How to Add Spaces before Capital letter in a string using C#?


In my MVC project, I am getting dropdown text data as "NoEffect", "FadeOut" etc, now I would like to show user as "No Effect", "Fade out" etc, show how can I achieve it using C#?

Any method would work, using regex or without using regex.

Try using this below Linq code(without using regex) to add space before capital letters

var YourString= "NoEffect";

//get output as "No Effect"
@string.Concat(YourString.Select(x => Char.IsUpper(x) ? " " + x : x.ToString())).TrimStart(' ');

This should work.

This looks easier than using regex, not sure about performance though 0

Here is the simple program to add space before capital letters using regex in C#

using System;
using System.Text.RegularExpressions;
					
public class Program
{
	public static void Main()
	{
		var oldvalue= "ThisIsTest";
		var newValue = Regex.Replace(oldvalue, "([a-z])([A-Z])", "$1 $2");
		Console.WriteLine(newValue);
	}
}

Output:

This Is Test

You can check the fiddle here https://dotnetfiddle.net/4V0v70 but above Linq Solutions looks easy and simple to me.
