BindingSource for Windows Forms

Question

Hi
I wonder if anyone can help me i am stuck on trying to retrieve a current value from a Bindingsource which has only one row. I have recently moved from VB to C# and i had it working perfectly in VB. My project is a windows application.
The vb code that worked for me was
greeting.Text = "Good Morning" & " " & Me.PersonBindingSource.Current("firstname").ToString & ""
I tried the following in C#
lbl_greeting.Text = personBindingSource.Current("firstname".ToString().ToString());
except it keeps throwing up
Non-Invocable member 'systems.windows.forms.bindingsource.current' cannot be used like a method.
Please can someone help me out. I would be very greatfull!
Thanks

in C# you have to cast the current property check this: http://www.lehmkuhl.za.net/blog/post/2008/01/09/Accessing-fields-in-the-BindingSourceCurrent-property.aspx http://msdn.microsoft.com/en-us/library/system.windows.forms.bindingsource.current.aspx

I have tried this .personBindingSource.Current[ firstname ] and it doesnt work. This time the error is 'cannot apply indexing with [ ] to an expression of type 'object' as for the code tips it doesnt say anything for current except that it retrieves the current value. I guess im not going to get this done. thanks

i have learnt c# not vb .. but i think this may be a bracket problem.. ths brcket (...........) used for methods.. and for datasource [....] is used... try this .personBindingSource.Current[ firstname ]

hi thanks for your reply the example i gave above was from vb the one below is the one from C# i am using this and it is still bringing up the error i mentioned above lbl_greeting.Text = this .personBindingSource.Current( firstname .ToString().ToString()); I have 3 columns in my personBindingSource and i want to retrieve the current value in the firstname column i know i can bind my textbox to this datasource however i need to process the results i get back from the firstname column so this is the best way for me to do it. Is it simply a Syntax?
