c# - 委托(delegate)似乎没有注册 'params'

Question

params C# 的关键字允许 Array 和 parameter-list 之间等价，不是吗？

遗憾的是，在我的实现中，情况并非如此。

private Entities queryType(String entitiesType, params KeyValuePair<String, object>[] values)
{
    addStandardHeaders();
    String query = parsePredicate(values);
    Task<HttpResponseMessage> filterTask = client.GetAsync(client.BaseAddress + RESTapi.ALMentitiesQuery(domain, project, entitiesType, query));
    Task.WaitAny(filterTask);
    //Callback:
    HttpResponseMessage result = filterTask.Result;
    if (result.IsSuccessStatusCode)
    {
        updateCookies(client.BaseAddress+RESTapi.ALMentitiesQuery(domain, project, entitiesType, query));
        mainHeaders.Clear();
        Task<Stream> output = result.Content.ReadAsStreamAsync();
        Task.WaitAny(output);
        //Callback:
        return (Entities)fromJSON(output.Result, typeof(Entities)); 
    }
    else
    {
        util.Exception exception = getException(result);
        throw new HttpException(exception.Title);
    }
}

委托(delegate):

public delegate Entities SubTypeQuery(String subType, params KeyValuePair<String, object>[] values);

应用中:

public List<Run> getRuns()
{
    List<Entity> selection = ((Entities)subTypeSelector.DynamicInvoke(
        ALMObject.Run.entitiesName(),
        (new KeyValuePair<String, object>("testcycle-id", id))
    )).entities.ToList<Entity>();

    List<Run> runSet = new List<Run>();
    foreach (Entity element in selection)
        runSet.Add(new Run(element, subTypeSelector));
    return runSet;
}

在运行时，我得到一个类型异常:“无法将 KeyValuePair<String, object> 转换为 KeyValuePair<String, object>[]”。这呈现 params完全没用。 有什么建议吗？

为什么要动态调用？您似乎知道所有参数的类型。

简单地调用委托(delegate)有什么问题？

List<Entity> selection = ((Entities)subTypeSelector(
    ALMObject.Run.entitiesName(),
    (new KeyValuePair<String, object>("testcycle-id", id))
)).entities.ToList<Entity>();
