How to specify list parameters in WCF Test Client (WcfTestClient.exe)?
wcf
Solution
Type `length=1` in the box. A `+` sign will appear next to the request parameter name. Click on it, then on the `[0]` node which indicates the first element in the array and set its values as usual.
Problem
I am using WCF Test Client (WcfTestClient.exe) for testing one of my wcf services. I have a message contract which has a list of DataContracts as : My message contract is as follows : ``` [MessageContract] public class UpdateInvoiceStatusesRequest { private List<InvoiceStatusHistory> _invoiceStatusHistory; [MessageBodyMember(Order = 0)] public List<InvoiceStatusHistory> InvoiceStatusHistory { get { return _invoiceStatusHistory; } set { _invoiceStatusHistory = value; } } } ``` and my data contract is : ``` [DataContract] public class InvoiceStatusHistory { private int _invoiceId; private int _status; private string _comment; private string _timeStamp; [DataMember] public int InvoiceId { get { return _invoiceId; } set { _invoiceId = value; } } [DataMember] public string Comment { get { return _comment; } set { _comment= value; } } [DataMember] public int Status { get { return _status; } set { _status = value; } } [DataMember] public string TimeStamp { get { return _timeStamp; } set { _timeStamp = value; } } } ``` when i am using WcfTestClient.exe to test the service with `UpdateInvoiceStatusesRequest` message contract it shows the value of `InvoiceStatusHistory` as length = 0, now i don't know how can i add the objects of `InvoiceStatusHistory` in `List<InvoiceStatusHistory>` ? Does anyone has any idea about it, please help me?
