Hello everyone,

I am retrieving record from a field in the database, the format of the field record is: Attr_8964_1, the first two parts remains the same, but the last part is auto incremented i.e. 1,2,3, etc, how can i split to get the last auto incremented part while retrieving with data reader?

i tried using list, but didnt know how, below is my code:

C#

listAttributeRegion.Add(reader["RegionName"].ToString().Split("_"));

but it is not working, any assistance will be apprciated.

Thanks in advance

Can you show us why this isn't working and what you should be getting?

The error message is:Aurgument type string is not assignable to parameter type char,

ListAttributeRegion is a list, this is how i declare it: var listAttributeRegion = new List<string>();

as I mentioned in the solution you should change "_" to '_'

Solution 1

if you are sure that all the values have the same format you could use the following code instead of yours

C#

listAttributeRegion.Add(reader["RegionName"].ToString().Split('_')[2]);
