Error CS1503 Argument 1: cannot convert from 'System.Windows.Forms.TextBox' to 'string'

What I have tried:

private void fullTotalButton_Click(object sender, EventArgs e)
{
const decimal TAXRATE = 0.12m;
decimal val1 = decimal.Parse(MealCost.Text);
decimal result = val1 * TAXRATE;
taxAmount.Text = result.ToString("C");
decimal outcome = val1 + result;
fullTaxLabel.Text = outcome.ToString("C");
decimal val7 = decimal.Parse(tipCalculate);
decimal ending = val7 + outcome;
tipamountBox.Text = ending.ToString("C");

Gotta get that homework done before the teacher finds out. I can't really tell from your code but somewhere you are referencing a textbox without using the .Text property to either set the value of it, or get the value from it.

One of the objects in this code is of type TextBox and you are trying to use it somewhere, string type is expected.

Since you haven't shared anything other than this code, we are not able to help you with this as we don't know anything at all; what your typing for objects is, what comes from where.

The error message is plain. And where the error is, is pretty clear too. But that is all I care to do for such a rude posting.

Hints:
1. On which line was this exception reported?
2. Post ALL the relevant code ... for example what is fullTaxLabel? Do I trust your naming conventions? No.
3. To get a timely response to your problems
a) Avoid anything that suggests this may be "urgent" to you (it is not)
b) respond immediately to questions in comments (you haven't)
c) Include all the relevant information

Solution 1

Look at this line:

decimal val7 = decimal.Parse(tipCalculate);

That needs to be a string parameter - so reference the Text property:

decimal val7 = decimal.Parse(tipCalculate.Text);

In future, if you look at the error message in Visual Studio, you can double click it, and you will be taken to the line with the error directly.

Not to mention the jump from val1 to val7. Whatever happened to descriptive variables? Well done though, this seems plausible as the issue despite the lack of any description of the types involved.

What gets me is that it would have been just as easy to type "cost" instead of "val1", "tip" instead of "val7" and so on. I can only assume that he tried "val2" to "val6" inclusive - somehow - and got no result he liked. :sigh:
