Format string at runtime

I'm creating a html table at runtime (no probs there), and I would like to be able to format the content in the cells at runtime by passing in a format string (ie currencies, decimals, decimal places etc)

for example, i want to achieve somethi开发者_如何转开发ng like this but to be able to pass in the format of the string with code as a string, ie "{0:c}" or "#,###,###"

ideally to be able to pass it into the ToString() method ( i can't do that but was wondering if there could be a clever way to achieve this?)

tblCell.Text = dt.Rows[i][j].ToString(#.##);

---

tblCell.Text = String.Format("{0:c}", dt.Rows[i][j])

and

tblCell.Text = String.Format("{0:#.##}", dt.Rows[i][j])

should work.

You can supply format strings to the columns in your GridView by setting the DataFormatString property of the column to something like this: “{0:d}”.

I always use this cheat sheet to find out things like these as the number of possibilities is simply to big to remember them all
