Method chaining in functional programming relies on extension methods. As we have already discussed in Chapter 1, Tasting Functional Style in C#, method chaining will make our code easier to read since it can decrease the lines of code. For the sake of code readability in the extension method, let's take a look at the following code, which we can find in the CodeReadability.csproj project:
using System.Linq;
namespace CodeReadability
{
public static class HelperMethods
{
public static string TrimAllSpace(string str)
{
string retValue = "";
foreach (char c in str)
{
retValue +=!char.IsWhiteSpace(c) ?c.ToString() :"";
}
return retValue;
}
public static string Capitalize(string str)
{
string retValue = "";
string[] allWords = str.Split(' ');
foreach...
