起訂量不及格的所有對象的方法

Question

我上面有一個方法的接口是這樣定義的：

IEnumerable<dynamic> ExecuteDynamic(string query, object param = null) 

我想測試的代碼調用像這樣的接口：

var result = _repository.ExecuteDynamic("cart_getNewXsession", new 
{ 
    HTTP_USER_AGENT = _context.Request.UserAgent, 
    RHID = _context.Request.UserHostAddress, 
    scid = GetSourceCode(), 
    wsid = _systemSettings.GetWSID(), 
    HTTP_REFERER = _context.Request.UrlReferrer == null ? "" : _context.Request.UrlReferrer.ToString(), 
    QUERY_STRING = _context.Request.Url.Query 
}); 

我試圖調用模擬出這種方法是這樣的：

var repository = new Mock<>(); 
var sprocReturnValue = (new[] { (dynamic)new { guid = "123456" } }).AsEnumerable(); 
repository.Setup(x => x.ExecuteDynamic("cart_getNewXsession", It.IsAny<object>())) 
         .Returns<IEnumerable<dynamic>>(x => sprocReturnValue); 

然而，當我在測試中運行這個了，我得到的錯誤：

System.Reflection.TargetParameterCountException : Parameter count mismatch. 

    at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks)

    Services\Session\BuildXS.cs(78,0): at Core.Tests.Services.Session.BuildXS.When_XS_In_Cookie_Use_XS_From_Cookie() 

在這種情況下，我應該如何設置我的模擬對象？

問題是Returns方法。

下面的工作（在LINQPad爲例）：

void Main() 
{ 
    var repository = new Mock<IRepository>(); 
    var sprocReturnValue = (new[] { (dynamic)new { guid = "123456" } }).AsEnumerable(); 
    repository.Setup(x => x.ExecuteDynamic("cart_getNewXsession", It.IsAny<object>())) 
       .Returns(sprocReturnValue); 

    var _repository = repository.Object; 
    var result = _repository.ExecuteDynamic("cart_getNewXsession", new { Whatever = 0 }); 

    Console.WriteLine(result.First().guid); // 123456 
} 

public interface IRepository 
{ 
    IEnumerable<dynamic> ExecuteDynamic(string query, object param = null); 
}
