Distinct Results Based on a Specific Field in Linq

Problem:

Obtain distinct results from a database table using Linq based solely on a single field, without retrieving the entire duplicate records.

Answer: Group by Selected Field and Return First Instance

To achieve this, utilize the following query:

table1.GroupBy(x => x.Text).Select(x => x.FirstOrDefault());

This query groups the table by its Text field. Within each group, it selects the first row. Consequently, only unique Text values will be returned as results.
