set 语句 将对象引用赋给变量或属性 你定义 pm为变量 却用set 当然是牛头不对马嘴。。Dim pm(0 To 2) As Double Dim pm1(0 To 2) As Double pm(0) = 0 pm(1) = 0 pm1(0) = 0 pm1(1) = 0 这样就好
f = Sheet1.cells(rows.count,a).End(xlDown).Row z = Sheet2.cells(rows.count,a).End(xlDown).Row

static void Main(string[] args){ 改成 protected void Page_Load(object sender, EventArgs e){
