How I could loop over an array of objects and add a property from each object to a variable using Linq?












1















I have an array that contains the several instances of the following struct



public struct IMAGE_BASE_RELOCATION

{

    public uint VirtualAddress;

    public uint SizeOfBlock;

}


I want to add the value of SizeOfBlock to a variable for every struct in the array



Currently, I am doing this like this



var count = 0;



foreach(var structure in theArray)

{

    count += (int) structure.SizeOfBlock;

}


I was wondering how I could use linq to do this






c# linq

          you can do it by this way.



          var count = theArray.Sum(x=>x.SizeOfBlock);
