C# get_Resize(910000, 3) exception while adding data to excel

i am getting following exception "System.Runtime.InteropServices.COMException: 'Exception from HRESULT: 0x800A03EC" while adding array data to excel. I am only getting this error when first paramter passed is greater than "90000" "get_Resize(900000, 3)". Does any one know how to store data with thousands of records to excel file.Below is my code.
Microsoft.Office.Interop.Excel.Application excel;

Microsoft.Office.Interop.Excel.Worksheet worksheet;
Microsoft.Office.Interop.Excel.Range celLrangE;
excel = new Microsoft.Office.Interop.Excel.Application();

worKbooK = excel.Workbooks.Add(Type.Missing);
worksheet = (Microsoft.Office.Interop.Excel.Worksheet)worKbooK.ActiveSheet;
worksheet.Name = "StudentRepoertCard";

Merge Individual excel sheets data to Single Excel with multiple sheet

I am facing an issue regarding excel writing .Below is the problem -
I have a requirement for which I have multiple excel sheets and for each excel file there could be multiple sheets .So, I need to write in a single excel with multiple individual sheets
ex- Lets say I have 3 excel file File1.xlsx with Sheet1, File2.xlsx with Sheet2 and File 3 with multiple sheet Sheet3 and Sheet4.In each sheet the data is similar like 3 Columns (Name,EmployeeID,MobNo) So, the output would be Individual file Result.xlsx with multiple sheets Sheet1,Sheet2,Sheet3 & Sheet4.
Please share the code without any third party tools like Spire.xl.I need to do this programatically.Below is the code -
string inputPathFirstExcel =
#"C:\MyData\ExcelWritingApp\File1.xlsx";
string inputPathSecondExcel = #"C:\\ExcelWritingApp\File2.xlsx";
string[] ColumnData = { };
Excel.Application xlApp = null;
Excel.Workbook xlWorkBook = null;
Excel.Worksheet xlWorkSheet = null;
Excel.Range xlrange = null;
xlApp = new Excel.Application();
xlApp.Visible = false;
xlWorkBook = xlApp.Workbooks.Open(inputPathFirstExcel);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Sheets[1];
xlrange = xlWorkSheet.UsedRange;
object missing = Type.Missing;
Excel.Application oXL = new Excel.Application();
oXL.Visible = false;
Excel.Workbook oWB = oXL.Workbooks.Add(missing);
Excel.Worksheet oSheet = oWB.ActiveSheet as Excel.Worksheet;
oSheet.Name = "Sheet1";
Microsoft.Office.Interop.Excel.Range xlRange = xlWorkSheet.UsedRange;
DataTable dt = new DataTable();
dt.Columns.Add("Name");
dt.Columns.Add("Employee");
dt.Columns.Add("MobNo");
int rowCount = xlRange.Rows.Count;
int colCount = xlRange.Columns.Count;
for (int i = 1; i <= colCount; i++)
{
oSheet.Cells[1, i] = dt.Columns[i - 1].ToString().ToUpper() + "\t";
}
for (int i = 0; i < rowCount; i++)
{
for (int j = 1; j <= colCount; j++)
{
oSheet.Cells[i + 2, j] = Convert.ToString((xlRange.Cells[i + 2, j] as Excel.Range).Value2);
}
}
string fileName = #"C:\Result.xlsx";
oWB.SaveAs(fileName, Excel.XlFileFormat.xlOpenXMLWorkbook,
missing, missing, missing, missing,
Excel.XlSaveAsAccessMode.xlNoChange,

how to create excel sheet which contain maximum 30 sheets in c#

I want to create excel from datatable, And want to create maximum 25 sheets(each day for current month excluding weekend, Saturday,Sunday and bank holiday) , how can we do this by taking string of array for total days in month and datatable.
Public static void CreateExcel_TabNameUnique( DataTable dt1,string ExcelFilePath, string Tab_Name1)
{
try
{
runDate = DateTime.Today;
currMonth = DateTime.Today;
object missing = Type.Missing;
Excel.Application oXL = new Excel.Application();
oXL.Visible = false;
Excel.Workbook oWB = oXL.Workbooks.Add(missing);
Excel.Worksheet oSheet = oWB.ActiveSheet as Excel.Worksheet;
oSheet.Name = Tab_Name1;
// column headings
for (int i = 0; i < dt1.Columns.Count; i++)
{
oSheet.Cells[1, (i + 1)] = dt1.Columns[i].ColumnName;
}
// rows
for (int i = 0; i < dt1.Rows.Count; i++)
{
for (int j = 0; j < dt1.Columns.Count; j++)
{
oSheet.Cells[(i + 2), (j + 1)] = dt1.Rows[i][j];
}
}
if (ExcelFilePath != null && ExcelFilePath != "")
{
try
{
oWB.SaveAs(ExcelFilePath, Excel.XlFileFormat.xlOpenXMLWorkbook,
missing, missing, missing, missing,
Excel.XlSaveAsAccessMode.xlNoChange,
missing, missing, missing, missing, missing);
oWB.Close(missing, missing, missing);
oXL.UserControl = true;
oXL.Quit();
}
catch (Exception ex)
{
}
}
}
catch (Exception ex)
{
}
}

Sorry for not being able to verify this at the moment (problems with Excel Interop...), but from your comment I take it your problem is just in adding a second worksheet. You should be able to do this with:
Excel.Worksheet secondWorkSheet = oWB.Worksheets.Add();
Then proceed to manipulate worksheet as you are doing in the code you posted.

excel import using c#

i am working on excel import to grid view using DataTable in c#, but my problem is its working fine on my local system but its redirecting to login page on my online server and i have tried both Microsoft.Office.Interop.Excel & OLEdb connection. but the problem is same. please tell me what is the problem with these or any one have any other function to import Excel data in GridView.

It is better not using MS Office interop in server cases which will bring a lot of performance and memory issues in the future. Recommend using some 3rd party library, for example: https://www.nuget.org/packages/Spread.Services/ to get what you wanted.

Import excel sheet data to datagrid without using oledb

In my Windows based application(C#)
i want to import excel sheet to show its data in DatatGridView
i dont want to use oledb
any Help

You'll obviously need to add the reference to your project, and then it's plain simple :)

Excel.Worksheet worksheet = (Excel.Worksheet)sheets.get_Item(1);
Excel.Range range = worksheet.UsedRange;
System.Array myvalues = (System.Array)range.Cells.Value2;
int vertical = myvalues.GetLength(0);

}

I'm late to the party, but I have something worthwhile to add! I tried Juan's code and it didn't compile out-of-the-box. I modified it a little bit after researching the internet for a few more hours and got it to do exactly what the original poster asked (as I needed to do the same thing). I had to piece code together from other sources, and unfortunately, I did not keep track of what bits and pieces I tried and changed so I can't comment much about it.
The following code works in Visual Studio 2008 with .NET 3.5. Also, the formatting is lost when the data is put into the array (for example, dates become doubles which require a conversion with DateTime.FromOADate() to change it back). The issue with that is you can't tell if a value is an actual double or a date from a coding viewpoint, but if you know ahead of time a column is going to be a date, then format it as you insert the data into the table.
