C# LINQ - Partitioning the List Collection Into Chunks

















Partitioning is the key part while working with the large collections in programming. LINQ helps in dividing the huge collection into chunks. 

Below code snippet takes the list and the chunk size and yields the chunks from the collection.

public static IEnumerable<List<T>> Partition<T>(List<T> source, Int32 size)
{
    for (int i = 0; i < Math.Ceiling(source.Count / (Double)size); i++)
        yield return new List<T>(source.Skip(size * i).Take(size));
}

Test Results:





JavaScript - window.location.origin is not working in Internet Explorer


window.location.origin does not work on Internet Explorer. 

Follow the below code which will set the window.location.origin value by concatenating the portions of the URL. 

 if (!window.location.origin)
    window.location.origin = window.location.protocol + '//' + window.location.hostname + (window.location.port ? (':' + window.location.port) : ''); 
}

window.location properties

window.location.protocol         - Return the protocol of the current URL
window.location.hostname      - Returns the domain name of the web host
window.location.port                  - Number of the internet host port (of the current page)
