所以我试图从excel导入创建数据表，然后用于其他事情。我知道电子表格表的名称，所以我在我的文档顶部创建了我的数据表：
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声明具有相同的名称
我有一个函数可以根据给定的工作表名称读取excel电子表格，所以我希望能够执行类似（伪代码）的操作：
foreach ExcelSheets{
Datatable = dt.ReadFunction()
}
DataTable是文件顶部声明的数据表。
所以我想对列表中的每个Sheet说，运行该函数并将结果分配给相应的数据表

答案 0 :(得分：1)
你必须使用Reflection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，它对我有效。
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);
}
}
