Question

I am trying to make error free user input. When there is a one split symbol user might type it and create an error which I must fix before executing creating more lines of code. Is there a way of splitting a string using for example $%$ instead of just $ character?

This is how I do splitting using one character:

if (!lastUsed.EmptyFile())
{
    string[] allSettings = lastUsed.Text.Split('$');
    int settingCount = 0;

    foreach (string setting in allSettings)
    {
        settingCount++;

        if (settingCount == 1)
        {
            txtText.Text = setting;
        }
        else if (settingCount == 2)
        {
            if (setting == "0") tbType.SelectedTab = tbInterval;
            else tbType.SelectedTab = tbRange;
        }
        else if (settingCount == 3)
        {
            nudInterval.Value = decimal.Parse(setting);
        }
        else if (settingCount == 4)
        {
            nudMin.Value = decimal.Parse(setting);
        }
        else if (settingCount == 5)
        {
            nudMax.Value = decimal.Parse(setting);
        }
    }
}

You can use a string as the delimiter.

string[] delim = new string[] {"$%$"};

string[] allSettings = lastUsed.Text.Split(delim, StringSplitOptions.None);
