CondensedCollectionExtensionsSum Method (CondensedCollectionInt32)

[This is preliminary documentation and is subject to change.]

Computes the sum of a sequence of Int32 values. Optimized for a CondensedCollection.

Namespace:  Condensed.Linq
Assembly:  Condensed (in Condensed.dll) Version: 0.1.0.0 (0.1.0.0)
Syntax
Copy
public static int Sum(
	this CondensedCollection<int> source
)

Parameters

source
Type: CondensedCondensedCollectionInt32
A CondensedCollection of Int32 values to calculate the sum of.

Return Value

Type: Int32
The sum 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 CondensedCollectionInt32. 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
ExceptionCondition
ArgumentNullExceptionsource is null
OverflowExceptionThe sum of the elements in the sequence is larger than Int32.MaxValue.
Remarks
This implementation of Sum() 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 Sum(IEnumerableInt32) implementation.
