Question

我在ASP.Net 2.0中有一个gridview控件，我需要将这个gridview数据导出为CSV文件。

我已将此gridview与数据集绑定。将数据集绑定到gridview后，我在gridview数据中做了一些更改，如果我在数据集中得到0，那么我在gridview中显示0为“Started”，如果我得到了1在数据集中然后我在gridview中显示1为“未启动”。

所以，我不能直接使用数据集进行导出。我需要的是.. 我想要将我的gridview数据（不是数据集的数据）导出到CSV文件中的代码（在c＃中）。

Answer 1

尝试以下代码，我已多次使用它。它会将数据直接从gridview导出到代码中指定的csv文件。

protected void btnExportCSV_Click(object sender, EventArgs e)
{
    Response.Clear();
    Response.Buffer = true;
    Response.AddHeader("content-disposition",
     "attachment;filename=GridViewExport.csv");
    Response.Charset = "";
    Response.ContentType = "application/text";

    GridView1.AllowPaging = false;
    GridView1.DataBind();

    StringBuilder sb = new StringBuilder();
    for (int k = 0; k < GridView1.Columns.Count; k++)
    {
        //add separator
        sb.Append(GridView1.Columns[k].HeaderText + ',');
    }
    //append new line
    sb.Append("\r\n");
    for (int i = 0; i < GridView1.Rows.Count; i++)
    {
        for (int k = 0; k < GridView1.Columns.Count; k++)
        {
            //add separator
            sb.Append(GridView1.Rows[i].Cells[k].Text + ',');
        }
        //append new line
        sb.Append("\r\n");
    }
    Response.Output.Write(sb.ToString());
    Response.Flush();
    Response.End();
}

首先感谢Devjosh的好答案，我修改了它以使用具有AutoGenerateColumns = true和AllowSorting = true的网格视图。另外，我从数据中删除了任何返回的逗号，以确保csv文件没有损坏。

private void ExportReport()
{
    // set the resulting file attachment name to the name of the report...
    string fileName = "test";

    Response.Clear();
    Response.Buffer = true;
    Response.AddHeader("content-disposition", "attachment;filename=" + fileName + ".csv");
    Response.Charset = "";
    Response.ContentType = "application/text";

    System.Text.StringBuilder sb = new System.Text.StringBuilder();

    // Get the header row text form the sortable columns
    LinkButton headerLink = new LinkButton();
    string headerText = string.Empty;

    for (int k = 0; k < gvReport.HeaderRow.Cells.Count; k++)
    {
        //add separator
        headerLink = gvReport.HeaderRow.Cells[k].Controls[0] as LinkButton;
        headerText = headerLink.Text;
        sb.Append(headerText + ",");
    }
    //append new line
    sb.Append("\r\n");
    for (int i = 0; i < gvReport.Rows.Count; i++)
    {
        for (int k = 0; k < gvReport.HeaderRow.Cells.Count; k++)
        {
            //add separator and strip "," values from returned content...

            sb.Append(gvReport.Rows[i].Cells[k].Text.Replace(",", "") + ",");
        }
        //append new line
        sb.Append("\r\n");
    }
    Response.Output.Write(sb.ToString());
    Response.Flush();
    Response.End();
}

private void ExportGridToCSV()
        {            
            Response.Clear();
            Response.Buffer = true;
            Response.AddHeader("content-disposition", "attachment;filename=Employee.csv");
            Response.Charset = "";
            Response.ContentType = "application/text";
            GridEmployee.AllowPaging = false;
            GridEmployee.DataBind();

            StringBuilder columnbind = new StringBuilder();
            for (int k = 0; k < GridEmployee.Columns.Count; k++)
            {

                columnbind.Append(GridEmployee.Columns[k].HeaderText + ',');
            }

            columnbind.Append("\r\n");
            for (int i = 0; i < GridEmployee.Rows.Count; i++)
            {
                for (int k = 0; k < GridEmployee.Columns.Count; k++)
                {

                    columnbind.Append(GridEmployee.Rows[i].Cells[k].Text + ',');
                }

                columnbind.Append("\r\n");
            }
            Response.Output.Write(columnbind.ToString());
            Response.Flush();
            Response.End();

        }

只需在按钮Click事件中调用此方法即可。有关更多代码，请单击链接 Export gridview data into CSV file
