Everytime you will call this method with Command object and in response you will get the data in form of DataTable.

What is something in this code which is still not clear?

"ExecuteSelectCommand" is a function which will call in main page code or button code which results a table data. "Command" - a parameter which will pass form a main page or button code where you are using this function.

"ExecuteSelectCommand" function return table that's why it's data type is DataTable.

Coming to "Public" it is a access quantifier in C# indicate you can use this function any where in the program or project where you call this class or object.
