Question

I don’t understand why this doesn’t work.

I am using a file to set bunch of in my program. I am reading the content of a file by using separators. My text file looks like this: The Message$1$5001&5002&5003

When I am trying to read a value of a numeric values in my file I am getting error: Input string was not in a correct format. on line: nudInterval.Value = decimal.Parse(setting);

This is how I do it:

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);
        }
    }
}

This is because half of your separators are &, not $.

This means you are trying to execute

nudInterval.Value = decimal.Parse("5001&5002&5003");

which will fail.

If those are valid values, you could change your split statement:

string[] allSettings = lastUsed.Text.Split(new char[] {'$', '&'});

or replace & with $ before splitting:

string[] allSettings = lastUsed.Text.Replace('&', '$').Split('$');
