Formatting C# String

Question

I would like to print out information about products to the console line, and the code I have that does it is this:

const string format = "[PRODUCT_ID] {0, -10} | [SIZE] {1, -10} | [PRICE] {2, -10}"
foreach (DataRow row in productTable.Rows)
{
    Console.WriteLine(string.Format(format, row["PRODUCT_ID"], row["SIZE"], row["PRICE"]));
}

Ideally, I would like all the " | " to be lined up for the expected output to be:

[PRODUCT_ID] 25439  | [SIZE] XS | [PRICE] 34.55 USD

[PRODUCT_ID] 25438  | [SIZE] XL | [PRICE] 27.99 USD

[PRODUCT_ID] 142367 | [SIZE] S  | [PRICE] 27.99 USD

[PRODUCT_ID] 352344 | [SIZE] M  | [PRICE] 12.50 USD

But, in reality, the actual output in the console looks like:

[PRODUCT_ID] 25439 | [SIZE] XS | [PRICE] 34.55 USD

[PRODUCT_ID] 25438 | [SIZE] XL | [PRICE] 27.99 USD

[PRODUCT_ID] 142367 | [SIZE] S | [PRICE] 27.99 USD

[PRODUCT_ID] 352344 | [SIZE] M | [PRICE] 12.50 USD

Answer 1

const string format = "[PRODUCT_ID] {0} | [SIZE] {1} | [PRICE] {2}";
foreach (DataRow row in productTable.Rows)
{
    Console.WriteLine(string.Format(format, 
        row["PRODUCT_ID"].PadRight(10, ' '),
        row["SIZE"].PadRight(10, ' '),
        row["PRICE"].PadRight(10, ' ')));
}
