I want to remove duplicates from this list:

```
List<Dictionary<string, object>> val = new List<Dictionary<string, object>>();

```

It does not work if I apply Distinct() in this way:

```
 List<Dictionary<string, object>> result = val.Distinct().ToList<Dictionary<string, object>>()

```

Update: Problem is now solved. I used the MySQL union command to read table from the database.
