获取电子表格中列的值

Question

我正在使用devexpress，当我尝试使用以下代码获取电子表格单元格的值时：

  Workbook workbook = new Workbook();
  Column firstColumn_byName = columns["A"];

我收到以下错误：

  

当前上下文中不存在名称列

Answer 1

您尚未定义columns。

Workbook workbook = new Workbook();

// Access a collection of columns.
ColumnCollection columns = workbook.Worksheets[0].Columns;

// Access the first column by its unique name.
Column firstColumn_byName = columns["A"];
