我已经定义了 httpclient 系统怎么还提示我 未定义类型 HttpClient ？
在 按钮的事件里发生的。 请高人指点, ~~~ 非常干西恩~~~~
Dim Book As New XLS.Book '定义一个Excel工作簿
Dim Sheet As XLS.Sheet = Book.Sheets(0) '引用工作簿的第一个工作表
Dim t As Table = Tables("wuliu")
Dim pic = t.Current("pic")
Dim hc As New HttpClient(pic)
Dim dt As Date = hc.GetData()
MessageBox.Show(dt)
If dt !=Null Then
Dim wr As net.WebRequest = net.WebRequest.Create(pic)
End If
Dim res As net.WebResponse= wr.GetResponse
Dim bmp As New Bitmap(res.GetResponseStream)
For i As Integer = 0 To 9 '向工作表的单元格中设置值
Sheet(i, 1).Value = (i + 1) * 10
Sheet(i, 2).Value = (i + 1) * 100
Sheet(i, 3).Value = (i + 1) * 1000
Sheet(i,0).Value = New XLS.Picture(bmp,6,1,68,78)
Sheet.Rows(i).Height = 80
Next
Book.Save("c:\test.xls") '保存工作簿
Dim Proc As New Process '打开工作簿
Proc.File = "c:\test.xls"
Proc.Start()
