How to Select Specific Columns

In EF Core you can select specific columns from a database table using the Select() method with an anonymous type. This allows you to specify only the necessary columns, improving performance by reducing unnecessary data retrieval. Here's a sample code snippet:

var query = dbContext.TableName
                .Where(condition)
                .Select(x => new 
                {
                    x.ColumnName1,
                    x.ColumnName2,
                    // Add more columns as needed
                })
                .ToList();

This technique is beneficial for optimizing data retrieval in Entity Framework queries. For more details, refer to the following websites.
