c# - Please explain System.Linq.Enumerable.Where(Func<T, int, bool> predicate) -

May 15, 2011

I can not understand the meaning of the MSDN document for this surcharge, in which case there are two arguments Estimated, represents the indicator of the source element, whatever it means (I thought that a calculation was a sequence and you are not able to see more than the next item, very few are not indexing it).

Can someone please explain the use of this surcharge, and in particular the fun that is for int and how is it used?

int parameter current running current within Indicates the item's indicator whenever you call one of the LINQ expansion methods, you do not guarantee in principle to achieve returning objects in the same sequence, but you know that they are all one Times are returned and indexes can be appointed

Example:

 If you know If the query object is a  list  , then you are guaranteed.    var results 1 = myEnumerable.Where ((item, index) => index & lt; 4); Var result 2 = myEnumerable.Take (4); // Results 1 and Results are equivalent 2.

I'm assuming you followed the PHP version of your tutorial. If so, look at listing for service.php under "service of small URL". In section round line 11 where it determines the position of 301, you can redirect with the database update. Something like    $ query = mysql_query ("update`" $ database. "` .```_AL_DIRED`Set count = count + 1 where` small '=' ".mysql_escape_string ($ short) , $ Db); $ Line = ...

However, what I need to do is here something like gallery here Only completes without javascript and ajax:     I want a selection number to show below the main image as soon as the user clicks the thumbnail, the page Selected new Highlight the image and the series of thumbnails on boto goes forward one by one if its not the last image.   How do I do this? Do I need a quick and dirty way to do this? I am using php and mysql for the database here - just need code to show 'paged' images below the main image. I know how to install everything i.e. Thumbnail size etc ...      I do not know the number of your rows in MySQL for T-SQL As there is a ROWNUMBER () function, but to do this, it is a smart way to sequential numbering of your images in the database. From there, you ask something ...
