EnumerableRowCollectionExtensions::Cast<TResult> Method

Converts the elements of an EnumerableRowCollection to the specified type. This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Namespace:  System.Data
Assembly:  System.Data.DataSetExtensions (in System.Data.DataSetExtensions.dll)

[ExtensionAttribute]
public:
generic<typename TResult>
static EnumerableRowCollection<TResult>^ Cast(
	EnumerableRowCollection^ source
)

Type Parameters

TResult

The type to convert the elements of source to.

Parameters

source
Type: System.Data::EnumerableRowCollection

The EnumerableRowCollection that contains the elements to be converted.

Return Value

Type: System.Data::EnumerableRowCollection<TResult>
An EnumerableRowCollection that contains each element of the source sequence converted to the specified type.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type EnumerableRowCollection. 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).

ExceptionCondition
ArgumentNullException

source is nullptr.

InvalidCastException

An element in the sequence cannot be cast to type TResult.

This method is implemented by using deferred execution. The immediate return value is an object that stores all the information that is required to perform the action. The query represented by this method is not executed until the object is enumerated either by calling its GetEnumerator method directly or by using foreach in Visual C# or For Each in Visual Basic.
