how to upload pdf file in asp.net C#

If your main requirement is to display and view JPEG and PDF files after uploading them, you can try using HTML5 Document Viewer control and services from LEADTOOLS.

The following JavaScript code loads a PDF document file at the client side:

var _this = this;
window.onload = function () {
var createOptions = new lt.Document.Viewer.DocumentViewerCreateOptions();
createOptions.viewCreateOptions.useElements = true;
createOptions.thumbnailsCreateOptions.useElements = true;
createOptions.thumbnailsContainer = document.getElementById("thumbnails");
createOptions.viewContainer = document.getElementById("documentViewer");
_this.documentViewer = lt.Document.Viewer.DocumentViewerFactory.createDocumentViewer(createOptions);
_this.documentViewer.commands.run(lt.Document.Viewer.DocumentViewerCommands.interactivePanZoom);
_this.documentViewer.view.preferredItemType = lt.Document.Viewer.DocumentViewerItemType.svg;
_this.documentViewer.thumbnails.imageViewer.viewHorizontalAlignment = lt.Controls.ControlAlignment.center;
lt.Document.DocumentFactory.serviceHost = "http://TheAddressOfTheService";
lt.Document.DocumentFactory.servicePath = "";
lt.Document.DocumentFactory.serviceApiPath = "api";
var url = "https://YourWebAddress/files/file.pdf";
lt.Document.DocumentFactory.loadFromUri(url, null)
.done(function (document) {
_this.documentViewer.setDocument(document);
})
};
