Enumerable::Min<TSource> Method (IEnumerable<TSource>^, Func<TSource, Int64>^)
Invokes a transform function on each element of a sequence and returns the minimum Int64 value.
Assembly: System.Core (in System.Core.dll)
public: generic<typename TSource> [ExtensionAttribute] static long long Min( IEnumerable<TSource>^ source, Func<TSource, long long>^ selector )
Parameters
- source
-
Type:
System.Collections.Generic::IEnumerable<TSource>^
A sequence of values to determine the minimum value of.
- selector
-
Type:
System::Func<TSource, Int64>^
A transform function to apply to each element.
Type Parameters
- TSource
The type of the elements of source.
| Exception | Condition |
|---|---|
| ArgumentNullException | source or selector is null. |
| InvalidOperationException | source contains no elements. |
The Min<TSource>(IEnumerable<TSource>^, Func<TSource, Int64>^) method uses the Int64 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 Int64.
In Visual Basic query expression syntax, an Aggregate Into Min() clause translates to an invocation of Min.
The following code example demonstrates how to use Min<TSource>(IEnumerable<TSource>^, Func<TSource, Int32>^) to determine the minimum 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. |
