Hii
if String str=" ";
how to convert this to number?

2

Integer.parse(str) didn’t worked

3

convert.Int32(str) also didn’t worked

4

Why do you want to convert an empty space to number?

5

sometimes in UI either it will be given number , sometimes left blank or sometimes given zero

6

so check before converting it to number, If it is empty string. Only after that convert it or else directly pass the value without converting if its empty.

@KarthikBallary,

IsNumeric(“yourString”)

@KarthikBallary,

Try like this to convert it number by removing spaces,

yourString.Split({" "}, StringSplitOptions.RemoveEmptyEntries)
12

So the expression be like this
int_output = IF(IsNumeric(str_input.ToString),Convert.ToInt32(str_input.ToString),0)
Where int_output is a variable of type int32 and it will get the converted int32 number or either a 0 value to it

@KarthikBallary

Is it working @KarthikBallary

17

Need to check I will let you know.

if str=“” it will convert to 0?

18

Yah that would either
Like first it will check whether it is a number or not
If it has any numerical value it will convert that
If not if just the str variable has only “” then it will give 0 or if it’s not a numerical value then also it will give us 0

Cheers @KarthikBallary

It is working fine for first loop, second loop throwing error-Object reference not set to an instance of an object.

Fine
It means the input string variable has no value in it
Kindly validate that once using a writeline activity before this conversion so that we can see in the output panel whether it shows any value or not
Cheers @KarthikBallary
