Coding like writing a book

If you write better code then it's just easier to read it.
Just have a look at below examples and you will know what I am talking about.

Code Sentence that appears in my mind


public int GetTotalCost(DataTable products)
{
int totalCost = 0;
foreach (DataRow product in products.Rows)
{
totalCost += (int)product["Price"];
}
return totalCost;
}




For each product that is in products
get its price and add it to the total cost.


public int GetTC(DataTable dt)
{
int tc = 0;
for (int i = 0; i < dt.Rows.Count; i++)
{
tc += (int)dt.Rows[i]["Price"];
}
return tc;
}




For each i in range from 0 to dt.Rows.Count – 1 get ith
element of dt.Rows and get its price. Then add the price to tc.

Using OR mapping tools we can even replace DataTable with ProductCollection and DataRow with Product.
