推荐答案

我只是猜测你希望用户能够点击在链接上？

因此将其输出为链接而不是Response.Redirect：这是我用来将类似链接放入HTML表格的文本：

I''m just guessing that you want the user to be able to click on a link?
So output it as a link instead of Response.Redirect: This is the text I use to put similar links into an HTML table:

/// <summary>
/// Add a download file's information to a table row.
/// </summary>
/// <param name="dl"></param>
/// <returns></returns>
private static HtmlTableRow AddDownloadFile(Downloadable dl)
    {
    HtmlTableRow row = new HtmlTableRow();
    // File name
    HtmlTableCell cell = new HtmlTableCell();
    cell.InnerHtml = "<a href=\"FileTransferDownload.aspx?file=" + dl.Id + "\" target=\"_blank\">" + dl.FileName + "</a>";
    row.Cells.Add(cell);
    // Version
    cell = new HtmlTableCell();
    cell.InnerText = dl.Version.ToString();
    row.Cells.Add(cell);
    // Upload date
    cell = new HtmlTableCell();
    cell.InnerText = dl.UploadedOn.ToString();
    row.Cells.Add(cell);
    return row;
    }

您可能需要调整它以适合您正在做的事情，但它显示了我使用的链接格式。

You may need to tweak it to fit exactly what you are doing, but it shows the link format I use.
