Add extra ,00 by number if nothing is left "," or "."

Question

Where my problem lies is if a user writes 200 then it makes a mistake.

But that error only because I have for example written 200.

I have tried different things that have led to it approving only the number 200 if it is.

My Models:

[Required(ErrorMessage = "Money")]
[RegularExpression(@"\d+(\.\d{1,2})?", ErrorMessage = "Error")]
[Range(0, 99999.99, ErrorMessage ="Error")]
[DataType(DataType.Text)]
[Display(Name = "Money")]
public string Pay { get; set; }

in my CompaniesController i get the value from "Pay"

decimal PayValue = model.Pay.ToString().PayValue();

And thus, in PayValue, I have done so that it divides the price in proportion to having to throw "," in between two numbers.

public static decimal PayValue(this string str)
    {
        string[] pay;
        pay = str.ToString().Split('.');
        return Convert.ToDecimal(pay[0] + "," + pay[1]);
    }

Here I would like it to run through and be successful.

Error here: 200
Error here: 20000

Thus, I would like if a customer writes the two numbers oven over then it must itself add ,00 only if nothing ,00 is add after the whole number.

Code fails if I only write 200, What I want it to be is that it must go through and even add ,00 after the number.

If I'm understanding correctly you are just wanting to show the amount formatted as currency? If so check this out https://stackoverflow.com/questions/4842332/currency-format-for-display — akaBase, Jul 05 '19 at 19:12
This is a case where I would recommend a unit test as the universal language. It's very, very hard to understand the problem you're trying to solve. But if you expressed it as a failing unit test (maybe a parameterized test) then there would be no barriers. — Scott Hannen, Jul 05 '19 at 19:28
