DataRowComparer(Of TRow) Class
Compares two DataRow objects for equivalence by using value-based comparison.
Assembly: System.Data.DataSetExtensions (in System.Data.DataSetExtensions.dll)
Thetype exposes the following members.
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|Equals(TRow, TRow)||Compares two DataRow objects by using a column-by-column, value-based comparison.|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetHashCode(TRow)||Returns a hash code for the specified DataRow object.|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
This class implements the IEqualityComparer(Of 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 is stateless.
This class is sealed and cannot be derived from.
