Sql server 使用mvc通过浏览器从数据库导出excel文件
我想使用mvc“通过浏览器”将sql表格数据导出到客户端pc上的excel文件。我使用的是:Sql server 使用mvc通过浏览器从数据库导出excel文件,sql-server,asp.net-mvc,export-to-excel,Sql Server,Asp.net Mvc,Export To Excel,我想使用mvc“通过浏览器”将sql表格数据导出到客户端pc上的excel文件。我使用的是: public class ManagementController : Controller { public void ExportitemToExcel() { try { dt = SqlHelper.LoadTable("SM_GetAllItems", sql);
public class ManagementController : Controller
{
public void ExportitemToExcel()
{
try
{
dt = SqlHelper.LoadTable("SM_GetAllItems", sql);
if (dt != null && dt.Rows.Count > 0)
{
ExportToExcel(dt);
}
}
catch
{ throw; }
}
以下是导出到excel的方法:
private void ExportToExcel(DataTable dt)
{
Microsoft.Office.Interop.Excel.Application excel;
Microsoft.Office.Interop.Excel.Workbook worKbooK;
Microsoft.Office.Interop.Excel.Worksheet worKsheeT;
excel = new Microsoft.Office.Interop.Excel.Application();
excel.Visible = false;
excel.DisplayAlerts = false;
worKbooK = excel.Workbooks.Add(Type.Missing);
worKsheeT = (Microsoft.Office.Interop.Excel.Worksheet)worKbooK.ActiveSheet;
worKsheeT.Name = "Inventory";
//Create an Excel workbook instance and open it from the predefined location
// Excel.Workbook excelWorkBook = excel.Workbooks.Open(@"E:\Org.xlsx");
// Excel.Worksheet excelWorkSheet = excelWorkBook.Sheets.Add();
//excelWorkSheet.Name = dt.TableName;
for (int i = 1; i < dt.Columns.Count + 1; i++)
{
worKsheeT.Cells[1, i] = dt.Columns[i - 1].ColumnName;
}
for (int j = 0; j < dt.Rows.Count; j++)
{
for (int k = 0; k < dt.Columns.Count; k++)
{
worKsheeT.Cells[j + 2, k + 1] = dt.Rows[j].ItemArray[k].ToString();
}
}
string fastExportFilePath = "C:/" + "Inventory" + ".xlsx";
if (System.IO.File.Exists(fastExportFilePath))
{
System.IO.File.Delete(fastExportFilePath);
}
worKbooK.SaveAs(fastExportFilePath);
worKbooK.Close();
excel.Quit();
private void ExportToExcel(数据表dt)
{
Microsoft.Office.Interop.Excel.Application Excel;
Microsoft.Office.Interop.Excel.Workbook工作簿;
Microsoft.Office.Interop.Excel.Worksheet工作表;
excel=新的Microsoft.Office.Interop.excel.Application();
excel.Visible=false;
excel.DisplayAlerts=false;
工作簿=excel.Workbooks.Add(Type.Missing);
工作表=(Microsoft.Office.Interop.Excel.worKsheeT)worKbooK.ActiveSheet;
工作表.Name=“库存”;
//创建Excel工作簿实例并从预定义位置打开它
//Excel.工作簿Excel工作簿=Excel.Workbooks.Open(@“E:\Org.xlsx”);
//Excel.Worksheet excelWorkSheet=excelWorkBook.Sheets.Add();
//excelWorkSheet.Name=dt.TableName;
对于(int i=1;i
这将以静默方式创建文件,即不通过浏览器。您不能将excel直接保存到客户端的pc。您可以做的是将excel保存到服务器并与客户端共享以供下载 您可以修改ExportToExcel方法以返回生成的文件名,用于打开excel文件
private string ExportToExcel(DataTable dt)
{
//your code goes here
return fastExportFilePath
}
Javascript
$(document).ready(function () {
//Check if the hidden field has a value. (Excel was generated)
if ($('#hdnFileName').val() != '')
{
var url = "Full path to your file" + $('#hdnFileName').val();
window.location.assign(url)
}
});
