Convert string to integer .asp classic

问题

I have the following code, comments detail what should happen:

averageNum = myArray2(0) 'assign variable
response.write(TypeName(averageNum)&"<br>") 'check var type: string as expected
averageNum = CInt(averageNum) 'convert to integer

When I run this is I get

Type mismatch: 'CInt'

I need to turn the variable into an integer as I need to perform calculations with it

回答1:

I would be checking that the value of myArray2(0) is an integer as you're expecting. Simple way to do this is using IsNumeric() which returns a Boolean value.

Something like this;

averageNum = myArray2(0) 'assign variable
'Check numeric value assume 0 if not numeric.
If Len(averageNum) > 0 And IsNumeric(averageNum) Then
  averageNum = CInt(averageNum) 
Else
  averageNum = 0
End If
