What is an Excel Range & Cells object?

[David Thielen]

It seems that the Range (and Cells) property are sometimes a single cell and
sometimes an array of cells. Is there anything that goes into the details of
how this is set up?

And how do I know if a given Range object is a single cell and if so, what
it's row & column are?

Hello Dave,

From your post, my understanding on this issue is: you wonder how to set up
an Excel.Range object with multiple cells, how to determine if an Excel
range has a single cell, and how to get its row and column. If I'm off
base, please feel free to let me know.

1. How to set up a range with multiple cells
Excel object model exposes several ways to setup a range with multiple cells
a. Using Range to specify the range in the worksheet
e.g. Excel.Range range1 = worksheet.get_Range("A1", "B2");
b. Using Application.Union to union multiple ranges
e.g. Excel.Range range2 = (Excel.Range)worksheet.Cells[3, 3];
Excel.Range union = application.Union(range1, range2, missing, missing,
missing, missing, missing, missing, missing, missing, missing, missing,
missing, missing, missing, missing, missing, missing, missing, missing,
missing, missing, missing, missing, missing, missing, missing, missing,
missing, missing);
Please *note* that the union of non-adjacent ranges will creae multiple
'Areas' in the Range object. You may want to have a look at the issue:

c.office.developer.vba&mid=a3c53ac4-690d-436b-b469-a60672f784ba&sloc=en-us
to have a clearer picture about the union of non-adjacent ranges.
c. Using Application.Intersect to get the intersections of multiple ranges.
e.g. Excel.Range intersection = application.Intersect(range1,
range2, missing, missing, missing, missing, missing, missing, missing,
missing, missing, missing, missing, missing, missing, missing, missing,
missing, missing, missing, missing, missing, missing, missing, missing,
missing, missing, missing, missing, missing);

2. How to determine if an Excel.Range has a single cell.
To determine if an Excel.Range has a sigle cell, we could use
range.Cells.Count property. If the property equals 1, the range is composed
of only one cell.

3. How to get the row and column of a cell.
When we get the cell object of type Excel.Range (union.Cells[1, 1]), we
could use range.Row and range.Column properties to get the information.

Please let me know if you have any other concerns, or need anything else.

Hi;

My question is a little different. When I get the Application.Selection
object (a Range), how do I access the cells in it - including when it is a
sparse selection? So I am not creating the Range, I get the Range from
Selection and need to know what cells it contains.

Also, can a Range ever include just some of the text in a cell or is a range
always just a collection of cells?

Hello Dave,

Sorry for my misunderstanding of your question. To access the cells in a
selected range, including sparse selection, we need to
1. iterate the Areas of the range, because non-adjacent ranges will be
stored in different areas.
2. iterate the Cells of each Area.

Here is a sample code for your reference:

range = (Excel.Range)application.Selection;
for (int i = 1; i <= range.Areas.Count; i++)
{
Excel.Range area = range.Areas as Excel.Range;
for (int j = 1; j <= area.Rows.Count; j++)
{
for (int k = 1; k <= area.Columns.Count; k++)
{
Excel.Range cell = (Excel.Range)area.Cells[j, k];
Console.WriteLine(cell.Value2);
}
}
}

can a Range ever include just some of the text in a cell or is a
range always just a collection of cells?

If a range is comosed of only one cell, we can access its text by calling
range.Value2 directly. If a range contains multiple cells, we need to use
the above method to reach very cells in it.

If you have any other question, please feel free to let me know.

This is weird (I think) but I think I understand now.
