需要在LINQ的DTO中选择不同类型的值

public class MyDTO
{
    public string Name { get; set; }
    public int Age { get; set; }
    public decimal Salary { get; set; }
}

var result = from data in dataSource
             select new MyDTO
             {
                 Name = data.Name,
                 Age = Convert.ToInt32(data.Age),
                 Salary = Convert.ToDecimal(data.Salary)
             };

var result = dataSource.Select(data => new MyDTO
{
    Name = data.Name,
    Age = Convert.ToInt32(data.Age),
    Salary = Convert.ToDecimal(data.Salary)
});
