将DataTable列表与string列表进行比较
所以我试图从Excel导入创build数据表然后用于其他事情。 我知道电子表格的名字，所以我在我的文档顶部创build了我的数据表：
private DataTable Version,Pi_PROCESSPi_PMLIFEPROFILE,PIAPPLICATION,PIRUGGEDISING,ELECTRONICCOMPONENT,HFANDRFCOMPONENTS,HYBRIDANDMULTICHIPMODULE,COTSBOARDS, VARIOUSSUBASSEMBLIES,PARTCOUNT, FAMILYCOUNT; 然后，当读取电子表格时，我将有一个列表和一个for循环，将spreadhseet名称分配给该列表
List<string>ExcelSheets = new List<string>();
Excel电子表格列表和数据表单具有相同的名称
我有一个函数读取Excel电子表格基于给定的表名，所以我想能够做一些像（伪代码）：
foreach ExcelSheets{ Datatable = dt.ReadFunction() }
使用DataTable作为文件顶部的声明数据表。
所以我想对列表中的每个表格说一声，运行函数并将结果赋给相应的数据表

你必须使用reflection来实现这一点
foreach(var sheetName in ExcelSheets) { var prop = this.GetType().GetField(sheetName, BindingFlags.NonPublic | BindingFlags.Instance); prop.SetValue(this, dt.ReadFunction()); }
我有我的Form1构造函数，它为我工作。
