在网页中添加“导出到 Excel”按钮，以在 Web 应用程序中将 gridview 导出到 Excel

我为诊所构建了一个患者管理软件，我需要将患者列表从 ASP.net 网格视图导出到 Excel 文件

我的问题是：

有没有办法将gridview导出到excel 我正在使用 vb.net 和 Visual Web Developer 2010

我将高级搜索页面的数据源存储到会话中并重定向到结果页面 这是结果页面的代码

Partial Class Sresults
Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    GridView1.DataSource = Session("dsource")
    GridView1.DataBind()

End Sub

Protected Sub Backbtn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Backbtn.Click
    Session("dsource") = ""
    Response.Redirect("searchme.aspx")

End Sub

Protected Sub Page_PreRenderComplete(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRenderComplete
    Response.Write(GridView1.Rows.Count.ToString + " Records")
End Sub
End Class

尝试在按钮上单击以下代码

// Get DataTable that DataGrid is bound to.
var dataTable = (DataTable)dataGrid.DataSource;

// Create new ExcelFile.
var ef = new ExcelFile();
// Add new worksheet to the file.
var ws = ef.Worksheets.Add(dataTable.TableName);
// Insert the data from DataTable to the worksheet starting at cell "A1".
ws.InsertDataTable(dataTable, "A1", true);

// Stream file to browser.
Response.Clear();
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("Content-Disposition", "attachment; filename=Employee.xls");
ef.SaveXls(Response.OutputStream);
Response.End();
