提供分页的Request和Reponse基类

[witskeeper]

考虑是否在Primitives包中提供？

大概的伪代码如下
···
public class PageRequest
{
public int PageIndex { get; set; }
public int PageSize { get; set; }
}

public class PageResponse
{
public int PageIndex { get; set; }
public int PageSize { get; set; }
public int TotalCount { get; set; }
public IEnumerable Items { get; set; }
}
