C# 将用户控件gridview导出到excel

在我的aspx页面上，我有一个

Usercontrol

，其中包含一个

Gridview

，它的数据根据从aspx页面传递到Usercontrol的参数动态加载，我称之为

QuotesReport1

当导出运行时，它只将布局导出到

电子表格中

，而不导出gridview的任何数据，例如：

---

在UserControl内部运行SQL查询，该查询返回一个DataTable，然后将其绑定到UserControl内部的Gridview，如下所示：

SQLData da = new SQLData();
GridView1.DataSource = da.SGetDataTable(query);
GridView1.DataBind();

我所拥有的最简单的方法

public class ExcelUtility
{
    public static void ToExcel(object dataSource)
    {
        GridView grid = new GridView { DataSource = dataSource };
        grid.DataBind();

        StringBuilder sb = new StringBuilder();
        foreach (TableCell cell in grid.HeaderRow.Cells)
            sb.Append(string.Format("\"{0}\",", cell.Text));
        sb.Remove(sb.Length - 1, 1);
        sb.AppendLine();

        foreach (GridViewRow row in grid.Rows)
        {
            foreach (TableCell cell in row.Cells)
                sb.Append(string.Format("\"{0}\",", cell.Text.Trim().Replace(" ", string.Empty)));
            sb.Remove(sb.Length - 1, 1);
            sb.AppendLine();
        }
        ExportToExcel(sb.ToString());
    }

    private static void ExportToExcel(string data)
    {
        HttpContext.Current.Response.Clear();
        HttpContext.Current.Response.AddHeader("content-disposition", "attachment;filename=Report.csv");
        HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8");
        HttpContext.Current.Response.ContentType = "text/csv";
        HttpContext.Current.Response.Write(data);
        HttpContext.Current.Response.End();
    }
}

使用：

   string result = ExcelUtility.ToExcel(_db.FindAll());
   ExcelUtility.ExportToExcel(result);

在将数据写入excel工作表之前，请绑定网格。绑定网格视图的代码在哪里？请将该代码粘贴到原始问题中。。注释部分的格式很难阅读…Thanx@DJKRAZE，我已经相应地更新了。只是一个简单的问题，网格是否实际显示了任何数据。。？您是否已在Page_Load事件中遍历代码，并在UserControl所在的代码中放置断点。。？

public class ExcelUtility
{
    public static void ToExcel(object dataSource)
    {
        GridView grid = new GridView { DataSource = dataSource };
        grid.DataBind();

        StringBuilder sb = new StringBuilder();
        foreach (TableCell cell in grid.HeaderRow.Cells)
            sb.Append(string.Format("\"{0}\",", cell.Text));
        sb.Remove(sb.Length - 1, 1);
        sb.AppendLine();

        foreach (GridViewRow row in grid.Rows)
        {
            foreach (TableCell cell in row.Cells)
                sb.Append(string.Format("\"{0}\",", cell.Text.Trim().Replace(" ", string.Empty)));
            sb.Remove(sb.Length - 1, 1);
            sb.AppendLine();
        }
        ExportToExcel(sb.ToString());
    }

    private static void ExportToExcel(string data)
    {
        HttpContext.Current.Response.Clear();
        HttpContext.Current.Response.AddHeader("content-disposition", "attachment;filename=Report.csv");
        HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8");
        HttpContext.Current.Response.ContentType = "text/csv";
        HttpContext.Current.Response.Write(data);
        HttpContext.Current.Response.End();
    }
}

   string result = ExcelUtility.ToExcel(_db.FindAll());
   ExcelUtility.ExportToExcel(result);
