从Excel读取特定区域到2D阵列

Question

我在Excel中有一个表格，我想在excel中将选定区域导入2D数组。它必须与C＃中的2D数组相同。我有一张照片，请看一下。我想将该区域导入int array[81,81]：

Answer 1

您可以使用GemBox.Spreadsheet库（您可以使用其免费版本来实现此目的）。

以下是您可以使用的示例：

ExcelFile workbook = ExcelFile.Load("guncellenmis.xlsx");
ExcelWorksheet worksheet = workbook.Worksheets.ActiveWorksheet;

int count = 81;
int[,] data = new int[count, count];

// Get range from "C2" to "CE82".
CellRange range = worksheet.Cells.GetSubrangeRelative(1, 2, count, count);
// Or you can retrieve the required range differently, like:
//CellRange range = worksheet.Cells.GetSubrangeRelative("C2:CE82");
//CellRange range = worksheet.Cells.GetSubrangeRelative("C2", "CE82");
// etc.

for (int row = 0; row < range.Height; ++row)
    for (int column = 0; column < range.Width; ++column)
        data[row, column] = range[row, column].IntValue;

编辑： 您是否有理由将excel文件导出为2D数组而不是DataTable 您可以将所需数据作为DataTable进行检索，如下所示：

ExcelFile workbook = ExcelFile.Load("guncellenmis.xlsx");
ExcelWorksheet worksheet = workbook.Worksheets.ActiveWorksheet;

DataTable table = worksheet.CreateDataTable(
    new CreateDataTableOptions("C2", 81, 81));
