    This may seem a little wacky, but String.Format is generally used for formatting other types to a string. Strings themselves cannot really be formatted in any meaningful way. Perhaps you could explain your problem a little more, and then maybe someone can help you with a solution.

    So in my case I have a table which contains 6 colomns which corresponds to a code and its value, and this table contains the characteristics of this value with format.donc to read a file from the code and its value must be correctly formatted according to the table, so I need to specify the format in 10 alpha numeric, so how do this??

      I believe this should do it.

      myString = myString.PadLeft(10);

        If you want "10a" (as opposed to " a"), you would use

        myString = string.Format("10{0}", a);

          I would recommend a validation process. If you try to format the return you will get spurious results. Try using Regular Expressions to validate the value. ^[a-zA-Z0-9]{10}\z should do the job.

            It's unclear what you are asking; please provide "before" and "after" examples.

              myString = myString.PadLeft(10, '0');

              would keep it all-alphanumeric. :)

                  that fills with spaces, one could argue the result isn't all alphanumeric. :)
