Queryable.Average Method (IQueryable<Nullable<Decimal>>)
Computes the average of a sequence of nullable Decimal values.
Assembly: System.Core (in System.Core.dll)
The MethodCallExpression that represents calling itself. It then passes the MethodCallExpression to the Execute<TResult>(Expression) method of the IQueryProvider represented by the Provider property of the source parameter.method generates a
The query behavior that occurs as a result of executing an expression tree that represents callingdepends on the implementation of the type of the source parameter. The expected behavior is that it calculates the average of the values in source.
The following code example demonstrates how to use Average(IQueryable<Nullable<Int64>>) to calculate the average of a sequence of 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, substitute the elements of the source sequence with elements of the appropriate numerical type.
