求助错误处理:在以下方法或属性之间的调用不明确:“System.Math.Ceiling(decimal)”和“System.Math.Ceiling(double)”

问题代码:
private void Page_Load(object sender, System.EventArgs e)
{
// Save the search string parameters to String variables
string searchString = Request.QueryString["Search"];
string allWords = Request.QueryString["AllWords"];
string pageNumber = Request.QueryString["PageNumber"];
string productsOnPage = Request.QueryString["ProductsOnPage"];

// Perform the search and get back the number of results
// The search results will be read from ProductsList.ascx
int howManyResults;
howManyResults = Catalog.SearchCatalog(searchString, pageNumber, productsOnPage, allWords);

// Do you have any results?
if (howManyResults == 0)
{
titleLable.Text = "Your search for <font color=red>" + searchString + "</font> generated no results.";
previousLink.Visible = false;
nextLink.Visible = false;
pageNumberLable.Visible = false;
}
else
{
titleLable.Text = "Your search for <font color=red>" + searchString + "</font> generated " + howManyResults.ToString() + " results:";

// Calculate how many pages of results
int howManyPages = (int)Math.Ceiling(howManyResults / (Convert.ToInt32(productsOnPage)));

// Show "Page x of y" text
pageNumberLable.Text = "Page " + pageNumber + " of " + howManyPages.ToString();

// Initialize the "Previous" link
if (pageNumber == "1")
{
previousLink.Enabled = false;
}
else
{
previousLink.NavigateUrl = Request.Url.AbsolutePath + "?Search=" + searchString + "&AllWords=" + allWords + "&PageNumber=" + (Convert.ToInt32(pageNumber) - 1).ToString() + "&ProductsOnPage=" + productsOnPage;
}

// Initialize the "Next" link
if (pageNumber == howManyPages.ToString())
{
nextLink.Enabled = false;
}
else
{
nextLink.NavigateUrl = Request.Url.AbsolutePath + "?Search=" + searchString + "&AllWords=" + allWords + "&PageNumber=" + (Convert.ToInt32(pageNumber) + 1).ToString() + "&ProductsOnPage=" + productsOnPage;
}
}
}

使用(decimal)或(double)强制转换一下Ceiling方法里的参数。
