我需要在ASPX页面内显示PDF文件（使用ASP.NET Control）在按钮上单击。

我当前已执行以下代码，该代码在Web浏览器中显示PDF文件。

string folderPath = 
    Server.MapPath(ConfigurationManager.AppSettings["serverFolderPath"].ToString());
foreach (string file in Directory.GetFiles(folderPath))
{
    WebClient user = new WebClient();
    Byte[] fileBuffer = user.DownloadData(file);
    if (fileBuffer != null)
    {
        Response.ContentType = "application/pdf";
        Response.AddHeader("content-length", fileBuffer.Length.ToString());
        sponse.BinaryWrite(fileBuffer);
    }
}

如果您的文件夹正确，请在以下代码下尝试它的工作

        string strDirectoryPath = @"C:UsersUserDesktopNameDesktop";
        WebClient User = new WebClient();
        foreach (string strFilePath in Directory.GetFiles(strDirectoryPath))
        {
            string strFileExtension = Path.GetExtension(strFilePath);
            if (strFileExtension == ".pdf")
            {
                Byte[] FileBuffer = User.DownloadData(strFilePath);
                this.Response.ContentType = "application/pdf";
                this.Response.AppendHeader("Content-Disposition;", "attachment;filename=" + FileBuffer);
                this.Response.WriteFile(strFilePath);
                this.Response.End();
            }
        }
