[英]Compare DataTable list to String List
因此，我試圖從excel導入創建數據表，然后將其用於其他用途。 我知道電子表格的名稱，因此我在文檔頂部創建了數據表：
private DataTable Version,Pi_PROCESSPi_PMLIFEPROFILE,PIAPPLICATION,PIRUGGEDISING,ELECTRONICCOMPONENT,HFANDRFCOMPONENTS,HYBRIDANDMULTICHIPMODULE,COTSBOARDS, VARIOUSSUBASSEMBLIES,PARTCOUNT, FAMILYCOUNT;
然后，當讀取電子表格時，我有一個列表和一個for循環，該電子表格為該列表分配了擴展名
List<string>ExcelSheets = new List<string>();
Excel電子表格列表和數據表聲明具有相同的名稱
我有一個功能，可以根據給定的工作表名稱讀取excel電子表格，因此我希望能夠執行以下操作（偽代碼）：
foreach ExcelSheets{
Datatable = dt.ReadFunction()
}
DataTable是文件頂部聲明的數據表。
因此，我想對列表中的每個工作表運行該函數並將結果分配給相應的數據表

您必須使用反射來實現這一目標
foreach(var sheetName in ExcelSheets)
{
var prop = this.GetType().GetField(sheetName, BindingFlags.NonPublic | BindingFlags.Instance);
prop.SetValue(this, dt.ReadFunction());
}
我在Form1構造函數中有關注者，它對我有用。
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);
}
}
如何將數據表轉換為列表 <string> 然后將其與文本框值進行比較？
