Enumerable.Sum Method (IEnumerable<Int32>)
Computes the sum of a sequence of Int32 values.
Assembly: System.Core (in System.Core.dll)
Return ValueType: System.Int32
The sum of the values in the sequence.
Usage NoteIn Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable<Int32>. When you use instance method syntax to call this method, omit the first parameter.
This method returns zero if source contains no elements.
In Visual Basic query expression syntax, an Aggregate Into Sum() clause translates to an invocation of Sum.
The following code example demonstrates how to use Sum(IEnumerable<Single>) to sum the values of a sequence.
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, substitute the elements of the source sequence with elements of the appropriate numerical type.
