Your answer would still be ToString.

Solution 2

Hi,

You can use StringBuilder.ToString() to output the value.

Please see the below sample .

StringBuilder sb = new StringBuilder("This is test");
           sb.Append("Apple");
           sb.ToString();

Thanks

Thanks for the response. A little change in the question. I need to select the current data from stringbuilder when selecting multiple values from database.

Solution 1

Yes. Just examine the

.ToString ()

method

Not sure what you mean...post the code snippet you're having a problem with

[no name] 19-Oct-14 8:19am

And format your code so it's readable. And actually tell us what the real problem is. The answer to update #3 is still ToString.

CHill60 19-Oct-14 12:08pm

I still don't get the problem. Which specific line is the problem..."snippet" implies just post the relevant code

Thanks for response. I solved it myself
