Excel getting corrupt when created through Code C# - c#

I was trying to create an excel using Memory Stream. Here is the code I'm trying,
using (MemoryStream mem = new MemoryStream())
{
using (var sheetDocument = SpreadsheetDocument.Create(mem, SpreadsheetDocumentType.Workbook))
{
//// Add a WorkbookPart to the document.
WorkbookPart workbookpart = sheetDocument.AddWorkbookPart();
workbookpart.Workbook = new Workbook();
WorkbookStylesPart workbookstyle = workbookpart.AddNewPart<WorkbookStylesPart>();
workbookstyle.Stylesheet = this.GenerateStyleSheet();
workbookstyle.Stylesheet.Save();
//// Add a WorksheetPart to the WorkbookPart.
WorksheetPart worksheetPart = workbookpart.AddNewPart<WorksheetPart>();
worksheetPart.Worksheet = new Worksheet();
Columns cols = new Columns();
Column col = new Column();
col.BestFit = true;
col.CustomWidth = true;
col.Width = 22.33;
col.Max = 13;
col.Min = 1;
cols.Append(col);
worksheetPart.Worksheet.Append(cols);
SheetData sheetData = new SheetData();
worksheetPart.Worksheet.Append(sheetData);
//// Add Sheets to the Workbook.
Sheets sheets = sheetDocument.WorkbookPart.Workbook.AppendChild<Sheets>(new Sheets());
//// Append a new worksheet and associate it with the workbook.
Sheet sheet = new Sheet() { Id = sheetDocument.WorkbookPart.GetIdOfPart(worksheetPart), SheetId = 1, Name = sheetName };
sheets.Append(sheet);
workbookpart.Workbook.Save();
List<string> columns = new List<string>();
foreach (DataColumn column in table.Columns)
{
columns.Add(column.ColumnName);
}
DocumentFormat.OpenXml.Spreadsheet.Row headerRow = this.CreateHeaderRow(columns);
sheetData.AppendChild(headerRow);
foreach (DataRow dataSetRow in table.Rows)
{
DocumentFormat.OpenXml.Spreadsheet.Row newRow = this.CreateDataRow(dataSetRow);
sheetData.AppendChild(newRow);
}
workbookpart.Workbook.Save();
var result = mem.ToArray();
System.IO.File.WriteAllBytes(fileName, result);
}
An excel file is getting created, but when I try to open it, I'm getting an error as bellow
If I press yes, it says
The workbook cannot be opened or repaired by Microsoft Excel because
it is corrupt
How can I fix this?

Thanks to #zaikhan's comment, I was able to fix my issue. When I closed the sheetDocument it worked.
using (MemoryStream mem = new MemoryStream())
{
using (var sheetDocument = SpreadsheetDocument.Create(mem, SpreadsheetDocumentType.Workbook))
{
//// Add a WorkbookPart to the document.
WorkbookPart workbookpart = sheetDocument.AddWorkbookPart();
workbookpart.Workbook = new Workbook();
WorkbookStylesPart workbookstyle = workbookpart.AddNewPart<WorkbookStylesPart>();
workbookstyle.Stylesheet = this.GenerateStyleSheet();
workbookstyle.Stylesheet.Save();
//// Add a WorksheetPart to the WorkbookPart.
WorksheetPart worksheetPart = workbookpart.AddNewPart<WorksheetPart>();
worksheetPart.Worksheet = new Worksheet();
Columns cols = new Columns();
Column col = new Column();
col.BestFit = true;
col.CustomWidth = true;
col.Width = 22.33;
col.Max = 13;
col.Min = 1;
cols.Append(col);
worksheetPart.Worksheet.Append(cols);
SheetData sheetData = new SheetData();
worksheetPart.Worksheet.Append(sheetData);
//// Add Sheets to the Workbook.
Sheets sheets = sheetDocument.WorkbookPart.Workbook.AppendChild<Sheets>(new Sheets());
//// Append a new worksheet and associate it with the workbook.
Sheet sheet = new Sheet() { Id = sheetDocument.WorkbookPart.GetIdOfPart(worksheetPart), SheetId = 1, Name = sheetName };
sheets.Append(sheet);
workbookpart.Workbook.Save();
List<string> columns = new List<string>();
foreach (DataColumn column in table.Columns)
{
columns.Add(column.ColumnName);
}
DocumentFormat.OpenXml.Spreadsheet.Row headerRow = this.CreateHeaderRow(columns);
sheetData.AppendChild(headerRow);
foreach (DataRow dataSetRow in table.Rows)
{
DocumentFormat.OpenXml.Spreadsheet.Row newRow = this.CreateDataRow(dataSetRow);
sheetData.AppendChild(newRow);
}
workbookpart.Workbook.Save();
sheetDocument.Close();
}
var result = mem.ToArray();
System.IO.File.WriteAllBytes(fileName, result);
}

C# OpenXML Changing Column Background

I have a code left by the previous developer. What I need to do is to change the background color and text color of the header columns in the Excel file. But I just couldn't. We use OpenXML. Heading columns are added as rows. I can't change background and text color of these header row. How can I change the background color of the cell interiors in the cell variable?

How to create Table inside Excel Sheet?

Use DocumentFormat.Openxml 2.8.1.
I try to create Excel Sheet and create Table inside it.
But when i do it - and try to open excel file - excel says that can not open and try to restore this file.
So, i create excel file:
var fStream = new FileStream(tempPathName, FileMode.Open, FileAccess.ReadWrite, FileShare.None, 1048, FileOptions.DeleteOnClose);
SpreadsheetDocument ssDoc = SpreadsheetDocument.Create(inputStream,
SpreadsheetDocumentType.Workbook);
Then , create sheet:
var tempPathName = Path.GetTempFileName();
WorkbookPart workbookPart = ssDoc.AddWorkbookPart();
workbookPart.Workbook = new Workbook();
Sheets sheets = ssDoc.WorkbookPart.Workbook.AppendChild<Sheets>(new Sheets());
WorksheetPart worksheetPart4 = workbookPart.AddNewPart<WorksheetPart>();
worksheetPart4.Worksheet = new Worksheet();
Worksheet workSheet4 = worksheetPart4.Worksheet;
var table = CreateTable1();
TableParts tableParts = new TableParts() { Count = (UInt32)1 };
TablePart tablePart = new TablePart() { Id = "rId" + 1 };
tableParts.Append(table);
tableParts.Append(tablePart);
workSheet4.AppendChild(tableParts);
Sheet sheet4 = new Sheet()
{
Id = ssDoc.WorkbookPart.GetIdOfPart(worksheetPart4),
SheetId = 4,
Name = "test"
};
sheets.Append(sheet4);
ssDoc.Close();
private Table CreateTable1()
{
// First, we create the table, its properties and we append it.
Table table = new Table();
TableProperties props = new TableProperties();
table.AppendChild<TableProperties>(props);
// Now we create a new layout and make it "fixed".
TableLayout tl = new TableLayout() { Type = TableLayoutValues.Fixed };
props.TableLayout = tl;
// Then we just create a new row and a few cells and we give them a width
var tr = new TableRow();
var tc1 = new TableCell();
var tc2 = new TableCell();
tc1.Append(new TableCellProperties(new TableCellWidth() { Type = TableWidthUnitValues.Dxa, Width = "2000" }));
tc2.Append(new TableCellProperties(new TableCellWidth() { Type = TableWidthUnitValues.Dxa, Width = "2000" }));
table.Append(tr);
return table;
}
So, how to create table in Excel sheet and insert data in table?
Thank you.
TableStyle class is what you`re looking for.
You actually have to create TableStyle and add it to your spreadsheet.
In CreateTable1(), TableProperties, TableLayout, TableRow, and TableCell are WordProcessing elements.
Instead, you will want to use code similar to this:
private void CreateTable2(SheetData sheetData)
{
var row1 = new Row(){ RowIndex = 1 };
sheetData.Append(row1);
var cell1 = new Cell();
cell1.DataType = CellValues.InlineString;
cell1.InlineString = new InlineString() { Text = new Text("Hello") };
row1.InsertAt(cell1, 0);
var cell2 = new Cell();
cell2.DataType = CellValues.InlineString;
cell2.InlineString = new InlineString() { Text = new Text("World") };
row1.InsertAt(cell2, 1);
}
Slightly modify the rest of your code to look like the following (most of which I borrowed from here).
var fStream = new FileStream(tempPathName, FileMode.Create);
SpreadsheetDocument ssDoc = SpreadsheetDocument.Create(fStream, SpreadsheetDocumentType.Workbook);
// Add a WorkbookPart to the document.
WorkbookPart workbookPart = ssDoc.AddWorkbookPart();
workbookPart.Workbook = new Workbook();
// Add a WorksheetPart to the WorkbookPart.
WorksheetPart worksheetPart = workbookPart.AddNewPart<WorksheetPart>();
worksheetPart.Worksheet = new Worksheet(new SheetData());
// Add Sheets to the Workbook.
Sheets sheets = ssDoc.WorkbookPart.Workbook.AppendChild<Sheets>(new Sheets());
// Append a new worksheet and associate it with the workbook.
Sheet sheet = new Sheet()
{
Id = ssDoc.WorkbookPart.GetIdOfPart(worksheetPart),
SheetId = 1,
Name = "mySheet"
};
sheets.Append(sheet);
// Get the sheetData cell table.
SheetData sheetData = worksheetPart.Worksheet.GetFirstChild<SheetData>();
CreateTable2(sheetData);
workbookPart.Workbook.Save();
ssDoc.Close();
fStream.Close();

Open XML: How to add rows and cell value after appending new sheet in existing Excel file using c#

I inserted/appended new sheet in existing Excel file using open XML but I am not able to add rows and cell values. Following is my code:
using (var workbook = SpreadsheetDocument.Open(excelFilePath, true))
{
var workbookPart = workbook.WorkbookPart;
var wb = workbookPart.Workbook;
int rowIndex = 0;
// Add a blank WorksheetPart.
WorksheetPart newWorksheetPart = workbook.WorkbookPart.AddNewPart<WorksheetPart>();
newWorksheetPart.Worksheet = new Worksheet(new SheetData());
Sheets sheets = workbook.WorkbookPart.Workbook.GetFirstChild<Sheets>();
string relationshipId = workbook.WorkbookPart.GetIdOfPart(newWorksheetPart);
// Get a unique ID for the new worksheet.
uint sheetId = 1;
if (sheets.Elements<Sheet>().Count() > 0)
{
sheetId = sheets.Elements<Sheet>().Select(s => s.SheetId.Value).Max() + 1;
}
// Give the new worksheet a name.
string sheetName = "Data";
// Append the new worksheet and associate it with the workbook.
Sheet dataSheet = new Sheet() { Id = relationshipId, SheetId = sheetId, Name = sheetName };
sheets.Append(sheet);
workbookPart.Workbook.Save();
var sharedStringPart = workbookPart.SharedStringTablePart;
var values = sharedStringPart.SharedStringTable.Elements<SharedStringItem>().ToArray();
Row headerRow = new Row();
Cell cell = new Cell();
cell.DataType = CellValues.String;
cell.CellValue = new CellValue("EmpId");
headerRow.AppendChild<Cell>(cell);
cell = new Cell();
cell.DataType = CellValues.String;
cell.CellValue = new CellValue("Name");
headerRow.AppendChild<Cell>(cell);
headerRow.AppendChild<Cell>(cell);
dataSheet.InsertAt<Row>(headerRow, rowIndex++);
workbookPart.Workbook.Save();
}
}
It's throwing an exception:
Non-composite elements do not have child elements.
When i got this error ("Non-composite elements do not have child elements.") was about my sheet object. I got the worng object to Apeend, so you need change the use .Append to something like that:
Worksheet worksheet = worksheetPart.Worksheet;
SheetData sheetData = worksheet.GetFirstChild<SheetData>();
sheetData.Append(row);
A Full Example
using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Create(tmp, SpreadsheetDocumentType.Workbook))
{
// Add a WorkbookPart to the document.
WorkbookPart workbookpart = spreadsheetDocument.AddWorkbookPart();
workbookpart.Workbook = new Workbook();
// Add a WorksheetPart to the WorkbookPart.
WorksheetPart worksheetPart = workbookpart.AddNewPart<WorksheetPart>();
worksheetPart.Worksheet = new Worksheet(new SheetData());
// Add Sheets to the Workbook.
Sheets sheets = spreadsheetDocument.WorkbookPart.Workbook.
AppendChild<Sheets>(new Sheets());
// Append a new worksheet and associate it with the workbook.
Sheet sheet = new Sheet()
{
Id = spreadsheetDocument.WorkbookPart.
GetIdOfPart(worksheetPart),
SheetId = 1,
Name = fileName,
};
sheets.Append(sheet);
var firstChild = sheet.FirstChild;
//sheet.Append(row);
Worksheet worksheet = worksheetPart.Worksheet;
SheetData sheetData = worksheet.GetFirstChild<SheetData>();
UInt32 rowIndex = 1;
var row = new Row() { RowIndex = rowIndex };
var firstNameCell = new Cell() { CellReference = "A" + rowIndex };
firstNameCell.CellValue = new CellValue("FirstName");
firstNameCell.DataType = CellValues.String;
row.Append(firstNameCell);
Cell lastNameCell = new Cell() { CellReference = "B" + rowIndex };
lastNameCell.CellValue = new CellValue("LastName");
lastNameCell.DataType = new EnumValue<CellValues>(CellValues.String);
row.Append(lastNameCell);
sheetData.Append(row);
workbookpart.Workbook.Save();
// Close the document.
spreadsheetDocument.Close();
}
