2つの文字列配列を比較し、それぞれの違いを良いパフォーマンスで返す

Question

私は2つの拡張可能な配列に文字列を持っています。

私の配列が似ていると言うことができます：アレイ2

と比較すると、他の3種類の配列が私に配列1の違いを与える必要があります

ARRAY - 4  ARRAY - 5  ARRAY - 6 
    a9    a4    a1 
    a12    a8    a2 
            a3 
            a10 
            a11 

：として私は結果を取得したい

ARRAY - 1  ARRAY - 2 
    a1    a1 
    a2    a2 
    a3    a3 
    a9    a4 
    a10    a8 
    a11    a10 
    a12    a11 

-array4 here gives the strings that is included in array1 but not found in array2 
-array5 here gives the strings that is included in array2 but not found in array1 
-array6 here gives the strings that is found in both 

このコードは、

です。

i = 0 
j = 0 

For Each innerElement1 In CompareElement1 'CompareElement1 is the array1 here 

    NoneFound = 1 

    'Ones thats in first element also found in second element.. 
    For Each innerElement2 In CompareElement2 'CompareElement2 is the array2 here 

     If innerElement1 = innerElement2 Then 

      'Expand array 
      ReDim Preserve IncludedInBoth(0 To UBound(IncludedInBoth) + 1) 
      IncludedInBoth(i) = innerElement1 
      'Item found in both so NoneFound is 0. 
      NoneFound = 0 
      i = i + 1 

     End If 

    Next 

    'Ones thats in first element but not found in second element.. 
    If NoneFound = 1 Then 

     'Expand array 
     ReDim Preserve NotIncludedInElem2(0 To UBound(NotIncludedInElem2) + 1) 
     NotIncludedInElem2(j) = innerElement1 
     j = j + 1 

    End If 

Next 

'Seperate Comparison for the ones that found in second element _ 
but not found in first element.. 
i = 0 

For Each innerElement1 In CompareElement2 

    NoneFound = 1 

    'Ones thats in second element also found in first element. 
    For Each innerElement2 In IncludedInBoth 

     If innerElement1 = innerElement2 Then 

      'Item found in both so NoneFound is 0. 
      NoneFound = 0 

     End If 

    Next 

    'Ones thats in second element but not found in first element.. 
    If NoneFound = 1 Then 

     'Expand array 
     ReDim Preserve NotIncludedInElem1(0 To UBound(NotIncludedInElem1) + 1) 
     NotIncludedInElem1(i) = innerElement1 
     i = i + 1 

    End If 

Next 

私のコードは正確に比較して真の答えを与えますが、内部のfor eachコールによって引き起こされるパフォーマンスの欠如により、これをより高速な方法と比較する方法がありますか？ 、データの量と

array1 and array2 are two different sized arrays that contains thousands(~100.000)of strings in each. 
also they are not in order. i would like to learn how to order them alphabetically.

テーブルへのデータベース、負荷を作成し、SQLを使用します。永遠のようなその撮影は、この比較も..

少し注意を終了します。それは手動で行うのが遅すぎます。
