无法从IEnumerable <T>转换为IEnumerable <T>

我最近进入了一个前端编程世界，但是正在回到C＃中从事我正在从事的项目。我正在定义一些模型和通用功能，并遇到以下错误：

错误3参数2：无法从'System.Collections.Generic.IEnumerable<T>[c：\ Program文件（x86）\参考程序集\ Microsoft \ Framework.NETFramework \ v4.5 \ mscorlib.dll]转换为'System.Collections.Generic.IEnumerable<T>[c：\ Program Files（x86）\参考程序集\ Microsoft \ Framework.NETFramework \ v4.5 \ mscorlib.dll]”

错误来自以下函数中的return语句：

public static PagedResult<T> Create<T, TEntity>(IOrderedQueryable<TEntity> query, PagedRequest pagedRequest, Func<TEntity, T> converter)
        where T : class
    {
        var count = query.Count();

        if (pagedRequest.SortInfo.Fields.Any())
        {
            var firstPass = true;
            foreach (var sortOrder in pagedRequest.SortInfo.Fields)
            {
                if (firstPass)
                {
                    firstPass = false;
                    query = sortOrder.Direction == SortDirection.Ascending
                                ? query.OrderBy(sortOrder.Field) :
                                  query.OrderByDescending(sortOrder.Field);
                }
                else
                {
                    query = sortOrder.Direction == SortDirection.Ascending
                                ? query.ThenBy(sortOrder.Field) :
                                  query.ThenByDescending(sortOrder.Field);
                }
            }
        }

        query = (IOrderedQueryable<TEntity>) query.Skip((pagedRequest.Page - 1) * pagedRequest.PageSize).Take(pagedRequest.PageSize);

        var list = new List<T>();
        foreach (var entity in query)
        {
            list.Add(converter(entity));
        }

        return Create(pagedRequest, list.AsEnumerable(), count);
    }

和创建功能：

static public PagedResult<T> Create(PagedRequest request, IEnumerable<T> data, long totalCount)
    {
        var result = new PagedResult<T> {Status = ResultStatus.Successful, Data = data.ToArray()};

        result.Count = result.Data.Count();
        result.TotalCount = totalCount;

        result.Page.Index = request.Page;
        result.Page.Size = request.PageSize;
        if (result.Page.Size > 0)
        { result.Page.Count = (long)Math.Ceiling((double)totalCount / result.Page.Size); }

        return result;
    }

似乎无法获得编译时错误。有人对如何解决此问题有任何想法吗？
