Dim i As New Int32
       Dim rpt As New CrystalReport7()
       i = 0
       rpt.SetDataSource(DataSet31)
       For i = 0 To Me.DataGridView1.SelectedRows.Count
           print.CrystalReportViewer1.SelectionFormula = String.Format("{{me.Table_1.id}} = '{i}'", Me.DataGridView1.SelectedCells(i).Value)

推荐答案

要传递多个值（是的，这就是你的意思希望），检查这些

使用多值参数为Crystal Reports选择记录 [ ^ ]

打印多个值或范围值的参数选择 [ ^ ]

To pass multiple values(yes, this's what do you want), check these
Using Multiple Value Parameters to Select Records for your Crystal Reports[^]
Printing Parameter Selections for Multiple or Range Values[^]
