The concepts of "rows" and "columns" suggests only two-dimensional arrays,
but there can actually be many more.

To get the number of dimensions you can use

int dimensions = myArray.Rank;

To check how "big" each dimension is you have e.g. the method GetUpperBound
which takes the "dimension" as argument.

But let's say that you only have just two dimensions, and want to know how
many "rows" there are, you check the "first dimension":

int rows = myArray.GetUppe rBound(0) + 1;

For other things you can do with an array:

Hi Suppose we have an array of DataRows e.g. Dim drMyRows() As DataRow = myTable.Rows(0).GetChildRows("PricesCompany") generated via a relationship. The question I have is this. Isn't this in essence a table i.e. a collection of rows? The reason I ask is that I wanted to extract from the array of rows

Hi all, Would someone be able to tell me the most 'graceful' way of removing unwanted rows from a dataset based on a condition prior to update? OR, resetting the rows all to unchanged after they are initally added to the recordset. I create a dataset, which begins empty after the initial .Fill. Then I create several rows with some default information, leaving one

I populate the datagrid, resize it accordingly and it works fine...just when I click the headers is when it messes up. It would be fine if I could run my autosizing again after the sorting is done since there...
