Question

I am trying to convert decimal value to string.

My coding is this:

public ActionResult Search(string searchString)
    {
    product = product.Where(a => a.model.ToUpper().Contains(searchString.ToUpper())
                               || a.Category.name.ToUpper().Contains(searchString.ToUpper()) 
                               || SqlFunctions.StringConvert((decimal)a.displaySize).Contains(searchString));
    return View(product.ToList());
    }

When searchString value is ‘5’ instead of decimal value, it will be shown product list. However, if searchString value is ‘5.5’, it won’t display the product list.

I don’t know why really..

Could you help me?

Many thanks.

It would probably be easier to convert searchString to a decimal, try this:

public ActionResult Search(string searchString)
{
    var searchVal = decimal.Parse(searchString);

    product = product.Where(a => a.model.ToUpper().Contains(searchString.ToUpper())
                           || a.Category.name.ToUpper().Contains(searchString.ToUpper()) 
                           || a.displaySize == searchVal);
    return View(product.ToList());
}

You may want to use TryParse instead to ensure typesafety, depending on where searchString is coming from
