Take While Clause (Visual Basic)

Includes elements in a collection as long as a specified condition is true and bypasses the remaining elements.

Syntax

Take While expression  

Parts

Term	Definition
expression	Required. An expression that represents a condition to test elements for. The expression must return a Boolean value or a functional equivalent, such as an Integer to be evaluated as a Boolean.

Remarks

The Take While clause includes elements from the start of a query result until the supplied expression returns false. After the expression returns false, the query will bypass all remaining elements. The expression is ignored for the remaining results.

The Take While clause differs from the Where clause in that the Where clause can be used to include all elements from a query that meet a particular condition. The Take While clause includes elements only until the first time that the condition is not satisfied. The Take While clause is most useful when you are working with an ordered query result.

Example

The following code example uses the Take While clause to retrieve results until the first customer without any orders is found.
