 | CondensedCollectionExtensionsAverage Method (CondensedCollectionInt64) |
[This is preliminary documentation and is subject to change.]
Computes the average of a sequence of Int64 values. Optimized for a CondensedCollection.
Namespace: Condensed.Linq
Assembly: Condensed (in Condensed.dll) Version: 0.1.0.0 (0.1.0.0)
SyntaxParameters
- source
- Type: CondensedCondensedCollectionInt64
A CondensedCollection of Int64 values to calculate the average of.
Return Value
Type: DoubleThe average of the sequence of values.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type CondensedCollectionInt64. 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 | source contains no elements |
| OverflowException | The sum of the elements in the sequence is larger than Int64.MaxValue. |
Remarks
This implementation of Average() 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 Average(IEnumerableInt64) implementation.
