	this IEnumerable<T> org,
	Func<T, M> conversion
)
where M : Object, IComparable<M>

Parameters

org IEnumerableT: The enumeration to consider.
conversion FuncT, M: Conversion function that converts each element (type: T) of the sequence to a value (of type M that is comparable.

Type Parameters

T: Type of the elements of the enumeration.
M: Type of the value that is used to compare the elements of the sequence.

Return Value

T
This element of the sequence, which by the provided conversion function evaluates to the maximum value.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerableT. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Exceptions

Exception	Condition
InvalidOperationException	The provided enumeration is empty. Thus it is not possible to evaluate the maximum.
