Aspose Cells. Get rows by group - aspose

Question

How can I read rows by group using Aspose?
example

Answer 1

See the following sample code using Aspose.Cells for your reference:
e.g.
Sample code:
//Loading the file
Workbook book = new Workbook("e:\\test2\\Bk_readgrouped.xlsx");
//Get the first worksheet in the workbook
Worksheet sheet = book.Worksheets[0];
int maxRow = sheet.Cells.MaxDataRow;
int maxCol = sheet.Cells.MaxDataColumn;
int chk = 0;
bool pname = false;
Console.WriteLine("Retrieving each group's data");
for (int i = 0; i <= maxRow; i++)
{
int rowOutlineLevel = sheet.Cells.GetGroupedRowOutlineLevel(i);
if (rowOutlineLevel > 0)
{
pname = true;
if (pname== true & chk != rowOutlineLevel)
{
Console.WriteLine("\n");
Console.WriteLine("Group:" + rowOutlineLevel);
pname = false;
chk = rowOutlineLevel;
}
for (int j = 0; j <= maxCol; j++)
{
Console.Write(sheet.Cells[i, j].StringValue + "\t");
}
Console.WriteLine();
}
}
Hope, this helps a bit.

Answer 2

This works for me:
public virtual void ProcessExcelSheetTree (Worksheet Excelsheet, int current_level)
{
int current_row = 1;
int maxRow = Excelsheet.Cells.MaxDataRow;
int firstGroupIndex = 0;
while(Excelsheet.Cells[current_row, 0].StringValue != "")
{
var currentRow = Excelsheet.Cells.Rows[current_row];
if(currentRow.GroupLevel == current_level)
{
string targetName = Excelsheet.Cells[current_row, 0].StringValue;
Console.WriteLine(targetName);
firstGroupIndex = currentRow.Index;
for (int i = firstGroupIndex + 1; i <= maxRow; i++)
{
if(Excelsheet.Cells.Rows[i].GroupLevel > current_level)
{
string subTargetName = Excelsheet.Cells[i, 0].StringValue;
Console.WriteLine(" - " + subTargetName);
}
else
{
break;
}
}
}
current_row++;
}
}
