for i in number_of_tuples :
first_element = myList[i[0]]

你知道[list_element[tuple_element]]吗?但是,这似乎不是正确的方法.任何帮助将不胜感激.

我正在尝试使用DataTable.Merge()选项合并多个Excel文件
For Each fileName As String In Directory.GetFiles("C:\TEMP\.", "*.xls")
Dim connectionString As String = String.Format("Provider=Microsoft.Jet.OLEDB.4.0; data source={0}; Extended Properties=""Excel 8.0;HDR=NO;IMEX=1;""", fileName)
Dim adapter As New OleDbDataAdapter("SELECT * FROM [Sheet1$]", connectionString)
Dim ds As New DataSet
adapter.Fill(ds, "anyNameHere")
