在 Microsoft Excel 中，按字母顺序或数值顺序排列数据，使得人工分析数据成为可能。 IronXL使排序Excel Ranges在C#和VB.NET中变得极其简单。
在选定的范围或列上使用SortDescending方法，以适当的顺序应用排序。 不过，SortByColumn方法需要两个参数：第一个输入是要排序的列，第二个输入是排序顺序。
using IronXL;
WorkBook workBook = WorkBook.Load("sample.xlsx");
WorkSheet workSheet = workBook.DefaultWorkSheet;
// Select a range
var range = workSheet["A1:D20"];
// Select a column(B)
var column = workSheet.GetColumn(1);
// Sort the range in ascending order (A to Z)
range.SortAscending();
// Sort the range by column(C) in ascending order
range.SortByColumn("C", SortOrder.Ascending);
// Sort the column(B) in descending order (Z to A)
column.SortDescending();
workBook.SaveAs("sortExcelRange.xlsx");
Imports IronXL
Dim workBook As WorkBook = WorkBook.Load("sample.xlsx")
Dim workSheet As WorkSheet = workBook.DefaultWorkSheet
' Select a range
Dim range = workSheet("A1:D20")
' Select a column(B)
Dim column = workSheet.GetColumn(1)
' Sort the range in ascending order (A to Z)
range.SortAscending()
' Sort the range by column(C) in ascending order
range.SortByColumn("C", SortOrder.Ascending)
' Sort the column(B) in descending order (Z to A)
column.SortDescending()
workBook.SaveAs("sortExcelRange.xlsx")
