 | CondensedCollectionExtensionsMinTSource, TResult Method (CondensedCollectionTSource, FuncTSource, TResult) |
[This is preliminary documentation and is subject to change.]
Invokes a transform function on each element of a generic sequence and returns the minimum resulting value. Optimized for a CondensedCollection.
Namespace: Condensed.Linq
Assembly: Condensed (in Condensed.dll) Version: 0.1.0.0 (0.1.0.0)
Syntaxpublic static TResult Min<TSource, TResult>( this CondensedCollection<TSource> source, Func<TSource, TResult> selector )
Parameters
- source
- Type: CondensedCondensedCollectionTSource
A sequence of values to determine the minimum value of. - selector
- Type: SystemFuncTSource, TResult
A transform function to apply to each element.
Type Parameters
- TSource
- The type of the elements of source.
- TResult
- The type of the value returned by selector.
Return Value
Type: TResultThe minimum value in the sequence or, if TSource is reference type, null if source is empty or contains only null values.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type CondensedCollectionTSource. 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 |
|---|---|
| ArgumentNullException | source is null |
| InvalidOperationException | TResult is a value type and the source collection contains no elements |
Remarks
This implementation of Min() is specialized for a CondensedCollection and tries to
take advantage of the CondensedCollection's knowledge of unique values in order to improve performance.
If you would rather use the normal LINQ extension method then cast the CondensedCollection to an IListT
to use the MaxTSource, TResult(IEnumerableTSource, FuncTSource, TResult) implementation.
