如何将我的导出格式化为microsoft.office.interop.excel中的excel工作簿？
我有这个导出功能，允许我在一个excel中将2个网格视图导出为2个独立的工作表。
但我的问题是：
当我点击导出按钮以提示用户打开，另存为，取消下载而不是将其保存到特定位置（目前我在我的代码中正在执行的操作）时，如何才能像平常下载一样使用常见的弹出窗口？
我如何设置代码以启用所有单元格的wraptext = true，并自动格式化列高和宽以固定所有文本，以便在列宽不变时不显示######作为示例excel打开时太小。
protected void EXPORT_BUTTON_Click（object sender，EventArgs e）{Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application（）; //在Excel应用程序中创建新的WorkBook Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add（Type.Missing）;
String DT1 = "Data table 1";
String DT2 = "Data table 2";
ExportToExcel(app, workbook, Gridview1, DT1, 1);
ExportToExcel(app, workbook, Gridview2, DT2, 2);
}
public void ExportToExcel(Microsoft.Office.Interop.Excel._Application app, Microsoft.Office.Interop.Excel._Workbook workbook, GridView gridview, string SheetName, int sheetid)
{
// see the excel sheet behind the program
app.Visible = true;
// get the reference of first sheet. By default its name is Sheet1.
// store its reference to worksheet
worksheet = (Excel.Worksheet)workbook,Worksheets.Add();
// changing the name of active sheet
worksheet.Name = SheetName;
// storing header part in Excel
for (int i = 1; i < gridview.Columns.Count + 1; i++)
{
worksheet.Cells[1, i] = gridview.Columns[i - 1].HeaderText;
}
// storing Each row and column value to excel sheet
for (int i = 0; i < gridview.Rows.Count - 1; i++)
{
for (int j = 0; j < gridview.Columns.Count; j++)
{
worksheet.Cells[i + 2, j + 1] = gridview.Rows[i].Cells[j].Text.ToString();
}
}
//save the application
workbook.SaveAs(@"C:UserstestDesktopTest" + datetime.ToString("dd-MM-yyyy_hh-mm-ss") + ".xls", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
}
}
修改Excel文件的路径以保存到虚拟路径，如下所示
workbook.SaveAs(@"C:UserstestDesktopTest" + datetime.ToString("dd-MM-yyyy_hh-mm-ss") + ".xls", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
改变这个
workbook.SaveAs(@"~/ExcelFiles/Filename.xlsx" + datetime.ToString("dd-MM-yyyy_hh-mm-ss") + ".xls", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
尝试以下代码以显示另存为对话框
String FileName = "FileName.xlsx";
String FilePath = "~/ExcelFiles/FileName.xlsx";
System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;
response.ClearContent();
response.Clear();
response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
response.AddHeader("Content-Disposition", "attachment; filename=" + FileName + ";");
response.TransmitFile(FilePath);
response.Flush();
response.End();
尝试这个：
Excel.Worksheet worksheet =(Excel.Worksheet)workbook.Worksheets["Sheet" + sheetid];
如Laxmikant指定的那样修改您的方法“ExportToExcel”的代码，如下所示。
public void ExportToExcel(Microsoft.Office.Interop.Excel._Application app, Microsoft.Office.Interop.Excel._Workbook workbook, GridView gridview, string SheetName, int sheetid)
{
// see the excel sheet behind the program
app.Visible = true;
worksheet = (Excel.Worksheet)workbook.Worksheets.Add();
// changing the name of active sheet
worksheet.Name = SheetName;
// storing header part in Excel
for (int i = 1; i < gridview.Columns.Count + 1; i++)
{
worksheet.Cells[1, i] = gridview.Columns[i - 1].HeaderText;
}
// storing Each row and column value to excel sheet
for (int i = 0; i < gridview.Rows.Count - 1; i++)
{
for (int j = 0; j < gridview.Columns.Count; j++)
{
worksheet.Cells[i + 2, j + 1] = gridview.Rows[i].Cells[j].Text.ToString();
}
}
我删除了这两行代码，现在不需要参数“Sheetid”
Excel.Worksheet worksheet =(Excel.Worksheet)workbook.Worksheets["Sheet" + sheetid];
worksheet = workbook.ActiveSheet;
希望这能解决你的问题
