Html Open Directory Window to Upload a File

Introduction

In this article, yous'll understand how to upload files to the folder using the c# lawmaking. and step past footstep we'll create a Microsoft ASP.Net file (WebForm1.aspx) and its related code-behind file (WebForm1.aspx.cs) to file uploads.

Create an ASP.Cyberspace application

Allow'southward go to Visual Studio, follow these steps to create a new application to upload files using c#:

1. Open Visual Studio.
2. Select File carte, point to New then click on Projection.
3. In the New Project dialog box, click Visual C# Projects under Projection Types, and so click ASP.Cyberspace Web Awarding under Templates.

In the dialog Location box, type the URL to create the project. For this example, type
http://localhost/FileUpload, which creates the default project proper noun of FileUpload. Observe that the FileUpload.aspx file loads in the Designer view of Visual Studio .NET.

First, nosotros have to create a WinForm similar in the given code. Hither is the code for FileUpload.Designer.cs file.

          namespace FileUploads   {       partial form FileUpload       {           /// <summary>           /// Required designer variable.           /// </summary>           individual System.ComponentModel.IContainer components = null;
