array redim and redim preserve

  Thanks for your information

  Sadly, Microsoft were forced to preserve a lot of VB6 *** in VB.NET. Read this link:

  and then consider throwing this rubbish away in favour of a proper dynamic array.

  As Christian said, you should use a proper dynamic array such as ArrayList, but here is a translation:

  object[] vaResultSet = null;

  if (vaResultSet == null)
  vaResultSet = new object[1];
  else
  {
  //INSTANT C# NOTE: The following 4 lines reproduce what 'ReDim Preserve' does behind the scenes in VB.NET:
  //ORIGINAL LINE: ReDim Preserve vaResultSet(UBound(vaResultSet) + 1)
  object[] tempReDim1 = new object[vaResultSet.GetUpperBound(0) + 2];
  if (vaResultSet != null)
  System.Array.Copy(vaResultSet, tempReDim1, System.Math.Min(vaResultSet.Length, tempReDim1.Length));
  vaResultSet = tempReDim1;
  }
