忽略使用 ExcelDataReader 加载到数据集中的特定列？

Question

我正在使用 ExcelDataReader to load the data into an DataSet, which will be eventually be loaded into an DataGrid in WPF. I have specific columns with headers as SLNO and FY which I don't want to include. How can I ignore those columns using FilterColumn mentioned here?

Answer 1

如果要在显示的时候过滤这些列，使用下面的代码：

    gridview.Columns["ColumnName"].Visible = false;

或：

   DataView view = new DataView(DataSet.table[0]);
   DataTable table2 = view.ToTable(false, "FirstColumn", "SecondColumn",      "ThirdColumn");

   GridDataView.DataSource = Table2;

Answer 2

您可以处理 AutoGeneratingColumn 事件：

private void DataGrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
{
    e.Cancel = e.PropertyName == "SLNO" || e.PropertyName == "FY";
}

Answer 3

这就是 FilterColumn 的工作方式

using (var stream = File.Open(filePath, FileMode.Open, FileAccess.Read))
{
    List<string> skipColumns = new List<string> { "SLNO", "FY" };
    using (var reader = ExcelReaderFactory.CreateReader(stream))
    {
        var result = reader.AsDataSet(new ExcelDataSetConfiguration()
        {
            ConfigureDataTable = (tableReader) => new ExcelDataTableConfiguration()
            {
                UseHeaderRow = true,
                FilterColumn = (rowReader, columnIndex) =>
                {
                    return !skipColumns.Contains((rowReader[columnIndex].ToString()));
                }
            }
        });
    }
}
