Hi Enos,
You can use either intTryParse or Int16Converter class to achieve this
if(new Int16Converter().IsValid(Selected_List.SelectedItems[0].SubItems[0].Text.ToString()))
{
int userid = Convert.ToInt32(Selected_List.SelectedItems[0].SubItems[0].Text.ToString()
}
else
{
// Message
}
Regards,

int userid;
bool isValid = int.TryParse(Selected_List.SelectedItems[0].SubItems[0].Text, out userid);
if (isValid)
{
_imageId = userid;
}
else
{
// perhaps issue some warning to user
}

Try to check what are you actually trying to parse:
Console.WriteLine(Selected_List.SelectedItems[0].SubItems[0].Text)
EnosPosted Dec 2, 2014, 4:42 AM
_imageId = userid;
Use of unassigned local variable 'userid'

Check what you are getting for Selected_List.SelectedItems[0].SubItems[0].Text.
It may contain something that can not be INT,further
Text property itself of type 'string',.Tostring() is not required so change
Convert.ToInt32(Selected_List.SelectedItems[0].SubItems[0].Text.ToString());
to
Convert.ToInt32(Selected_List.SelectedItems[0].SubItems[0].Text);

int result = int.MinValue;
int userid;
int.TryParse(Selected_List.SelectedItems[0].SubItems[0].Text, out result);
if (result != int.MinValue)
userid = result;

it means that Selected_List.SelectedItems[0].SubItems[0].Text does not contains a value that can be converted to int.
so user
