What methods can be used to determine properties and parameters of objects in a database?

In C#, the following methods are often used to determine properties and parameters of objects related to a database:

• Reflection: allows dynamically obtaining information about properties, methods, and attributes of objects at runtime.

  var properties = typeof(YourEntity).GetProperties();
  foreach(var prop in properties)
  {
      Console.WriteLine($"Property: {prop.Name}, Type: {prop.PropertyType}");
  }
  

• Entity Framework Metadata: if an ORM like Entity Framework is used, you can get model metadata through the context.

  var entityType = context.Model.FindEntityType(typeof(YourEntity));
  var properties = entityType.GetProperties();
  foreach(var prop in properties)
  {
      Console.WriteLine($"Property: {prop.Name}, Column: {prop.GetColumnName()}");
  }
  

• SQL queries to system tables of the database: to obtain information about the structure of tables and their columns.

Thus, the choice of method depends on the technology used and the level of access to the database.
