Erase Statement (Visual Basic)

Visual Studio 2010

Used to release array variables and deallocate the memory used for their elements.

Copy

Erase arraylist

Parts

arraylist: Required. List of array variables to be erased. Multiple variables are separated by commas.

Remarks

The Erase statement can appear only at procedure level. This means you can release arrays inside a procedure but not at class or module level.

The Erase statement is equivalent to assigning Nothing to each array variable.

Example

The following example uses the Erase statement to clear two arrays and free their memory (1000 and 100 storage elements, respectively). The ReDim statement then assigns a new array instance to the three-dimensional array.

Copy


Dim threeDimArray(9, 9, 9), twoDimArray(9, 9) As Integer
Erase threeDimArray, twoDimArray
ReDim threeDimArray(4, 4, 9)
