I’ve just made another tiny addition to my extension method class \/ project<\/a>, adding a small, but maybe useful method:<\/p>\n

This is how to use it to consume an IEnumerable<T> multiple times:<\/p>\n
\r\nvar range = Enumerable.Range(1, 5);\r\nforeach (var i in range.Repeated(5))\r\n{\r\n    \/\/ doing something with i, which will be the sequence\r\n    \/\/ from 1 to 5, repeated 5 times\r\n}\r\n<\/pre>\n
It’s not a big deal, but maybe it’s helpful anyway. Btw, the source code<\/a> is updated, too.<\/p>\n","protected":false},"excerpt":{"rendered":"
