Answered GetType()

[Anburaj Marikkani]

Hi,

I have a class(MyClass) it is inherited from DataTable class.

Class MyClass : DataTable {
}

And I bind this class to my grid. In our source, there is a condition which checks

grid.Datasource.GetType.Name=="DataTable"

But in my case, the Datasource type name has MyClass then how can I achieve without modifying the condition

The condition only allows "DataTable" and no inheritance. If condition can't change then you can only use DataTable and not other class.

And if the condition can be changed, it can be changed to

typeof(DataTable).IsAssignableFrom(grid.DataSource.GetType())

 

[Skydiver]

I would recommend exercising extreme caution about restricting the type to just DataTable and it's descendants. See the documentation for the list of other types supported by the DataSource property:

DataGridView.DataSource Property (System.Windows.Forms)

Gets or sets the data source that the DataGridView is displaying data for.

And if the condition can be changed, it can be changed to

typeof(DataTable).IsAssignableFrom(grid.DataSource.GetType())

or Is operator: Type-testing operators and cast expression - C# reference
