标题Re: [.NET] Unable to cast object of type
时间Sat Jan 15 19:27:16 2011
※ 引述《mindscold (喵)》之铭言：
: Dim Table As DataTable = DirectCast(Me.myBindingSource.DataSource, DataTable)
: 并且出现以下的错误讯息：
: "Unable to cast object of type 'PICData.PICSettingDataSet' to type
: 'System.Data.DataTable'
: 请问为什麽datasource也是table却不能转换成datatable？
: 该怎麽改才是对的呢？谢谢
Try
Dim ds as DataSet = CType(Me.myBindingSource.DataSource, DataSet)
Catch ex As Exception
MsgBox(ex.Message)
End Try
Dim dt1 as DataTable = ds.Tables(0)

1F：→ horngsh:忘了Scope限制,请把ds改放在Try 上方,如Dim ds as DataSet 01/15 19:29
2F：→ horngsh:然後Try下面用ds = CType(....) 01/15 19:29
3F：推 mindscold:感谢，我马上试试 01/17 08:23
