Compare DataTable list to String List
本文关键字：String List to list DataTable Compare | 更新日期: 2023-09-27 18:13:18
所以我试图从excel导入创建数据表，然后用于其他事情。我知道电子表格的名称，所以我在文档的顶部创建了数据表:
private DataTable Version,Pi_PROCESSPi_PMLIFEPROFILE,PIAPPLICATION,PIRUGGEDISING,ELECTRONICCOMPONENT,HFANDRFCOMPONENTS,HYBRIDANDMULTICHIPMODULE,COTSBOARDS, VARIOUSSUBASSEMBLIES,PARTCOUNT, FAMILYCOUNT;
当读取电子表格时，我有一个列表和一个for循环，将电子表格名称分配给该列表
List<string>ExcelSheets = new List<string>();
excel电子表格列表和数据表声明具有相同的名称
我有一个基于给定表名读取excel电子表格的函数，所以我希望能够做一些像(伪代码):
foreach ExcelSheets{
Datatable = dt.ReadFunction()
}
，其中DataTable是文件顶部声明的数据表。
所以我想说对于列表中的每个Sheet，运行函数并将结果赋值给相应的数据表

你必须使用反射来实现这个
foreach(var sheetName in ExcelSheets)
{
var prop = this.GetType().GetField(sheetName, BindingFlags.NonPublic | BindingFlags.Instance);
prop.SetValue(this, dt.ReadFunction());
}
我在我的Form1构造函数中有以下内容，它为我工作。
private DataTable Version, Pi_PROCESSPi_PMLIFEPROFILE, PIAPPLICATION, PIRUGGEDISING, ELECTRONICCOMPONENT, HFANDRFCOMPONENTS, HYBRIDANDMULTICHIPMODULE, COTSBOARDS, VARIOUSSUBASSEMBLIES, PARTCOUNT, FAMILYCOUNT;
List<string> ExcelSheets = new List<string>();
public Form1()
{
InitializeComponent();
var list = new string[] { "Version", "Pi_PROCESSPi_PMLIFEPROFILE", "PIAPPLICATION", "PIRUGGEDISING", "ELECTRONICCOMPONENT", "HFANDRFCOMPONENTS", "HYBRIDANDMULTICHIPMODULE", "COTSBOARDS", "VARIOUSSUBASSEMBLIES", "PARTCOUNT", "FAMILYCOUNT" };
ExcelSheets= list.ToList();
foreach(var sheet in ExcelSheets)
{
var prop = this.GetType().GetField(sheet, BindingFlags.NonPublic | BindingFlags.Instance);
Debug.WriteLine(prop.FieldType);
Debug.WriteLine(prop != null);
}
}
