JavaScriptView Source Request Example

JavaScript does not support generic types or methods.

Parameters

array T: Source array.
startIndex Int32: Offset into array array.
length Int32: Length of array array to copy at startIndex offset.

Type Parameters

T: Type of array.

Return Value

T
An array of data copied from the specified portion of the source array.

Usage Note

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

Remarks

Returned array will be extended as needed to make it the specified length, but it will never be less than the source array length - startIndex.

If an existing array of primitives is already available, using the BlockCopy(Array, Int32, Array, Int32, Int32) directly instead of this extension method may be optimal since this method always allocates a new return array. Unlike BlockCopy(Array, Int32, Array, Int32, Int32), however, this function also works with non-primitive types.

Exceptions

ArgumentOutOfRangeException

startIndex is outside the range of valid indexes for the source array -or- length is less than 0.
