打开一个新窗口codebehind ASP.net [英] Opening a new Window Codebehind ASP.net

问题描述

我有以下的code：

protected void Page_Load(object sender, EventArgs e)
{
        byte[] buffer = null;
        buffer = File.ReadAllBytes("C:\\myfile.pdf");
        HttpContext.Current.Response.ContentType = "application/pdf";
        HttpContext.Current.Response.OutputStream.Write(buffer, 0, buffer.Length);
        HttpContext.Current.Response.End();
}

我想开第二个窗口为当前页面，其中页面加载来自旁边的PFD文件。

I want to open a second window for the pfd file beside the current page, where the pageload comes from.

推荐答案

在为了做到这一点，你需要将PDF上传到一个路径在应用中它可以psented用户$ P $，然后注册一些JavaScript在新窗口中打开PDF：

In order to do this you'll need to upload the PDF to a path in the application where it can be presented to the user, then register some javascript to open the PDF in a new window:

protected void Page_Load(object sender, EventArgs e)
{
    byte[] buffer = null;
    buffer = File.ReadAllBytes("C:\\myfile.pdf");
    //save file to somewhere on server, for example in a folder called PDFs inside your application's root folder
    string newFilepath = Server.MapPath("~/PDFs/uploadedPDF.pdf");
    System.IO.FileStream savedPDF = File.Create(newFilepath);
    file.Write(buffer, 0, buffer.Length);
    file.Close();

    //register some javascript to open the new window
    Page.ClientScript.RegisterStartupScript(this.GetType(), "OpenPDFScript", "window.open(\"/PDFs/uploadedPDF.pdf\");", true);
}
