你是用字典这个意思吗？把必须踢出去，然后再随机？
Sub suiji()
Dim dic As Object
Dim arr As Variant
Dim brr As Variant
Set dic = CreateObject("scripting.dictionary")
r1 = Range("a1048576").End(xlUp).Row
r2 = Range("b1048576").End(xlUp).Row
arr = Range("a2:a" & r1)
brr = Range("b2:b" & r2)
For i = 1 To UBound(arr, 1)
dic(arr(i, 1)) = ""
Next i
For i = 1 To UBound(brr, 1)
dic.Remove (brr(i, 1))
Next i
Range("c2").Resize(dic.Count, 1) = Application.WorksheetFunction.Transpose(dic.keys)
End Sub
