C# and arrays of anonymous objects

Question

What does such an expression mean?

obj.DataSource = new[] {     new {Text = "Silverlight", Count = 10, Link="/Tags/Silverlight" },     new {Text = "IIS 7", Count = 11, Link="http://iis.net" },     new {Text = "IE 8", Count = 12, Link="/Tags/IE8" },     new {Text = "C#", Count = 13, Link="/Tags/C#" },     new {Text = "Azure", Count = 13, Link="?Tag=Azure" } }; 

Especially these lines: new {Text = "IIS 7"... }

How can I create an array like this manually to suit this DataSource.

Answer 1

First, let's reformat that code a little:

obj.DataSource = new[] {     new {  Text = "Silverlight",  Count = 10,  Link = "/Tags/Silverlight"  },     new {  Text = "IIS 7",        Count = 11,  Link = "http://iis.net"     },      new {  Text = "IE 8",         Count = 12,  Link = "/Tags/IE8"          },      new {  Text = "C#",           Count = 13,  Link = "/Tags/C#"           },     new {  Text = "Azure",        Count = 13,  Link = "?Tag=Azure"         }  }; 

This does not look like a multi-dimensional array, but rather like an array of 5 objects. These objects inside the array are of an anonymous type, created and initialized using new { ... }.

Concerning your question how you can manually create such an array to suit the data source: you seem to be doing exactly that with the above code.

Answer 2

That's not a multidimensional array. That's an array of objects which have been created using object initializers with anonymous types.
