如何设置于参数?

[lihuabiao]

我想调用以下过程,如何设该过程的"Page"参数?
Public Function GenerateFile(ByRef Page As System.Web.UI.Page, ByVal MyDataGrid As System.Web.UI.WebControls.DataGrid, ByVal FileName As String) As String

Dim resp As HttpResponse
Dim colCount As Integer = MyDataGrid.Columns.Count - 1
resp = Page.Response
resp.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312") '解决中文乱码之关键
.....

End Function
