Concatenates the members of an IEnumerable<T> implementation.
Assembly: mscorlib (in mscorlib.dll)
The type of the members of values.
Return ValueType: System.String

An Empty string is used in place of any null argument.
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.
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 method and displayed to the console.
