我正在使用下面的代碼使用Microsoft.Office.Interop.Excel導出excel。 [女士辦公室2003]。 我需要導出約150000行可以有最多300列。將數據表導出到Excel時出錯
但在Get_Range上出現錯誤。 excelSheet.get_Range(excelRange,類型:
public static void ExportToExcel(DataTable dt, string outputPath)
{
try
{
// Create the Excel Application object
ApplicationClass excelApp = new ApplicationClass();
// Create a new Excel Workbook
Workbook excelWorkbook = excelApp.Workbooks.Add(Type.Missing);
int sheetIndex = 0;
// Copy each DataTable
// Copy the DataTable to an object array
object[,] rawData = new object[dt.Rows.Count + 1, dt.Columns.Count];
// Copy the column names to the first row of the object array
for (int col = 0; col < dt.Columns.Count; col++)
{
rawData[0, col] = dt.Columns[col].ColumnName;
}
// Copy the values to the object array
for (int col = 0; col < dt.Columns.Count; col++)
{
for (int row = 0; row < dt.Rows.Count; row++)
{
rawData[row + 1, col] = dt.Rows[row].ItemArray[col];
}
}
// Calculate the final column letter
string finalColLetter = string.Empty;
string colCharset = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
int colCharsetLen = colCharset.Length;
if (dt.Columns.Count > colCharsetLen)
{
finalColLetter = colCharset.Substring(
(dt.Columns.Count - 1)/colCharsetLen - 1, 1);
}
finalColLetter += colCharset.Substring(
(dt.Columns.Count - 1) % colCharsetLen, 1);
// Create a new Sheet
Worksheet excelSheet = (Worksheet)excelWorkbook.Sheets.Add(
excelWorkbook.Sheets.get_Item(++sheetIndex),
Type.Missing, 1, XlSheetType.xlWorksheet);
excelSheet.Name = "data";
// Fast data export to Excel
string excelRange = string.Format("A1:{0}{1}",
finalColLetter, dt.Rows.Count + 1);
//excelSheet.get_Range(
excelSheet.get_Range(excelRange, Type.Missing).Value2 = rawData;
// Mark the first row as BOLD
((Range)excelSheet.Rows[1, Type.Missing]).Font.Bold = true;
// Save and Close the Workbook
excelWorkbook.SaveAs("C:\\Dashsrv\\data.Xls", XlFileFormat.xlWorkbookNormal, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, XlSaveAsAccessMode.xlExclusive,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
excelWorkbook.Close(true, Type.Missing, Type.Missing);
excelWorkbook = null;
// Release the Application object
excelApp.Quit();
excelApp = null;
// Collect the unreferenced objects
GC.Collect();
GC.WaitForPendingFinalizers();
MessageBox.Show("File created at");
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
}
獲得下面的代碼行
[{ 「0x800A03EC從HRESULT異常」}]錯誤[50000行和列40工作細]。缺少).Value2 = rawData;
IS Get_Range()
對行/列有一些限制嗎?
正如我所知的MS Office 2003列的限制是256,不知道行限制。
感謝
感謝您快速回復Knagis。 – Elliana 2013-05-09 10:53:07
請問您能否以其他方式快速導出excel?與上面相比? – Elliana 2013-05-09 10:59:06
嘗試使用OfficeOpenXML而不是Interop。 - http://excelpackage.codeplex.com/wikipage?title=Creating%20an%20Excel%20spreadsheet%20from%20scratch&referringTitle=Home – kgu87 2013-05-09 12:26:22
