Remarks

The method concatenates each object in values; it does not add any delimiters.

An Empty string is used in place of any null argument.

Concat<T>(IEnumerable<T>) is a convenience method that lets you concatenate each element in an IEnumerable<T> collection without first converting the elements to strings. It is particularly useful with Language-Integrated Query (LINQ) query expressions, as the example illustrates. The string representation of each object in the IEnumerable<T> collection is derived by calling that object's ToString method.

Examples

The following example defines a very simple Animal class that contains the name of an animal and the order to which it belongs. It then defines a List<T> object to contain a number of Animal objects. The Enumerable.Where extension method is called to extract the Animal objects whose Order property equals "Rodent". The result is passed to the Concat<T>(IEnumerable<T>) method and displayed to the console.
