Download Attachments from SharePoint List Programmatically

This code is a C# version of my earlier post: Download All Attachments from SharePoint List Items using PowerShell

Download attachments from SharePoint list using C# Object model:

String SiteURL;
String ListName;
String downloadLocation;

//Get all inputs
Console.WriteLine("Enter the Site URL:");
SiteURL = Console.ReadLine();
Console.WriteLine("Enter the List Name:");
ListName = Console.ReadLine();
Console.WriteLine("Enter the Download Location:");
downloadLocation = Console.ReadLine();

using (SPSite oSPsite = new SPSite(SiteURL))
	using (SPWeb oSPWeb = oSPsite.OpenWeb())
		oSPWeb.AllowUnsafeUpdates = true;

		//Get the List
		SPList list = oSPWeb.Lists[ListName];
		//Get all list items
		SPListItemCollection itemCollection = list.Items;

		//Loop through each list item
		foreach (SPListItem item in itemCollection)
			string destinationFolder = downloadLocation + "\\" + item.ID;
			if (!Directory.Exists(destinationFolder))

			//Get all attachments
			SPAttachmentCollection attachmentsColl = item.Attachments;
			//Loop through each attachment
			foreach (string attachment in attachmentsColl)
				SPFile file = oSPWeb.GetFile(attachmentsColl.UrlPrefix + attachment);
				string filePath = destinationFolder + "\\" + attachment;

				byte[] binFile = file.OpenBinary();
				System.IO.FileStream fs = System.IO.File.Create(filePath);
				fs.Write(binFile, 0, binFile.Length);


Console.WriteLine("Downloaded all attachments!");

This code downloads all attachments from SharePoint list items.
