Queryable.SkipWhile<'TSource> Method (IQueryable<'TSource>, Expression<Func<'TSource, Boolean>>)

 

Bypasses elements in a sequence as long as a specified condition is true and then returns the remaining elements.

Namespace:   System.Linq
Assembly:  System.Core (in System.Core.dll)

static member SkipWhile<'TSource> : 
        source:IQueryable<'TSource> *
        predicate:Expression<Func<'TSource, bool>> -> IQueryable<'TSource>

Parameters

source
Type: System.Linq.IQueryable<'TSource>

An IQueryable<'T> to return elements from.

predicate
Type: System.Linq.Expressions.Expression<Func<'TSource, Boolean>>

A function to test each element for a condition.

Return Value

Type: System.Linq.IQueryable<'TSource>

An IQueryable<'T> that contains elements from source starting at the first element in the linear series that does not pass the test specified by predicate.

Type Parameters

TSource

The type of the elements of source.

Exception Condition
ArgumentNullException

source or predicate is null.

This method has at least one parameter of type Expression<'TDelegate> whose type argument is one of the Func<'T, 'TResult> types. For these parameters, you can pass in a lambda expression and it will be compiled to an Expression<'TDelegate>.

The SkipWhile<'TSource>(IQueryable<'TSource>, Expression<Func<'TSource, Boolean>>) method generates a MethodCallExpression that represents calling SkipWhile<'TSource>(IQueryable<'TSource>, Expression<Func<'TSource, Boolean>>) itself as a constructed generic method. It then passes the MethodCallExpression to the CreateQuery(Expression) method of the IQueryProvider represented by the Provider property of the source parameter.

The query behavior that occurs as a result of executing an expression tree that represents calling SkipWhile<'TSource>(IQueryable<'TSource>, Expression<Func<'TSource, Boolean>>) depends on the implementation of the type of the source parameter. The expected behavior is that it applies predicate to each element in source until it finds an element for which predicate returns false. That element and all the remaining elements are returned.

The following code example demonstrates how to use SkipWhile<'TSource>(IQueryable<'TSource>, Expression<Func<'TSource, Boolean>>) to skip elements of an array as long as a condition is true.
