I used to work in VB.NET. Now in C#, I have:
using System;
using System.Data;
using System.Data.SqlClient;

DataRow dr;

Then I want to use dr("ColName") but there is no Item property in the
IntelliSense. What is wrong here?

Thanks.

Why do you need the Item property exactly?

"Item" is the indexer in vb.net.

the default value of c# ~~is the indexer. so your code would look like
this... (aka, you don't have to type in "Item")

myobject.Item(0) --vb.net

myobject[0] // c#

Indexers are accessed in C# by brackets, not parenthesis. Could this be part
of your problem with Intellisense?

dr["ColName"]

Vik,

In C#, you use an indexer. You would do this:

dr["ColName"]

Hope this helps.

Thanks for the replies.

Yes, the problem was that I used VB style dr(...) instead of dr[...].

In VB, an object's default property is listed in IntelliSense. In C#, an
indexer is never shown in IntelliSense?
