## Remarks
This class implements the <xref:System.Collections.Generic.IEqualityComparer%601> interface and uses value-based semantics to compare <xref:System.Data.DataRow> objects. This class is required because the default implementations of some set-based operations (such as <xref:System.Linq.Enumerable.Distinct%2A>, <xref:System.Linq.Enumerable.Union%2A>, <xref:System.Linq.Enumerable.Intersect%2A>, and <xref:System.Linq.Enumerable.Except%2A>) use reference-based semantics to compare <xref:System.Data.DataRow> object references, instead of comparing the <xref:System.Data.DataRow> object values. The <xref:System.Data.DataRowComparer%601.Default%2A> class is used to compare the values of the <xref:System.Data.DataRow> objects and does not compare the object references.
This class cannot be directly instantiated. Instead, the <xref:System.Data.DataRowComparer%601.Default%2A> property must be used to return a singleton instance of the <xref:System.Data.DataRowComparer%601.Default%2A> class.
This class is stateless.
This class is sealed and cannot be derived from.
