问题描述
我有以下代码,注释详细说明了应该发生的情况:
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
当我运行时,我得到了
Type mismatch: 'CInt'
我需要将变量转换为整数,因为我需要使用它进行计算
I need to turn the variable into an integer as I need to perform calculations with it
推荐答案
我会检查 myArray2(0)
的值是否是你所期望的整数.执行此操作的简单方法是使用返回 Boolean
值的 IsNumeric()
.
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.
类似的东西;
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
