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.
