Excel .NET管理组件Spire.XLS数据处理系列教程：如何数据排序和数据验证
Spire.XLS for .NET 是一款专业的 .NET Excel 组件， 它可以用在各种.NET 框架中，包括 .NET Core、ASP.NET 和 Windows Forms 等相关的.NET 应用程序。在Excel表格中单元格也是我们经常会使用到的格式，这时我们如何使用Spire.XLS来完成呢？这就是本系列教程将给大家详细讲解的。>>下载Spire.XLS最新试用版
C# Excel 数据排序
我们可以对Excel中的数据进行排序，Spire.XLS支持以下三种排序方式：
- 基于单元格的值
- 基于单元格的背景颜色
- 基于单元格的字体颜色
基于单元格的值
//创建Workbook实例Workbook workbook = new Workbook();//加载Excel文档workbook.LoadFromFile(@"SortData.xlsx");//获取第一个工作表Worksheet worksheet = workbook.Worksheets[0];//指定需要排序的列索引以及排序的方式 （基于单元格的值）SortColumn column = workbook.DataSorter.SortColumns.Add(0, SortComparsionType.Values, OrderBy.Descending);//排序是否包含标题（默认第一个数据为标题，不会对它进行排序）workbook.DataSorter.IsIncludeTitle = false;//指定要排序的单元格范围并进行排序workbook.DataSorter.Sort(worksheet.Range["A2:A9"]);//保存文档workbook.SaveToFile(@"SortByValues.xlsx", ExcelVersion.Version2010);
基于单元格的背景颜色
//创建Workbook实例Workbook workbook = new Workbook();//加载Excel文档workbook.LoadFromFile(@"SortData.xlsx");//获取第二个工作表Worksheet worksheet = workbook.Worksheets[1];//指定需要排序的列索引以及排序的方式 （基于单元格的背景颜色）SortColumn column = workbook.DataSorter.SortColumns.Add(0, SortComparsionType.BackgroundColor, OrderBy.Top);//指定背景颜色column.Color = Color.Red;//排序是否包含标题（默认第一个数据为标题，不会对它进行排序）workbook.DataSorter.IsIncludeTitle = false;//指定要排序的单元格范围并进行排序workbook.DataSorter.Sort(worksheet.Range["A2:A8"]);//保存文档workbook.SaveToFile(@"SortByCellColor.xlsx", ExcelVersion.Version2010);
基于单元格的字体颜色
//创建Workbook实例Workbook workbook = new Workbook();//加载Excel文档workbook.LoadFromFile(@"SortData.xlsx");//获取第三个工作表Worksheet worksheet = workbook.Worksheets[2];//指定需要排序的列索引以及排序的方式 （基于单元格的字体颜色） SortColumn column = workbook.DataSorter.SortColumns.Add(0, SortComparsionType.FontColor, OrderBy.Bottom);//指定字体颜色column.Color = Color.Red;//排序是否包含标题（默认第一个数据为标题，不会对它进行排序）workbook.DataSorter.IsIncludeTitle = false;//指定要排序的单元格范围并进行排序workbook.DataSorter.Sort(worksheet.Range["A2:A8"]);//保存文档workbook.SaveToFile(@"SortByFontColor.xlsx", ExcelVersion.Version2010);
C# 设置 Excel 数据验证/数据有效性
Spire.XLS 支持的数据验证类型：
- 数字验证
- 序列验证
- 文本长度验证
- 时间验证
- 日期验证
- 自定义验证
数字验证
Validation numberValidation = sheet.Range["C1"].DataValidation;//整数验证numberValidation.AllowType = CellDataType.Integer;//小数验证//numberValidation.AllowType = CellDataType.Decimal;//限制输入1-10之间的整数numberValidation.CompareOperator = ValidationComparisonOperator.Between;numberValidation.Formula1 = "1";numberValidation.Formula2 = "10";
序列验证
Validation listValidation = sheet.Range["C2"].DataValidation;listValidation.Values = new string[] { "销售", "人力资源", "研发", "财务" };
文本长度验证
Validation txtLengthvalidation = sheet.Range["C3"].DataValidation;txtLengthvalidation.AllowType = CellDataType.TextLength;txtLengthvalidation.CompareOperator = ValidationComparisonOperator.Between;//限制输入的文本长度在1-5之间txtLengthvalidation.Formula1 = "1";txtLengthvalidation.Formula2 = "5";
时间验证
Validation timeValidation = sheet.Range["C4"].DataValidation;timeValidation.AllowType = CellDataType.Time;timeValidation.CompareOperator = ValidationComparisonOperator.Between;//限制输入时间在00.00到24.00之间timeValidation.Formula1 = "00.00";timeValidation.Formula2 = "24.00";
日期验证
Validation dateValidation = sheet.Range["C5"].DataValidation;dateValidation.AllowType = CellDataType.Date;dateValidation.CompareOperator = ValidationComparisonOperator.Between;//限制输入日期在2016/5/10到2017/5/10之间dateValidation.DateTime1 = new DateTime(2016, 5, 10);dateValidation.DateTime2 = new DateTime(2017, 5, 10);
自定义验证
Validation customValidation = sheet.Range["C6"].DataValidation;customValidation.AllowType = CellDataType.User;customValidation.Formula1 = "=A1>10";
