標註放在那裏的字符串。必須有一種方法來做到這一點，對吧？但是如何？如何將附加到CRM標註中的表單上的字段？

編輯：代碼片段：


public override PreCalloutReturnValue PreCreate(CalloutUserContext userContext, CalloutEntityContext entityContext, ref string entityXml, ref string errorMessage) 
    { 
    // Variables 
    string prefix = "no_init"; 

    XmlDocument entityDoc = new XmlDocument(); 
    entityDoc.LoadXml(entityXml); 

    XmlNodeList propertyList = entityDoc.GetElementsByTagName("Property"); 
    XmlElement competitorNumberValue = null; 
    XmlElement properties = (XmlElement) entityDoc.GetElementsByTagName("Properties")[0]; 
    XmlElement competitorNumberElement = entityDoc.CreateElement("Property"); 

    // Find prefix -- this is the part I don't know how to do 
    prefix = Convert.ToString(?????); 

      /* 
       Other stuff gets calculated here, which works fine. New value gets written to the attribute here as well. 
      */ 

    return PreCalloutReturnValue.Continue; 
    }

另一個編輯：我只是想這樣的想法，這是我在網上找到了和這實際上造成了一個CRM服務器錯誤保存：



      string nameSpaceValue = entityDoc.ChildNodes[0].Attributes["xmlns"].Value; 
      XmlNamespaceManager xsn = new XmlNamespaceManager(entityDoc.NameTable); 
      xsn.AddNamespace("z", nameSpaceValue); 
      string entityXpath = "//z:new_name"; 
      XmlNode new_nameNode = entityDoc.SelectSingleNode(entityXpath, xsn); 

      // Find prefix 
      prefix = ((XmlElement)new_nameNode).GetAttribute("new_name").ToString();

你能發佈您的代碼？這是完全可能的，但很難看出你可能做錯了沒有一個例子。 – Matt 2010-07-16 19:08:38

嗯，我不知道自己做錯了什麼，不知道如何做到這一點，但我會在一秒內用適當的代碼片段更新我的問題。 – extarbags 2010-07-16 19:10:23

我認爲，你應該把它包含在一個Dynamic實體中，以便你可以直接訪問每個屬性。
