在vb.net中声明动态对象名称

Question

Dim rptDocument As New ReportDocument
If Request.QueryString("rpt") = "rptTest" Then
    rptDocument = New rptTest
ElseIf Request.QueryString("rpt") = "rptMain" Then
    rptDocument = New rptMain
ElseIf Request.QueryString("rpt") = "rptLast" Then
    rptDocument = New rptLast
...
End If

更改为

rptDocument = New Request.QueryString("rpt")

查询字符串数据将与对象名称匹配。如何动态声明这个变量？
