'申明变量时可以用逗号分隔

Dim st As Date = Now(),et As Date,sp As New TimeSpan

Dim cmd As New SQLCommand,dt As DataTable

cmd.ConnectionName = Args(2)

cmd.CommandText = "Sel ect * From {" & Args(0) & "}"

dt = cmd.ExecuteReader() '通过SQL命令生成临时表(DataTable)

Dim app As New MSExcel.Application

Dim wb As MSExcel.WorkBook = app.WorkBooks.Add()

'获取工作簿中的第一张工作表

Dim ws As MSExcel.WorkSheet = wb.WorkSheets(1)

Dim j As Integer = 1

'将临时表的列名写入工作表的第一行

For Each dc As DataCol In dt.DataCols

    ws.Cells(1,j) = dc.Name:j += 1

Next

'通过双循环将临时表的数据写入工作中

For i As Long = 0 To dt.DataRows.Count - 1:j = 1

    For Each dc As DataCol In dt.DataCols

        ws.Cells(i+2,j) = dt.DataRows(i)(dc.Name):j += 1

    Next

Next

'冒号可以分隔多条短语句

wb.SaveAs(Args(1)):app.Quit():et = Now():sp = et - st

MessageBox.Show("开销: " & sp.TotalSeconds & " 秒","提示",MessageBoxButtons.YesNo,MessageBoxIcon.Information)
