我想拥有以下测试步骤类结构:

[Binding]
public class BaseStep
{
    [Given(@"there is a customer")]
    public void GivenThereIsACustomer(Table table)
    {
        HandleCustomer(table);
    }

    protected virtual void HandleCustomer(Table table)
    {
    }
}

[Binding]
public class FeatureOneStep : BaseStep
{
    protected override void HandleCustomer(Table table)
    {
         // feature one action
    }

    [Given(@"feature one specific step")]
    public void GivenFeatureOneSpecificAction(Table table)
    {
        // do something
    }

}

[Binding]
public class FeatureTwoStep : BaseStep
{
    protected override void HandleCustomer(Table table)
    {
         // feature two action
    }

    [Given(@"feature two specific step")]
    public …

我有以下ServiceContract和DataContract类:

[ServiceContract] 
public interface IWcfService 
{ 
    [OperationContract] 
    Response GetData(); 
} 

[DataContract]
public class Response 
{ 
    [DataMember] 
    public Dictionary<string, object> Data { get; set; } 
} 

当Response.Data字典的值为int,string,double或任何其他"简单"基元类型时,WCF可以成功序列化该对象.但是当Response.Data字典的值为List <string>类型时,客户端在接收到数据并尝试反序列化时抛出以下异常:

Message=The formatter threw an exception while trying to deserialize the message:

The InnerException message was 'Error in line 1 position 990.
