gridview导出excel时设置excel为文本格式

[tctc7563]

我把GridView中的数据用一个导出excel的类导出来，但发现里面有些编号原先是以0开头的，比如01001，但导出来到Excel中发现都成1001了，0没了。我想把excel的格式设成文本格式，但不知怎么弄。
public class GridViewExportUtil
{

public GridViewExportUtil()
{
//
// TODO: 在此处添加构造函数逻辑
//
}
public static void Export(string fileName, GridView gv)
{
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader(
"content-disposition", string.Format("attachment; filename={0}", fileName));
HttpContext.Current.Response.ContentType = "application/ms-excel";

using (StringWriter sw = new StringWriter())
{
using (HtmlTextWriter htw = new HtmlTextWriter(sw))
{
// Create a form to contain the grid
Table table = new Table();

// add the header row to the table
if (gv.HeaderRow != null)
{
GridViewExportUtil.PrepareControlForExport(gv.HeaderRow);
table.Rows.Add(gv.HeaderRow);
}

// add each of the data rows to the table
foreach (GridViewRow row in gv.Rows)
{
GridViewExportUtil.PrepareControlForExport(row);
table.Rows.Add(row);
}

// add the footer row to the table
if (gv.FooterRow != null)
{
GridViewExportUtil.PrepareControlForExport(gv.FooterRow);
table.Rows.Add(gv.FooterRow);
}

// render the table into the htmlwriter
table.RenderControl(htw);

// render the htmlwriter into the response
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.Response.End();
}
}
}

/// <summary>
/// Replace any of the contained controls with literals
/// </summary>
/// <param name="control"></param>
private static void PrepareControlForExport(Control control)
{
for (int i = 0; i < control.Controls.Count; i++)
{
Control current = control.Controls[i];
if (current is LinkButton)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as LinkButton).Text));
}
else if (current is ImageButton)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as ImageButton).AlternateText));
}
else if (current is HyperLink)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as HyperLink).Text));
}
else if (current is DropDownList)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as DropDownList).SelectedItem.Text));
}
else if (current is CheckBox)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as CheckBox).Checked ? "True" : "False"));
}

if (current.HasControls())
{
GridViewExportUtil.PrepareControlForExport(current);
}
}
}
}

使用XML模版导
打开Excel然后设置好格式另存别计算XML格式保存。
你看我的空间里有一个类可以用的，我公司里一直用的就是这个了

设计excel模板。操作excel导出数据到单元格
设置单元格格式
或使用'
mySheet.Cells(1,9).NumberFormatLocal = "@"
Excel.Range r = mySheet.get_Range(mySheet.Cells[1, 1], mySheet.Cells[1，3]);
r.NumberFormat = "@";
或使用Stream

要是操作量非常大呢？
有很多地方都有类似的导出，难道要一个个全部改？
