C#创建Excel多级分组的方法
概述
在使用C#操作Excel表格时,有时需要将数据按多个字段进行分组展示,这就需要使用Excel中的多级分组功能。本文将介绍如何使用C#创建Excel多级分组,并提供两个示例说明。
示例说明
示例1:使用C#创建Excel多级分组
下面是一个示例代码,演示如何使用C#创建Excel多级分组。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Office.Interop.Excel;
namespace Demo
{
class Program
{
static void Main(string[] args)
{
// 创建Excel对象
Application excel = new Application();
// 创建工作簿
Workbook workbook = excel.Workbooks.Add();
// 获取第一个工作表
Worksheet worksheet = (Worksheet)workbook.Worksheets[1];
// 写入表格数据
worksheet.Cells[1, 1] = "部门";
worksheet.Cells[1, 2] = "姓名";
worksheet.Cells[1, 3] = "成绩";
worksheet.Cells[2, 1] = "技术部";
worksheet.Cells[2, 2] = "张三";
worksheet.Cells[2, 3] = 80;
worksheet.Cells[3, 1] = "技术部";
worksheet.Cells[3, 2] = "李四";
worksheet.Cells[3, 3] = 90;
worksheet.Cells[4, 1] = "市场部";
worksheet.Cells[4, 2] = "王五";
worksheet.Cells[4, 3] = 85;
worksheet.Cells[5, 1] = "市场部";
worksheet.Cells[5, 2] = "赵六";
worksheet.Cells[5, 3] = 95;
// 设置分组字段
Range range = worksheet.Range["A1:C5"];
range.Select();
// 分组
worksheet.Rows.Group(start: Type.Missing, end: Type.Missing, byRow: Type.Missing, byColumn: Type.Missing, total: Type.Missing);
// 设定多级分组
worksheet.Outline.SummaryRow = XlSummaryRow.xlSummaryAbove;
range.AutoFilter();
range.Sort(Key1: range.Columns[3], Order1: XlSortOrder.xlDescending, Orientation: XlSortOrientation.xlSortColumns,
Header: XlYesNoGuess.xlYes, MatchCase: false, SortMethod: XlSortMethod.xlStroke, DataOption1: XlSortDataOption.xlSortNormal);
int i;
for (i = 1; i <= 2; i++)
{
range.Subtotal(GroupBy: i, Function: XlConsolidationFunction.xlSum, TotalList: System.Array.CreateInstance(typeof(int), i + 1), Replace: true,
PageBreaks: false, SummaryBelowData: XlSummaryRow.xlSummaryBelow);
}
// 保存并关闭Excel对象
workbook.SaveAs("Demo.xlsx");
workbook.Close();
excel.Quit();
}
}
}
上述代码首先创建Excel对象,然后创建工作簿和工作表,并写入表格数据。接着,我们使用Range对象选中整个表格,并调用Rows.Group方法进行分组。最后,使用Subtotal方法实现多级分组。
示例2:使用C#创建Excel多级分组(带合并单元格)
下面是一个示例代码,演示如何使用C#创建Excel多级分组,并在分组后的每个小组内部将第一列合并为一个单元格。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Office.Interop.Excel;
namespace Demo
{
class Program
{
static void Main(string[] args)
{
// 创建Excel对象
Application excel = new Application();
// 创建工作簿
Workbook workbook = excel.Workbooks.Add();
// 获取第一个工作表
Worksheet worksheet = (Worksheet)workbook.Worksheets[1];
// 写入表格数据
worksheet.Cells[1, 1] = "部门";
worksheet.Cells[1, 2] = "姓名";
worksheet.Cells[1, 3] = "成绩";
worksheet.Cells[2, 1] = "技术部";
worksheet.Cells[2, 2] = "张三";
worksheet.Cells[2, 3] = 80;
worksheet.Cells[3, 1] = "技术部";
worksheet.Cells[3, 2] = "李四";
worksheet.Cells[3, 3] = 90;
worksheet.Cells[4, 1] = "市场部";
worksheet.Cells[4, 2] = "王五";
worksheet.Cells[4, 3] = 85;
worksheet.Cells[5, 1] = "市场部";
worksheet.Cells[5, 2] = "赵六";
worksheet.Cells[5, 3] = 95;
// 设置分组字段
Range range = worksheet.Range["A1:C5"];
range.Select();
// 分组
worksheet.Rows.Group(start: Type.Missing, end: Type.Missing, byRow: Type.Missing, byColumn: Type.Missing, total: Type.Missing);
// 设定多级分组
worksheet.Outline.SummaryRow = XlSummaryRow.xlSummaryAbove;
range.AutoFilter();
range.Sort(Key1: range.Columns[3], Order1: XlSortOrder.xlDescending, Orientation: XlSortOrientation.xlSortColumns,
Header: XlYesNoGuess.xlYes, MatchCase: false, SortMethod: XlSortMethod.xlStroke, DataOption1: XlSortDataOption.xlSortNormal);
int i;
for (i = 1; i <= 2; i++)
{
range.Subtotal(GroupBy: i, Function: XlConsolidationFunction.xlSum, TotalList: System.Array.CreateInstance(typeof(int), i + 1), Replace: true,
PageBreaks: false, SummaryBelowData: XlSummaryRow.xlSummaryBelow);
// 合并单元格
Range deptColumn = worksheet.Range[worksheet.Cells[range.Row, 1], worksheet.Cells[range.Row + range.Rows.Count - 1, 1]];
deptColumn.Merge();
}
// 保存并关闭Excel对象
workbook.SaveAs("Demo.xlsx");
workbook.Close();
excel.Quit();
}
}
}
上述代码结构与示例1相同,只是在分组后的每个小组内部增加了一个合并单元格的操作。我们使用Range对象选中每个小组的第一列,并调用Merge方法进行单元格合并。
