C# 0 The Complete Reference

CopyInsert( )

 would not compile because 

int

 is a value type, not a reference type:

// Now wrong because T must be reference type!

ArrayUtils.CopyInsert(99, 2, nums, nums2); // Now illegal!

Generic Delegates

Like methods, delegates can also be generic. To declare a generic delegate, use this general 

form:

delegate

ret-type delegate-name

<

type-parameter-list

>(

arg-list

);

Notice the placement of the type parameter list. It immediately follows the delegate’s name. 

The advantage of generic delegates is that they let you define, in a type-safe manner, a 

generalized form that can then be matched to any compatible method.

The following program demonstrates a generic delegate called 

SomeOp

that has one 

type parameter called
