C＃检查剪贴板是否有效地包含重复项

Question

I have a code that copies 30 strings to a clipboard at a time from a data source that gets updated randomly; some times over a hundred new strings in under a second and some times there are no updates for a few minutes. I want to send all the strings over sockets to a database. What would be the most efficient approach to sending the strings over sockets with out sending duplicates?

Answer 1

An easy but yet efficient way would be to check for and remove duplicates using LINQ right before you send your strings to the DB:

string[] original; //the array where all the string from your clipboard are in

string[] newStrings = original.Distinct().ToArray();

This way you eliminate all duplicate strings from original .
