Question

See more:

in txt file i have a sentence: Please write any Sentence.
i must create function which has 2 parameter` first file address,the second is any word.
This function must return how many times did encounter the word in the sentence.
For example if i will call it in main like this`

Console.WriteLine(Counter(hasce,"any"));

it will print 1, because there is 1 word name of "any" in sentence.

What I have tried:

I've tried like this`

static public int Counter(string address,string word)
        {
            int myword= 0;
            string text = File.ReadAllText(address);
            if (word == text)
            {
                myword++;
            }
            
            return myword;
        }

static void Main(string[] args)
        {
           Console.WriteLine(Counter(address,"any"));
        }

It depends on what you mean "word"...
An address may have numbers and other signs: "post 444, SampleCity, Huge Street 45"
How many words is in that string?

4 words here is "Please write any sentence",this is a just text in txt file,i created txt file and wrote this small text in file, now i need write any word for example "any" and it will return 1, but with this function it printed 0. why?

PLease, read my comment to the question.

You have to Split[^] string on spaces, for example:

C#

string address = "Please write any Sentence";
string filter = "any";

int counter = address.Split(new string[]{" "}, StringSplitOptions.RemoveEmptyEntries).Count(x=>x==filter);
Console.WriteLine("{0}", counter);

[EDIT]
I forgot to mention about upper/lower letters! Note that comparison: ("any"=="Any") returns false.
I'd strongly recommend to read this:
How to: Compare strings (C# Programming Guide) | Microsoft Docs[^]
String.Compare Method (String, String, Boolean) (System)[^]

Good luck!

[EDIT #2]
Due to OP's comments, here is a complete example:

C#

void Main()
{
	
	string path = @"D:\data.txt";
	string find = "any";
	string[] lines =  File.ReadAllLines(path);
	int cTotal = 0;
	
	foreach(string line in lines)
	{
		cTotal += Counter(line, find);
	}
	
	Console.WriteLine("A '{0}' has been found {1} time", find, cTotal);
	
}

// Define other methods and classes here
public static int Counter(string line, string findword)
{
	int c= 0;
	
	string[] words = line.Split(new string[]{" "}, StringSplitOptions.RemoveEmptyEntries);
	foreach(string word in words)
	{
		if (string.Compare(word, findword, System.Globalization.CultureInfo.InvariantCulture, System.Globalization.CompareOptions.IgnoreCase)==0)
		{
			c++;
		}
	}
	return c
}
