DataRowComparer<TRow> Class

Definition

Compares two DataRow objects for equivalence by using value-based comparison.

public sealed class DataRowComparer<TRow> : System.Collections.Generic.IEqualityComparer<TRow> where TRow : DataRow
Type Parameters
TRow

The type of objects to be compared, typically DataRow.

Inheritance
DataRowComparer<TRow>
Implements

Remarks

This class implements the IEqualityComparer<T> interface and uses value-based semantics to compare DataRow objects. This class is required because the default implementations of some set-based operations (such as Distinct, Union, Intersect, and Except) use reference-based semantics to compare DataRow object references, instead of comparing the DataRow object values. The Default class is used to compare the values of the DataRow objects and does not compare the object references.

This class cannot be directly instantiated. Instead, the Default property must be used to return a singleton instance of the Default class.

This class is stateless.

This class is sealed and cannot be derived from.

Properties

Default

Gets a singleton instance of DataRowComparer<TRow>. This property is read-only.
