IndexOutOfRangeException of DataRow

IndexOutOfRangeException of DataRow

IndexOutOfRangeException of DataRow

I'm using in memory DataTable and I would check if a specific value exist in the table (using the primary key already defined) to update a record.

I have a table named Test with 2 different field: test_id and number_occurrences

Dim record_to_find(() as DataRow
record_to_find = test_table.Select("Test_id" = value_to_be_find)

if (test to check if value_to_be_find" has been found in the DataTable) then
' updating the table
record_to_find(0)("number_occurrences") = 100
DO nothing
End If

this because not only value_to_be_find are present into the DataTable, before update table I should check if the select has returned a valid record, because otherwise I get an IndexOutOfRangeException error.
I tried different solution but I'm not able to execute the update only for the found record.



RE: IndexOutOfRangeException of DataRow

It looks like record_to_find is an array, so use the Length property of the Array class.

Change this

if (test to check if value_to_be_find" has been found in the DataTable) then

to this

If record_to_find.Length > 0 Then 'if no records are found, the array length will be zero

RE: IndexOutOfRangeException of DataRow

I found the solution using GetUpperBound(0)<> -1, and it works fine.
