Enumerable.Max<'TSource> Method (IEnumerable<'TSource>, Func<'TSource, Nullable<Single>>)
Invokes a transform function on each element of a sequence and returns the maximum nullable Single value.
Assembly: System.Core (in System.Core.dll)
static member Max<'TSource> : source:IEnumerable<'TSource> * selector:Func<'TSource, Nullable<float32>> -> Nullable<float32>
A sequence of values to determine the maximum value of.
Return ValueType: System.Nullable<Single>
The value of type Nullable<Single> in C# or Nullable(Of Single) in Visual Basic that corresponds to the maximum value in the sequence.
The type of the elements of source.
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 Nullable<Single> in C# or Nullable(Of Single) in Visual Basic.
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.
