Sort An Array And Remove Duplicates?
Sep 8, 2009I have a semicolon delimited string (e.g. an EMail Address List returned from a database or a textbox). How do I separate the string into an array, sort, and remove duplicates? The code below works to separate the string and sort the results, but doesn't remove the duplicates. I could probably then loop through the array and copy to a new array to eliminate the duplicates, but there must be a better way to do this using the VB.Net Array, String, and Collections handling classes.
Dim s As
String =
"Test; Test8;Test1;Test2;Test3; Test8;Test4;Test5; Test6"

Material: STL TUBG Stock Size: 3" X 3" X 0.250" W/T X 254MM

Material: STL TUBG Stock Size: 3" X 3" X 0.250" W/T X 102MM
Material: STL TUBG Stock Size: 3" X 3" X 0.250" W/T X 102MM
Material: HRS Stock Size: 1" X 4" X 175MM
Material: HRS Stock Size: 1" X 4" X 175MM
Material: HRS Stock Size: 1" X 4" X 175MM
Material: HRS Stock Size: 1" X 4" X 175MM

Flag Duplicates In Array / Data Grid?
Apr 21, 2010I have a huge array, well Data Grid actually (unbound), but it can be populated into an array... 47 columns by 2000 rows. The data within is random, I need to check each row for duplicates...
essence is on the quickest method though as it will be called by the user. The data is populated by column, so I can not check for duplicates during population.
e.g.
DataFR1, DataBF2, DataJU3....... DataXN47
DataHY1, DataBF2, DataJU3....... DataXN47
DataFR1, DataBF2, DataJU3....... DataXN47 << This is a duplicate >>
I can perform the 'compare' but i'm struggling with the speed.. because row 2000 could be the same as row 1 I can only get my head around a solution that would be very slow
