is there a way to export the whole data in one table from sql server 2008 directly using asp.net and vb.net without using datagridview to EXCEL FILE?

推荐答案

基本上，你只需要遍历所有的列和你的数据表中的行，以便将它们输出到响应。 <一href=\"http://www.$c$cdigest.com/Articles/ASPNET/130_Export_to_Excel_in_ASPNet_20_%E2%80%93Gridview_to_Excel_DataTable_to_Excel.aspx\">This链接告诉您如何。

Basically, you just need to loop over the columns and rows of your DataTable in order to output them to the response. This link shows you how.

在C＃中：

        DataTable dt = GetData();
        string attachment = "attachment; filename=Employee.xls";
        Response.ClearContent();
        Response.AddHeader("content-disposition", attachment);
        Response.ContentType = "application/vnd.ms-excel";
        string tab = "";
        foreach (DataColumn dc in dt.Columns)
        {
            Response.Write(tab + dc.ColumnName);
            tab = "\t";
        }
        Response.Write("\n");

        int i;
        foreach (DataRow dr in dt.Rows)
        {
            tab = "";
            for (i = 0; i < dt.Columns.Count; i++)
            {
                Response.Write(tab + dr[i].ToString());
                tab = "\t";
            }
            Response.Write("\n");
        }
        Response.End();

在VB.NET

    Dim dt As DataTable = GetData()
    Dim attachment As String = "attachment; filename=Employee.xls"
    Response.ClearContent()
    Response.AddHeader("content-disposition", attachment)
    Response.ContentType = "application/vnd.ms-excel"
    Dim tab As String = ""
    For Each dc As DataColumn In dt.Columns
        Response.Write(tab + dc.ColumnName)
        tab = vbTab
    Next
    Response.Write(vbLf)

    Dim i As Integer
    For Each dr As DataRow In dt.Rows
        tab = ""
        For i = 0 To dt.Columns.Count - 1
            Response.Write(tab & dr(i).ToString())
            tab = vbTab
        Next
        Response.Write(vbLf)
    Next
    Response.End()
