Pretty Print Array of Arrays in .NET C#

I had a need to pretty-print an array of arrays while parsing some JSON recently. I couldn't find anything I liked, so I thought I'd post what I ended up with here to save others some time.

Example Output:

public string PrettyPrintArrayOfArrays(int[][] arrayOfArrays) { if (arrayOfArrays == null) return ""; var prettyArrays = new string[arrayOfArrays.Length]; for (int i = 0; i < arrayOfArrays.Length; i++) { prettyArrays[i] = "[" + String.Join(",", arrayOfArrays[i]) + "]"; } return "[" + String.Join(",", prettyArrays) + "]"; }

Hope this helps,

Flatten HTML Document to List of Tags, Attributes, and Values

I had a need to flatten a set of HTML documents to a list of the HTML tags in their head sections.  I thought this bit of code might be useful for someone in the future.

This uses the CsQuery library which is a port of jQuery in C#:
CsQuery also has a NuGet Package:

//Note: Get HTML from somewhere...
var html = "";

var cq = CsQuery.CQ.Create(html);

var head = cq["head"];

var nonScriptHeadTagsQuery =
from t in head.Children()
t.NodeName != "SCRIPT"
&& t.NodeName != "LINK"
select new { Tag = t, TagId = Guid.NewGuid() };

var nonScriptHeadTags = nonScriptHeadTagsQuery.ToList();

var htmlTags =
.SelectMany(tagInfo => tagInfo.Tag.Attributes, (tagInfo, attribute) => new { TagInfo = tagInfo, Attribute = attribute })
.Select(x => new
TagId = x.TagInfo.TagId,
TagType = x.TagInfo.Tag.NodeName,
AttributeName = x.Attribute.Key,
AttributeValue = x.Attribute.Value,

ASP.NET MVC 4 Bulk Add New Users

ASP.NET MVC 4 Membership Overview:

I recently developed a website to replace the built in ASP.NET Configuration Website Administration Tool provided by Microsoft and Visual Studio.

Source available here:

Direct link to download source code:

This tool has the ability to add new users to a ASP.NET MVC 4 website in bulk.  For example, if you have a list of usernames and passwords that you want to set up new accounts for, you can use the "Bulk Add New Users" functionality.

Users can also be added to Roles via this page.  Multiple Roles are separated by spaces.

Updated for ASP.NET MVC 5 and Identity 2.0. Includes an Azure Site Extension:

ASP.NET MVC 4 Membership Overview:

The built in ASP.NET Configuration Website Administration Tool provided by Microsoft and Visual Studio left something to be desired. I have developed an alternative that can be used with ASP.NET MVC 4 SimpleMembershipProvider.

Code available here:

  - Add New Users
  - Bulk Add New Users
  - Search Users
  - Add New Roles
  - Edit Existing Users
  - Reset User Password (on Edit User page)
  - Add Users to Roles
  - Remove Users from Roles
