I have a windows form application. In this application, I want to export some of my data in my form to excel. I have figured out how to create a Excel file and also stored some value to it. However one thing I am not sure is if there a way to add items to excel rows using a for loop (to figure out the rows and column according to how many data you have)? because it is pretty inefficient if you want to add a list of items let say 1000 items one by one.
For example: To add one item to specific cell one at a time, we can do something like this:
xlSomeDetail.Cells[1,1] = "Teacher Id";
xlSomeDetail.Cells[1,2] = "first name";
xlSomeDetail.Cells[1,3] = "Last Name";
xlSomeDetail.Cells[1,4] = "Email";
xlSomeDetail.Cells[1,5] = "Salary";
Now is there something like this if I want to do it without adding rows one by one?
//declare aRange variable
Excel.Range aRange;
aRange = (Excel.Range)xlSomeDetail.get_Range("A1", "M1");
//something like this? I am not sure
for (int i = 1; i< aRange.Rows; i++{
xlSomeDetail.Cell[1, i+ 1] = //somestring?
}
Are there any better method of doing this?

I'm generating an excel file in C# and excel file is format is as follows.
And Columns From C1 will be dynamic since there can be several dates.
And what I need to do is only allow editing for rows with Ctype
YYY
Is there any way to identify rows with Ctype = YYY
The code I use to generate excel is as follows
public string ExcelGenerator()
{
DataTable dt = GetDataTable();
var fileName = "ExcelFile";
var excelApp = new Application();
var workbooks = excelApp.Workbooks;
var excelWorkBook = workbooks.Add(XlWBATemplate.xlWBATWorksheet);
var sheets = excelWorkBook.Sheets;
var excelWorkSheet = sheets[1];
excelWorkSheet.Name = "ExcelFile";
int iCol = 1;
// Add column headings...
foreach (DataColumn c in dt.Columns)
{
excelWorkSheet.Cells[1, iCol] = c.ColumnName; ;
((Range)excelWorkSheet.Cells[1, iCol]).Interior.Color = ColorTranslator.ToOle(Color.DarkGray);
iCol++;
}
// for each row of data...
for (int j = 0; j < dt.Rows.Count; j++)
{
for (int k = 0; k < dt.Columns.Count; k++)
{
excelWorkSheet.Cells[j + 2, k + 1] = dt.Rows[j].ItemArray[k].ToString();
}
}
string fullpath = Path.Combine(excelPath, fileName);
if (File.Exists(fullpath))
{
try
{
File.Delete(fullpath);
}
catch (IOException e)
{
Console.Write(e.Message);
}
}
excelApp.DisplayAlerts = false;
excelWorkBook.SaveAs(fullpath, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookDefault, Type.Missing, Type.Missing, true, false, XlSaveAsAccessMode.xlNoChange, XlSaveConflictResolution.xlLocalSessionChanges, Type.Missing, Type.Missing);

Excel.Office.Interop don't allow range unprotection by programmatically.
For more information, you may visit this website.
https://msdn.microsoft.com/en-us/library/dkcs53f3.aspx
But if you use EPPlus library, you can do like Excel users.
if you allow selective editable column, excel requires sheet protection = true and some unprotected range.
(using EPPlus)
excelWorkSheet.Protection.IsProtected = true;
excelWorkSheet.ProtectedRanges.Add("editable", new ExcelAddress("B"));
Hi i try to get better with the c# excel stuff. Right now i try to select some values from an existing excelsheet. For Example: From B4 to C16. So i can replace the values with something else but i dont get it to work.
This is my little method:
public void writeExcelFile()
{
string path = #"C:\Users\AAN\Documents\Visual Studio 2015\Projects\WorkWithExcel\WorkWithExcel\bin\Debug\PROJEKTSTATUS_GESAMT_neues_Layout.xlsm";
oXL = new Excel.Application();
oXL.Visible = true;
oXL.DisplayAlerts = false;
mWorkBook = oXL.Workbooks.Open(path, 0, false, 5, "", "", false, Excel.XlPlatform.xlWindows, "", true, false, 0, true, false, false);
//Get all the sheets in the workbook
mWorkSheets = mWorkBook.Worksheets;
//Get the allready exists sheet
mWSheet1 = (Excel.Worksheet)mWorkSheets.get_Item(1);
//Excel.Range range = mWSheet1.UsedRange;
//int colCount = range.Columns.Count;
//int rowCount = range.Rows.Count;
int countRows = mWSheet1.UsedRange.Rows.Count;
int countColumns = mWSheet1.UsedRange.Columns.Count;
object[,] data = mWSheet1.Range[mWSheet1.Cells[1, 1], mWSheet1.Cells[countRows, countColumns]].Cells.Value2;
for (int index = 1; index < 15; index++)
{
mWSheet1.Cells[countRows + index, 1] = countRows + index;
mWSheet1.Cells[countRows + index, 2] = "test" + index;
}
//Excel.Worksheet sheet = workbook.ActiveSheet;
//Excel.Range rng = (Excel.Range)sheet.get_Range(sheet.Cells[1, 1], sheet.Cells[3, 3]);
mWorkBook.SaveAs(path, Excel.XlFileFormat.xlOpenXMLWorkbookMacroEnabled,Missing.Value, Missing.Value, Missing.Value, Missing.Value, Excel.XlSaveAsAccessMode.xlExclusive,Missing.Value, Missing.Value, Missing.Value,Missing.Value, Missing.Value);
mWorkBook.Close(Missing.Value, Missing.Value, Missing.Value);
mWSheet1 = null;
mWorkBook = null;
oXL.Quit();
GC.WaitForPendingFinalizers();
GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
}
I tried it with get_range but i get an exception that this is not aviable.
It has something to do with the Microsoft.Office.Interop libary 14. Then i tried it with object[,] but the only thing i got to work is that after all used cells to insert test but not to select anything. So any help would be great.
Thanks for your Time and sorry for my english.
EDIT: At least the read process works now and i loop trough a selected range.
Here is the working code:
public void writeExcelFile()
{
String inputFile = #"C:\Users\AAN\Documents\Visual Studio 2015\Projects\WorkWithExcel\WorkWithExcel\bin\Debug\PROJEKTSTATUS_GESAMT_neues_Layout.xlsm";
Excel.Application oXL = new Excel.Application();
#if DEBUG
oXL.Visible = true;
oXL.DisplayAlerts = true;
#else
oXL.Visible = false;
oXL.DisplayAlerts = false;
#endif
//Open the Excel File
Excel.Workbook oWB = oXL.Workbooks.Open(inputFile);
String SheetName = "Gesamt";
Excel._Worksheet oSheet = oWB.Sheets[SheetName];
String start_range = "B4";
String end_range = "R81";
Object[,] values = oSheet.get_Range(start_range, end_range).Value2;
int t = values.GetLength(0);
for (int i = 1; i <= values.GetLength(0); i++)
{
String val = values[i, 1].ToString();
}
oXL.Quit();
}
After many tries i finnaly got a working solution where i can select any cells i want. Maby there are better ways but for me it works as expected.
the code:
public void writeExcelFile()

This is not my own code its from a blog: the blog where i got it just edited so it works for me.
I want to make changes to an existing file named "Original" in the directory "C:\Users\Twiga\Documents\VisualStudio2010\Projects\MarkSheetSystem\Original.xls".
Currently, I am only able to save the data that I have exported from my datagridview1 to a new file but that is not my intention.
Below is the code:
private void btnexcel_Click(object sender, EventArgs e)
{
Microsoft.Office.Interop.Excel._Application excel = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel._Workbook workbook = excel.Workbooks.Add(Type.Missing);
Microsoft.Office.Interop.Excel._Worksheet worksheet = null;
try
{
worksheet = workbook.ActiveSheet;
worksheet.Name = "Marksheet 1";
worksheet.Cells[12, 1] = dataGridView1.Rows[0].Cells[0].Value.ToString();
int cellRowIndex = 10;
int cellColumnIndex = 1;
//Loop through each row and read value from each column.
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
for (int j = 1; j < dataGridView1.Columns.Count - 1; j++)
{
// Excel index starts from 1,1. As first Row would have the Column headers, adding a condition check.
if (cellRowIndex == 0)
{
worksheet.Cells[cellRowIndex, cellColumnIndex] = dataGridView1.Columns[j].HeaderText;
}
else
{
worksheet.Cells[cellRowIndex, cellColumnIndex] = dataGridView1.Rows[i].Cells[j].Value.ToString();
}
cellColumnIndex++;
}
cellColumnIndex = 1;
cellRowIndex++;
}
//Getting the location and file name of the excel to save from user.
SaveFileDialog saveDialog = new SaveFileDialog();
saveDialog.Filter = "Excel files (*.xlsx)|*.xlsx|All files (*.*)|*.*";
saveDialog.FilterIndex = 2;
if (saveDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
workbook.SaveAs(saveDialog.FileName);
MessageBox.Show("The marksheet has been saved successfully!");
}
}
catch (System.Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
excel.Quit();

Pertinent to your task, it would be better to export data to Excel Workbook from the DataGridView underlying DataTable (e.g. DataTable _dt = (DataTable)(datagridview1.DataSource)) as shown in the following C# sample code snippet:
/// <summary>
/// export DataTable to Excel (C#)
/// </summary>
internal static void Export2Excel(DataTable dataTable)
{
object misValue = System.Reflection.Missing.Value;
Microsoft.Office.Interop.Excel.Application _appExcel = null;
Microsoft.Office.Interop.Excel.Workbook _excelWorkbook = null;
Microsoft.Office.Interop.Excel.Worksheet _excelWorksheet = null;
try
{
// excel app object
_appExcel = new Microsoft.Office.Interop.Excel.Application();
// excel workbook object added
// can be replaced with _appExcel.Workbooks.Open(...)
_excelWorkbook = _appExcel.Workbooks.Add(misValue);
_excelWorksheet = _appExcel.ActiveWorkbook.ActiveSheet as Microsoft.Office.Interop.Excel.Worksheet;
// column names row (range obj)
Microsoft.Office.Interop.Excel.Range _columnsNameRange;
_columnsNameRange = _excelWorksheet.get_Range("A1", misValue).get_Resize(1, dataTable.Columns.Count);
// column names array to be assigned to _columnNameRange
string[] _arrColumnNames = new string[dataTable.Columns.Count];
for (int i = 0; i < dataTable.Columns.Count; i++)
{
// array of column names
_arrColumnNames[i] = dataTable.Columns[i].ColumnName;
}
// assign array to column headers range, make 'em bold
_columnsNameRange.set_Value(misValue, _arrColumnNames);
_columnsNameRange.Font.Bold = true;
// populate data content row by row
for (int Idx = 0; Idx < dataTable.Rows.Count; Idx++)
{
_excelWorksheet.Range["A2"].Offset[Idx].Resize[1, dataTable.Columns.Count].Value =
dataTable.Rows[Idx].ItemArray;
}
// Autofit all Columns in the range
_columnsNameRange.Columns.EntireColumn.AutoFit();
}
catch { throw; }
}
This will significantly improve the performance by exporting the entire data row at once instead of doing it cell-by-cell.
The only changes you have to make is to replace the line that adds new Workbook:
_excelWorkbook = _appExcel.Workbooks.Add(misValue);
with another one, opening the existing Excel File (e.g. "ExcelFilePath"), like:
_excelWorkbook = _appExcel.Workbooks.Open("ExcelFilePath",
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing);
Hope this may help.
I am trying to export 2 datagridviews to excel but it is missing the last line of data for both of the sets of data grid views, I have checked the code and I cant see what I have done wrong? Also it is creating a temporary file when exporting and then locking the file and not exiting gracefully and only a reboot allows you to delete the file? Any help would be great code is below. For example if i save as test.xlsx I get 2 files ~$test.xlsx and test.xlsx and both both files are locked.
private void exprtbtn_Click(object sender, EventArgs e)
{
Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing);
try
{
// creating new Excelsheet in workbook
Microsoft.Office.Interop.Excel._Worksheet worksheet1 = null;
Microsoft.Office.Interop.Excel._Worksheet worksheet2 = null;

// store its reference to worksheet
worksheet1 = workbook.Sheets["Sheet1"];
worksheet1 = workbook.ActiveSheet;

worksheet2 = workbook.ActiveSheet;
// changing the name of active sheet
worksheet2.Name = "Itemised Extn";
// storing header part in Excel
for (int i = 1; i < fullresult.Columns.Count + 1; i++)
{
worksheet2.Cells[1, i] = fullresult.Columns[i - 1].HeaderText;
}
// storing Each row and column value to excel sheet
for (int i = 0; i < fullresult.Rows.Count - 1; i++)
{
for (int j = 0; j < fullresult.Columns.Count; j++)
{
if (fullresult.Rows[i].Cells[j].Value == null)
{
fullresult.Rows[i].Cells[j].Value = "NA";
}
worksheet2.Cells[i + 2, j + 1] = fullresult.Rows[i].Cells[j].Value.ToString();
}
}
// save the application
string fileName = String.Empty;
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "Excel files |*.xls|All files (*.*)|*.*";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{

workbook.SaveAs(fileName, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
}
else
return;

//Catch all errors.
catch (System.Exception)

finally
{
workbook = null;

}
}
You probably might want to double-check your outer for loop again, e.g. for (int i = 0; i < fullresult.Rows.Count - 1; i++), shouldn't it be using less than and equal perhaps?
Since you are using Excel com interop, you will need to call this method to be able to release the resource after you are done with it, Marshal.ReleaseComObject.
A good practice is to use try{...}catch{...}finally{...}, and release com object in the finally block.
I have this code that export an excel file using c# from 1 listview. My problem now is if I have 2 listviews that will be generated in 1 excel file, my plan is listview1 is for sheet1 and listview2 is for sheet2.
this is my code generates listview1 to excel into sheet1:
string[] st = new string[listView1.Columns.Count];
DirectoryInfo di = new DirectoryInfo(Environment.ExpandEnvironmentVariables("%USERPROFILE%") + #"\Desktop\");
if (di.Exists == false)
di.Create();
fileName f = new fileName();
if (f.ShowDialog() == DialogResult.OK)
{
StreamWriter sw = new StreamWriter(Environment.ExpandEnvironmentVariables("%USERPROFILE%") + #"\Desktop\" + f.Filenam + ".xls", false);
sw.AutoFlush = true;
string header = "";
for (int col = 0; col < listView1.Columns.Count; col++)
{
header += listView1.Columns[col].Text.ToString() + "\t";
}
sw.Write(header);
int rowIndex = 1;
int row = 0;
string st1 = "";
for (row = 0; row < listView1.Items.Count; row++)
{
if (rowIndex <= listView1.Items.Count)
rowIndex++;
st1 = "\n";
for (int col = 0; col < listView1.Columns.Count; col++)
{
st1 = st1 + listView1.Items[row].SubItems[col].Text.ToString() + "\t";
}
sw.Write(st1);
}
sw.Close();
FileInfo fil = new FileInfo(Environment.ExpandEnvironmentVariables("%USERPROFILE%") + #"\Desktop\" + f.Filenam + ".xls");
if (fil.Exists == true)
MessageBox.Show("Process Completed", "Export to Excel", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
I have used EPPlus, its free, give performance benefits, and provides many Excel functions. Other option you can look for is Microsoft InterOp for Excel export, but it has performance problems.
As Irfan already mentioned, you could do that with Microsoft.Office.Interop
Excel.Application xlsApp = new Excel.Application();
Excel.Workbook workbook;
workbook = xlsApp.Workbooks.Open(configuration.XLSExportedFile, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
foreach (Excel.Worksheet sheet in workbook.Sheets)
{
workbook.Activate();
sheet.Activate();
}
That would help you to step through all your sheets in your Excel file.
Now in case you want to expand it with multiple sheets, you can read C# how to add Excel Worksheet programmatically Office XP / 2003 in order to find how to add additional sheets.
What you could do now, is put your text into a variable for example HTML or any kind of information from your listbox.
string html = Clipboard.GetText(TextDataFormat.Html);
Now you can play around with the Clipboard(alternative solution, but to avoid).
Clipboard.SetText(html);
It actually enters information into your Clipboard, what you could do is pass all your listbox values into the Clipboard.
And now the final step would be to paste it at the position that you want.
sheet.Range(cellmapp).PasteSpecial();
Where cellmap is supposed to be for example A1. In case your text that you have in your listbox is too long you can adapt your rows/columns.
//Auto fits all columns and rows
//https://stackoverflow.com/questions/14748322/c-sharp-autofit-method-for-excel-sheet
sheet.Columns.AutoFit();
sheet.Rows.AutoFit();
Don't forget, if you work with COM processes, close every object and file.
workbook.SaveAs(configuration.XLSExportedFile);
workbook.Close();
xlsApp.Quit();
xlsApp.Dispose();
I don't say that would be the best solution to do, but you could look up for OpenXML also.
I've used ClosedXML before, the syntax is really clean and simple and you can get this sort of task done in just a few lines
