尝试获取Excel表格中的“表格”列表

Question

我有一个有两个表格（选择数据并选择格式作为表格并赋予其名称）的Excel文档。

我想打开工作簿并获取文档中的所有表。

以下代码返回工作簿中的一堆节，但不返回特定的表。

这可能吗？

public partial class Form1 : Form 
{ 
    private DataSet _excelDataSet; 

    public Form1() 
    { 
     InitializeComponent(); 


     var filePath = "c:\\temp\\orderforms\\SampleOrder.xlsx"; 

     var tmpName = Path.GetTempFileName() + Path.GetExtension(filePath); 
     File.Copy(filePath, tmpName); 
     filePath = tmpName; 


     var excelReader = GetExcelDataReader(filePath, true); 
     excelReader.IsFirstRowAsColumnNames = true; 

     _excelDataSet = excelReader.AsDataSet(); 

    } 

    private static IExcelDataReader GetExcelDataReader(string path, bool isFirstRowAsColumnNames) 
    { 
     using (var fileStream = File.Open(path, FileMode.Open, FileAccess.Read)) 
     { 
      IExcelDataReader dataReader; 

      if (path.EndsWith(".xls")) 
       dataReader = ExcelReaderFactory.CreateBinaryReader(fileStream); 
      else if (path.EndsWith(".xlsx")) 
       dataReader = ExcelReaderFactory.CreateOpenXmlReader(fileStream); 
      else 
       throw new FileToBeProcessedIsNotInTheCorrectFormatException("The file to be processed is not an Excel file"); 

      dataReader.IsFirstRowAsColumnNames = isFirstRowAsColumnNames; 

      return dataReader; 
     } 
    } 

    private void btnLoadOrder_Click(object sender, EventArgs e) 
    { 

     DataTable dt1 = _excelDataSet.Tables[Convert.ToInt32(textBox1.Text)]; 

     dataGridView2.DataSource = dt1; 
     MessageBox.Show(dt1.TableName); 
    } 

}

Answer 1

var excel = new ExcelQueryFactory(); 
excel.FileName = "c:\\temp\\orderforms\\orderform.xlsx"; 
var order = from x in excel.NamedRange<SunglassesOrder>("Order") 
        where x.Qty!="" 
        select x; 
dataGridView1.DataSource = order.ToList();
