Question

In my program there are multiple players who’s stats can all be increased at the same time.

Player 1 is represented by staminaTextBox[0] skillTextBox[0] LuckTexBox[0]

Player 2 is represented by staminaTextBox[1] skillTextBox[1] LuckTexBox[1]

etc.

I need my IncreaseStat method to deal with 3 different type of Textbox Overload e.g. Stamina, Skill, Luck

private void StaminaIncBtn_Click(object sender, EventArgs e)
{
    IncreaseStat(staminaText[0]);
}

private void LuckIncBtn_Click(object sender, EventArgs e)
{
    IncreaseStat(luckText[0]);
}

private void IncreaseStat(TextBox statText)
{
    for (int i = 0; i < 5 ; i++)
    {
        statText[i].Text = "Altered";
    }
}

This method is used to increase all 5 players stats at the same time.

It works fine if they are not control arrays, however I need them to be. I get the error
"Cannot apply indexing with [] to an expression of type 'System.Windows.Forms.TextBox". It applies to that fact that inside the method I am saying statText[i].

I do not understand how to get around this problem. Any suggestions would be more than welcome.

Thank you for your time.

Would this be sufficient (with possible changes by yourself for your need)?

private void IncreaseStat() {
    foreach (TextBox textBox in this.Controls.OfType<TextBox>().Where(x => x.Name.Contains("stamina") || 
            x.Name.Contains("skill") || 
            x.Name.Contains("Luck"))) {
        textBox.Text = "Altered";
    }
}
