VB中怎么释放变量所占有的内存空间

Answer 1

set xxx=nothing就是把对象占用的空间释放掉。
其他的局部变量都在栈内存，用完会自动释放的

Answer 2

Dim NumArray(10) As Integer ' Integer array.
Dim StrVarArray(10) As String ' Variable-string array.
Dim StrFixArray(10) As String * 10 ' Fixed-string array.
Dim VarArray(10) As Variant ' Variant array.
Dim DynamicArray() As Integer ' Dynamic array.
ReDim DynamicArray(10) ' Allocate storage space.
Erase NumArray ' Each element set to 0.
Erase StrVarArray ' Each element set to zero-length
' string ("").
Erase StrFixArray ' Each element set to 0.
Erase VarArray ' Each element set to Empty.
Erase DynamicArray ' Free memory used by array.
