Enumerable.Max(TSource, TResult) Method (IEnumerable(TSource), Func(TSource, TResult))
Invokes a transform function on each element of a generic sequence and returns the maximum resulting value.
Namespace: System.Linq
Assembly: System.Core (in System.Core.dll)
Type Parameters
- TSource
The type of the elements of source.
- TResult
The type of the value returned by selector.
Parameters
- source
- Type: System.Collections.Generic.IEnumerable(TSource)
A sequence of values to determine the maximum value of.
- selector
- Type: System.Func(TSource, TResult)
A transform function to apply to each element.
Return Value
Type: TResultThe 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.| Exception | Condition |
|---|---|
| ArgumentNullException | source or selector is a null reference (Nothing in Visual Basic). |
If type TResult implements IComparable(T), this method uses that implementation to compare values. Otherwise, if type TResult implements IComparable, that implementation is used to compare values.
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.

This code example uses an overload of this overloaded method that is different from the specific overload that this topic describes. To extend the example to this topic, change the body of the selector function. |
