As the error message has already suggested you, the input is not correct and it can not be converted in to an int.

The best thing you can do is put a break-point on this line of code and then see what is the value you have selected comboBox1.

As per your comments, you are having values like 1-3, 5-6. If you want both values, you will have to have it in two different integer variables as shown below

string[] splitValues = Int32.Parse(comboBox1.SelectedItem.Split('-');
int firstValue = Int32.Parse(splitValues[0]);
int firstValue = Int32.Parse(splitValues[1]);

Hope that helps.

Hi Vinayak,

Please note that you as per your input you are conveting wrong value into integer.

Your combobox values are in the below form


to convet this value into integer you need to split these value into two part by separetor "-". And then you can convert this value into integer.

But the question is what value you want from this combobox.

i need 1-5 from combobox
digimanus 12-Nov-12 6:51am
do you use a multiselect combobox?
Mohd. Mukhtar 12-Nov-12 6:35am
you can get this value from the combobox as below.
string selectedValue = comboBox1.SelectedItem.ToString();

But you can not convert it directly into integer.

Remove all non-int characters from the string you are converting. If you have a ComboBox item which contains non-int characters but you need the int part then use a character array and passing the character array(of the string to be converted) remove the non-int characters and store the final string to be converted in a new variable. Then convert this new string you got containing only int-characters.
