 | A LINQ Style Cumulative Moving Average Operator
When working with series of numeric data that include large fluctuations, it can be difficult to spot trends. One way of processing such a series to make it easier is to apply a cumulative moving average. This article describes a LINQ style extension method to calculate such an average. |
| A LINQ Style Simple Moving Average Operator
Raw data series with extreme peaks and troughs can be difficult to interpret. One way to remove sudden spikes is by applying a simple moving average calculation. This article describes a simple moving average extension method with a LINQ style. |
| A LINQ Style Operator to Find Items with Distinct Properties
Language-Integrated Query's (LINQ) Distinct operator removes duplicates from a sequence but does not allow a lambda expression to be used when determining if an item is unique. This article describes a custom extension method for this purpose. |
| Performing Cross Joins with LINQ to Objects
A cross join, also known as a Cartesian product, joins two sequences of values to create a new collection where every possible combined pair is represented. When using Language-Integrated Query (LINQ), cross joins can replace nested loops. |
| LINQ Style Append and Prepend Operators
Integrated Query (LINQ) includes a standard query operator to concatenate two sequences of the same type, but nothing to append or prepend a single item to a collection. However, these useful methods are simple to create. |
| A LINQ Style Operator to Set the Length of a Sequence
Sometimes it is necessary to modify the length of a sequence of values to achieve a fixed length. This may require that values at the end of the sequence are omitted or that new elements are added to achieve the desired length. |
| LINQ Style Variance and Standard Deviation Operators
In statistics, the variance and standard deviation for a set of data indicate how spread out the individual values are. Small values indicate that the elements of a set are close to the average value, whereas larger values suggest a greater spread. |
| A LINQ Style Partition Operator
Sometimes a sequence of values needs to be split into partitions, batches or chunks. This article describes an extension method that performs such an operation, accepting a collection of any type and returning a set of sequences from its contents. |
| A LINQ Style Replace Operator
It can be useful to search a sequence of items for a specific value or object and replace all matching instances with a new value. Language-Integrated Query (LINQ) does not provide a standard query operator for this purpose but creating one is simple. |
| Retrieving Items from the End of a Sequence
Language-Integrated Query (LINQ) provides the Take partitioning operator that extracts items from the start of any sequence. No similar operator is provided to retrieve the items from the end of a sequence. This article describes such a method. |
