WCF查詢對象

我還是一個WCF的解決方案，應該能夠查詢程序的後臺並返回結果工作的數組。WCF查詢對象

後端存儲對象的字典叫Groups，他們可以用功能進行查詢，如：

GetGroup通過ID
GetGroups獲得單組獲得通過標籤組的列表。

GetGroup可以正常使用WCF測試客戶端和我構建的應用程序。並將它與下面的代碼表的工作方式應用：完美

 List<string> values = new List<string>(); 
     GroupServiceClient client = new GroupServiceClient("WSHttpBinding_IGroupService"); 
     www.test.co.uk.programme.programme Group = new www.test.co.uk.programme.programme(); 
     DateTime time = DateTime.Now; 
     values.Clear(); 
     client.Open(); 

     Group.number = textBox1.Text; 
     client.GetGroup(ref time, ref Group); 

     GroupStorageMessage toReturn = new GroupStorageMessage(); 
     toReturn.group = Group; 

     selectedGroupId = Convert.ToString(toReturn.group.number); 

     values.Add(Convert.ToString(toReturn.group.number)); 
     values.Add(Convert.ToString(toReturn.group.name)); 

     listBox1.ItemsSource=values; 

     client.Close();

的GetGroups作品與WCF測試客戶端，但不是我的申請。

它發送查詢，因爲它應該，但它確實返回Null（請注意，此代碼是形成另一種應用程序，我使用的是基準而不是代理文件）

 ServiceReference1.programme Group = new ServiceReference1.programme(); 
     ServiceReference1.GroupServiceClient Client = new ServiceReference1.GroupServiceClient(); 
     DateTime Time = DateTime.Now; 

     Client.Open(); 

     string[] aa = new string[1]; 

     aa[0] = textBox1.Text; 
     Group.tags = aa; 
     Client.GetGroups(ref Time, Group); 

     ServiceReference1.GroupArrayMessage toReturn = new ServiceReference1.GroupArrayMessage(); 

     ServiceReference1.programme[] Groups = new ServiceReference1.programme[1]; 

     toReturn.groups = Groups; = returns null

在新ServiceReference1。方案[1];我其實猜測要放在那裏。

接口：

[ServiceContract(Namespace = "http://www.Test.co.uk/groupstorage")] 
public interface IGroupStorageService 
{ 
    /** 
    * Get a group from the collection of groups 
    */ 
    [OperationContract] 
    GroupStorageMessage GetGroup(GroupStorageMessage message); 
    /** 
    * Add a group to the collection of groups 
    */ 
    [OperationContract] 
    void AddGroup(GroupStorageMessage message); 
    /** 
    * Remove a group from the collection of groups 
    */ 
    [OperationContract] 
    void RemoveGroup(GroupStorageMessage message); 
    /** 
    * Update a group in the collection of groups 
    */ 
    [OperationContract] 
    void UpdateGroup(GroupStorageMessage message); 

    [OperationContract] 
    GroupArrayMessage GetGroups(GroupStorageMessage message); 
}

消息合同：

[MessageContract] 
public class GroupArrayMessage 
{ 
    /** 
    * Message header is the timestamp when the message was created 
    */ 
    [MessageHeader(Name = "time")] 
    public DateTime Time; 
    /** 
    * Message body is a collection of Users 
    */ 
    [MessageBodyMember(Name = "groups")] 
    public Group[] Groups; 
}

組觸點（有時被稱爲程序）

[DataContract(Namespace = "http://www.test.co.uk/programme", Name = "programme")] 
public class Group 
{ 
    /** 
    * The number representing the Programme (Programme ID) 
    */ 
    [DataMember(Name = "number")] 
    public string Number; 
    /** 
    * The name of the Programme 
    */ 
    [DataMember(Name = "name")] 
    public string Name; 
    /// <summary> 
    /// Add Tags 
    /// </summary> 
    [DataMember(Name = "tags")] 
    public string[] Tags;

，請複製粘貼服務接口的代碼和服務實現類。也請粘貼Group類的代碼。這將是比較容易回答的時候代碼將可 – 2012-04-10 16:17:06

PS我知道查詢發送形式的應用是好的，作爲後臺日誌系統將其標記爲一個成功的查詢，並在日誌文件中 – user1211929 2012-04-10 16:17:26

酷派問題返回結果。怎麼樣app.config文件。它們在你的兩個應用程序中是否相同？ – 2012-04-10 17:38:34

我終於找到了解決方案：

 GroupService.GroupArrayMessage toReturn = new GroupService.GroupArrayMessage(); 


     GroupService.programme[] Groups = Client.GetGroups(ref Time, Group); 

     toReturn.groups = Groups; 

     listBox1.ItemsSource = toReturn.groups;
