public static void Clear(Array 

a

, int 

star t

,

                                 int 

count

)

Sets the specified elements of 

a

 to zero, 

null

, or 

false

, depending on whether 

the element type is a value type, a reference type, or Boolean. The elements 

to be zeroed begin at the index specified by 

star t

 and run for 

count

 elements. 

public object Clone( )

Returns a copy of the invoking array. The copy refers to the same elements 

as does the original. This is called a “shallow copy.” Thus, changes to the 

elements affect both arrays since they both use the same elements.

public static void

    ConstrainedCopy(Array 

source

, int 

srcIdx

,

                              Array 

dest

, int 

destIdx

,

                              int 

count

)

Copies

count

 elements from 

source

 (beginning at 

srcIdx

) to 

dest

 (beginning 

at

destIdx

). If both arrays are reference types, then 

ConstrainedCopy( )

makes a “shallow copy,” which means that both arrays will refer to the same 

elements. If an error occurs during the copy, 

dest

 is unchanged. 

public static TTo[ ]

    Conver tAll(TFrom[ ] 

a

,

               Conver ter 

conv

)

Conver ts 

a

 from type 

TFrom

 to 

TTo

 and returns the resulting array. The 

original array is unaffected. The conversion is per formed by the specified 

conver ter. 

public static void Copy(Array 

source

,

                                  Array 

dest

,

                                   int 

count

)

Beginning at the star t of each array, copies 

count

 elements from 

source

 to 

dest.

 When both arrays are reference types, then 

Copy( )

 makes a “shallow 

copy,” which means that both arrays will refer to the same elements. If an 

error occurs during the copy, 

dest

 is undefined.

source

,

                                 Array 

dest

,

                                 long 

count

)

Beginning at the star t of each array, copies 

count

 elements from 

source

 to 

dest.

 When both arrays are reference types, then 

Copy( )

 makes a “shallow 

copy,” which means that both arrays will refer to the same elements. If an 

error occurs during the copy, 

dest

 is undefined.
