Access sharepoint online document list through asp net

Introduction

Accessing a SharePoint Online document list through ASP.NET can be a powerful way to integrate your web application with SharePoint. In this article, we will explore how to achieve this using the ASP.NET programming language.

Prerequisites

we begin, make sure you have the following:

  • An active SharePoint Online account
  • Studio installed on your machine
  • Basic knowledge of ASP.NET programming

Step 1: Setting up the ASP.NET Project

First, let's a new ASP.NET project in Visual Studio. Open Visual Studio and select “Create a new project”. Choose the ASP.NET Web Application and a name for your project. Click “OK” to create the project.

Step 2: Adding SharePoint Online Client Libraries

In to access SharePoint Online, we need to add the necessary client libraries to our project. Right-click on the project in the Solution Explorer and select “Manage NuGet ”. Search for “Microsoft.SharePointOnline.CSOM” and install the package.

Step 3: Authenticating with SharePoint Online

Before we can access the document list, we need to authenticate with SharePoint Online. Add the following code at the beginning of your ASP.NET code:


using Microsoft.SharePoint.Client;

string siteUrl = "https://your-sharepoint-site-url";
string username = "your-username";
string password = "your-password";

ClientContext context = new ClientContext(siteUrl);
context.Credentials = new SharePointOnlineCredentials(username, password);

Make sure to replace “your-sharepoint-site-url”, “your-”, and “your-password” with your actual SharePoint Online site URL, username, and password.

Step 4: Accessing the Document List

Now that we are authenticated, we can access the document list. Add the following code to retrieve all the documents in the list:


List documentsList = context.Web.Lists.GetByTitle("Documents");
context.Load(documentsList);
context.ExecuteQuery();

CamlQuery query = new CamlQuery();
query.ViewXml = "";
ListItemCollection items = documentsList.GetItems(query);
context.Load(items);
context.ExecuteQuery();

foreach (ListItem item in items)
{
    Console.WriteLine(item["FileLeafRef"]);
}

This code retrieves the “Documents” list from SharePoint Online and prints the name of each document in the console. You can modify this code to suit your specific requirements.

Conclusion

By following the outlined in this article, you should now be able to access a SharePoint Online document list through ASP.NET. This opens up a world of possibilities for your web application, allowing you to leverage the power of SharePoint in your development projects.
