What is the Find method?

Rating:

The Find method of the DataRelationCollection class is used to get a specified row from a collection of DataRow objects. The DataRowCollection class contains two overloaded versions of the Find method. Their signatures are as follows:

• Overloads Public Function Find(Object) As DataRow
  
  It accepts a primary key value and returns a DataRow object containing the specified primary key value.



• Overloads Public Function Find(Object()) As DataRow
  
  It accepts an array of primary key values of the DataRow object and returns an array of DataRow objects containing the specified primary key values.

The Find method can only be used if the DataTable object to which the DataRowCollection object belongs to has a primary key column. An exception of type MissingPrimaryKeyException is thrown if the Find method is invoked to access a row in a table that has no primary key column.
