asp.net中引用excel问题 - .NET技术 / ASP.NET

在本机调试时生成excel文件没有问题（http://localhost:4354/go），但是发布到网站后（注：仍然是本机做为服务器http://192.168.1.8/go , 192.168.1.8为本机ip）则没有任何反应，请高手指点，急等，如要加分还有

我的代码如下：

Function MakeExcel(ByRef TitleData As String, ByRef Data As System.Data.Odbc.OdbcDataReader, ByRef XCount As Short, ByRef FileName As String, ByRef FilePath As String) As Object

  Dim tFileName As Object
  Dim i, j As Integer

  Dim ex As New Microsoft.Office.Interop.Excel.Application
  Dim exwbook As Microsoft.Office.Interop.Excel.Workbook
  Dim xlSheet As Microsoft.Office.Interop.Excel.Worksheet

  tFileName = FileName + Format(Now, "yyyyMMddhhmmss") + ".xls"

  ex = New Microsoft.Office.Interop.Excel.Application
  ex.Visible = True
  xlSheet = Nothing
  exwbook = Nothing
  exwbook = ex.Workbooks.Add
  xlSheet = exwbook.Worksheets(1)

  xlSheet.Cells._Default(1, 1) = "id号"
  xlSheet.Cells._Default(1, 2) = "投资人"
  xlSheet.Cells._Default(1, 3) = "家庭地址"
  xlSheet.Cells._Default(1, 4) = "电话"
   
   
  xlSheet.Visible = True
