Enumerable::Max<TSource> Method (IEnumerable<TSource>, Func<TSource, Int32>)

Invokes a transform function on each element of a sequence and returns the maximum Int32 value.

Namespace:  System.Linq
Assembly:  System.Core (in System.Core.dll)

No code example is currently available or this language may not be supported.

Type Parameters

TSource

The type of the elements of source.

Parameters

source
Type: System.Collections.Generic::IEnumerable<TSource>
A sequence of values to determine the maximum value of.
selector
Type: System::Func<TSource, Int32>
A transform function to apply to each element.

Return Value

Type: System::Int32
The maximum value in the sequence.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable<TSource>. When you use instance method syntax to call this method, omit the first parameter.

ExceptionCondition
ArgumentNullException

source or selector is nullptr.

InvalidOperationException

source contains no elements.

The Max<TSource>(IEnumerable<TSource>, Func<TSource, Int32>) method uses the Int32 implementation of IComparable<T> to compare values.

You can apply this method to a sequence of arbitrary values if you provide a function, selector, that projects the members of source into a numeric type, specifically Int32.

In Visual Basic query expression syntax, an Aggregate Into Max() clause translates to an invocation of Max.

The following code example demonstrates how to use Max<TSource>(IEnumerable<TSource>, Func<TSource, Int32>) to determine the maximum value in a sequence of projected values.
