How to put a non static Method into a String- .Split()

Question

I try to make a little console application in C#, where I have a given text, which cuts the part, you gave in the input (Console.ReadLine()), out. If you wonder: I am going to make a switch statement, in case the user input, cannot be found in the given text. Heres my Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ForTests
{
class Program
{
class SplitText
{
public static string text = "You can cut here any word you want in this text. ANY. So do it. Now."; // The uncut text in string

private string input; // The methods which are carring the .ReadLine input
public string Input
{
get { return input; }
set { input = value; }
}

string[] words = text.Split(Input); // Here is the text.Split, where the Input method does not work

public void Write() // Here is the method to assemble the text back together
{
for (int i = 0; i < words.Length; i++)
{
Console.Write(words[i]);
}
}

public void t() //This Method shows the given text in the console
{
Console.WriteLine(text);
}

}
static void Main(string[] args)
{

SplitText s = new SplitText();
s.Input = Console.ReadLine();
// Here I defined Input as Console.ReadLine()

Console.WriteLine(": ");
s.t();
// This shows the uncut text

Console.WriteLine("Cutted text: ");
s.Write();
// Here you get the cutted text

Console.ReadKey();
}
}
}

Answer 1

string[] words = text.Split(Input);

This line is ran when the SplitText object is created (SplitText s = new SplitText();) in Main, not when the input string value is set. So when it is ran input has no value. Also the Split method takes a char[], or string[] as a parameter, not a String.

So you may need to re-think your approach.
I.E. get rid of the input property, or change its type to a string[] and add to it from the object. Wrap the error line in a method of its own, which means you'd need to also extract the words variable out of the method and make it a property as well so that the Write method has access to it, or move the line into the Write method. and so on.....

Answer 2

Thanks for your Answer! I have now reworked my Code a little on this base:

class Program {
static void Main() {
string value = "cat\r\ndog\r\nanimal\r\nperson";
// Split the string on line breaks.
// ... The return value from Split is a string[] array.
string[] lines = Regex.Split(value, "\r\n");

foreach (string line in lines) {
Console.WriteLine(line);
}
}
}

And came with this Solution and now it works! My Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Text.RegularExpressions;

namespace ForTests
{
class Program
{
class SplitText
{

public static string text = "You can cut here any word you want in this text. ANY. So do it. Now.";

public string input; // stores user input

public void Input() // method to take a user input
{
input = Console.ReadLine();
}

public void Write() // takes input as a reference, what it should split and reassembles it then
{
string[] words = Regex.Split(text, input);
for (int i = 0; i < words.Length; i++)
{
Console.Write(words[i]);
}
}

public void t() //This Method shows the given text in the console
{
Console.WriteLine(text);
}

}
static void Main(string[] args)
{

SplitText s = new SplitText();

Console.WriteLine("Uncutted text: ");
s.t();
// This shows the uncut text

s.Input(); // takes the user input

Console.WriteLine("Cutted text: ");
s.Write();
// Here you get the cutted text

Console.ReadKey();
}
}
}
