Convert string to integer

[Shaileshsharma]

Hi,
I have a value in string type variable ,i want to convert the string type into integer.This is my sample code

int s1;
string s2;
int s3;

if (ds.Tables[0].Rows.Count > 0)
{
s1 = ds.Tables[0].Rows.Count;
for (int i = 0; i < s1; i++)
s2=(ds.Tables[0].Rows[i][0]).ToString();


s3 = Convert.ToInt32("s2");


i use also system.int32.parse

but in both case the error is coming "Input string was not in a correct format."

please help me to find out the answer of this problem

Thanks,

Really silly bug.
You're trying to convert the string "s2" to an integer.
It should be

s3 = Convert.ToInt32(s2); // no quotes there

Do no use quotes in this line
s3 = Convert.ToInt32("s2");

use:
s3 = Convert.ToInt32(s2);

and check ur variable does not contain any alphab. or any other symbols, only numeric values can be converted.

it IS possible to parse other strings if you need to, check into System.Globalization.NumberStyles if you want to see more examples of how to parse the string "$1,000.00" or a hex number like "A23B"
