Concatenates two sequences.
Assembly: System.Core (in System.Core.dll)
[ExtensionAttribute] public: generic<typename TSource> static IQueryable<TSource>^ Concat( IQueryable<TSource>^ source1, IEnumerable<TSource>^ source2 )
The type of the elements of the input sequences.
- Type: System.Linq::IQueryable<>
The first sequence to concatenate.
- Type: System.Collections.Generic::IEnumerable<>
The sequence to concatenate to the first sequence.
Return ValueType: System.Linq::IQueryable<>
An IQueryable<T> that contains the concatenated elements of the two input sequences.
Usage NoteIn Visual Basic and C#, you can call this method as an instance method on any object of type IQueryable<>. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
The method generates a MethodCallExpression that represents calling itself as a constructed generic method. It then passes the MethodCallExpression to the CreateQuery<TElement>(Expression) method of the IQueryProvider represented by the Provider property of the source1 parameter.
The query behavior that occurs as a result of executing an expression tree that represents calling depends on the implementation of the type of the source1 parameter. The expected behavior is that the elements in source2 are concatenated to those of source1 to create a new sequence.
