"C# OleDbDataReader Version "

I couldn't find the property "Item" within this class ? I checked the documentation , it says , it's there ! Where the hell it's hiding ?
I just checked Object browser and didn't find it there , Which one should I believe MSDN or OB ?

what confuses me now is : I can view it in VB but not in C# !

Sorry, I'm really not that familar with database stuff (never bothered to learn it yet).

Hmm, when I set my MSDN filter to 'C# and Related', here's what I got for the Item property (Its quite different from VB's documentation):

OleDbDataReader.Item Property [C#]See Also
OleDbDataReader Class | OleDbDataReader Members | System.Data.OleDb Namespace
Language
C#

C++

JScript

Visual Basic

Show All
Gets the value of a column in its native format.

[C#] In C#, this property is the indexer for the OleDbDataReader class.

Overload List
Gets the value of the specified column in its native format given the column name.

[Visual Basic] Overloads Public Default ReadOnly Property Item(String) As Object Implements IDataRecord.Item
[C#] public object this[string] {get;}
[C++] public: __property Object* get_Item(String*);
[JScript] OleDbDataReader.Item (String)
Gets the value of the specified column in its native format given the column ordinal.

[Visual Basic] Overloads Public Default ReadOnly Property Item(Integer) As Object Implements IDataRecord.Item
[C#] public object this[int] {get;}
[C++] public: __property Object* get_Item(int);
[JScript] OleDbDataReader.Item (int)

Hmm, It'll be easier to read if you checked with MSDN yourself. However, this is indeed very odd.

[Pirate]

It's . I think it has to do with this indexer thing , what the hell is that anyways ?

[pvb]

An indexer in C# is equivalent to the Item property in VB.NET.
e.g.

Dim sColName As String
Dim dr As SqlDataReader
' datareader initialized and loaded up here.
sColName = dr.Item("ColName").ToString()

in c# you'd use the following

string sColName;
SqlDataReader dr;
sColName = dr["ColName"].ToString() 

if you're used to vb 6.0 it's similar to the setting up the Item property of a collection as the default property:

MyCollection.Item(0)
'if Item was the default property for MyCollection then the following would be equal
MyCollection(0)

Never mind , figured it out ! I've used GetValue , it suppose to work the same as Item in VB.NET version !
