如何在不使用存储过程等的情况下通过Ado.net从模式中查找表名？

I am trying to read data from excel files using datatable.

我试图使用datatable从excel文件中读取数据。

The command "select * from [Sheet1$]" works fine but if the excel file has sheet with different name it gives error.

命令“select * from [Sheet1 $]”工作正常但如果excel文件具有不同名称的工作表,则会出错。

So now I need know how can I find the table names available in a schema using ADO.Net.

所以现在我需要知道如何使用ADO.Net找到模式中可用的表名。

Following Function will return the table name at the given position(eg, excel sheet) or return blank

以下函数将返回给定位置的表名(例如,excel表)或返回空白

Private Function GetTableName(ByVal ConnectionString As String, ByVal TableNumber As Integer) As String
    Dim i As Integer
    Dim dtXlsSchema As DataTable
    Dim myConn As New OleDbConnection
    myConn.ConnectionString = ConnectionString
    myConn.Open()
    dtXlsSchema = myConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, _
                      New Object() {Nothing, Nothing, Nothing, "TABLE"})


    If TableNumber > dtXlsSchema.Rows.Count Then
        Return ""
    Else
        Return dtXlsSchema.Rows(TableNumber - 1).Item("Table_Name").ToString
    End If
End Function
