Question

Im using c# .net windows form application. I have loaded names of all the tables present in a database into a combobox.

Now i need to display the contents of the selected table name.

Normally we use

SqlDataAdapter adp= new SqlDataAdapter(“Select * from employee”, con);

This works fine. but instead of explicitly giving table name i.e employee
i need to set it to combobox1.selected item.

I have given like this its not working:
string filename= combobox1.selecteditem;
SqlDataAdapter adp= new SqlDataAdapter(“Select * from filename”, con);

How can I select filename dynamically?

Answer 1

Just use string concatenation, if you’re not afraid of SQL injection:

SqlDataAdapter adp = new SqlDataAdapter("Select * from " +  combobox1.selecteditem, con);
