Getting Unique Records Based on a Specific Field Using Linq

When working with a table, it's often necessary to retrieve unique records based on a specific field to avoid duplication. In this context, you want to use Linq's Distinct method to achieve this.

To use Distinct effectively, you need to specify the field you want to use for uniqueness. The following code demonstrates how to achieve this:

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

In this query, the GroupBy clause groups the records in table1 by the Text field. The Select clause then selects the first record from each group, which ensures that only unique Text values are returned.

As a result, the query will return a new table containing distinct records based solely on the Text field. This is useful for scenarios where you need to eliminate duplicates while still maintaining the integrity and values of the other fields in the table.
