c# - 强制使用标签下载pdf

Answer 1

尝试这个。

public void download_Click(Object sender, EventArgs e)
{
    Response.AddHeader("Content-Type", "application/octet-stream");
    Response.AddHeader("Content-Transfer-Encoding","Binary");
    Response.AddHeader("Content-disposition", "attachment; filename=\"sample.pdf\"");
    Response.WriteFile(HttpRuntime.AppDomainAppPath + @"path\to\file\sample.pdf");
    Response.End();
}

<asp:LinkButton ID="download" runat="server" OnClick="download_Click">Download</asp:LinkButton>
