Populate DataTable in a WCF Service

Question

Hello i'm trying to populate a Datatable in a C# WCF Service.

In the Iservice part i have a class :

[DataContract]  
public class Batiments  
{  
	[DataMember]  
	public DataTable DtNavires { get; set; }  
}  

And the method :

[OperationContract]  
	Batiments GetNavires();  

In the Service Part :

public Batiments GetNavires()  
    {  
        XDocument doc = XDocument.Load(FilePath);  
        Batiments b = new Batiments();  
        DataTable dt = new DataTable("Navires");  
  
        dt.Columns.Add("Type");  
        dt.Columns.Add("Nom");  
        string[] arr = new string[2];  
  
        var dr = from n in doc.Descendants("Nom")  
                 select new string[]{  
                         arr[0] = n.Attribute("Type").Value,  
                         arr[1] = n.Attribute("Nom").Value  
                     };  
  
        foreach (var item in dr)  
        {  
            dt.Rows.Add(item[0], item[1]);  
        }  
        b.DtNavires = dt;  
        return b;  
    }  

When i start the service in Debug mode (F5) i can see that this method is not available since it's using the Batiments type.

What is wrong in this service ???

Hi @jean-francois collombet ,

First you can open your config file to see if the client configuration has been added. Then make sure the client and server bindings are the same. Please share your configuration file if you can. Thanks.
