Question

I have a C# function that look like this:

bool func(string name, bool retry)
{
    string res= SomeOp(name);
    if(res=="whatever")
    {
        return true;
    }
    else
    {
        if(retry)
            return func(res, false)
    }
    return false;
}

I want the retry flag to be hidden from the user calling the function.

I need the function to be executed only twice.

I don’t want to make the function static, and I don’t want to declare an outside variable for this simple need., and a default value is not enough.
Is there is any other elegant solution?

You can do something like this

public bool func(string name)
{
    var retryCount = 1;

    string result = string.Empty;
    while (retryCount <=2)
    {
        result = DoSomething(name);

        if(result =="Whatever")
            return true;

        retryCount ++;
    }

    return false;


}
