IsNothing

[Jim Heavey]

I am trying to transition from VB.Net - what is the equivalent if the
IsNothing()?

Thanks in advance for your assistance!!!!!!!!!

null ?

if (someRefType == null)
{
blah blah yackey smacky bork bork;
}

If you are testing:

If variableName Is Nothing Then

the equivalent is

if(variableName == null)
{
}

There is no direct, 100% equivalent of the function IsNothing, but the test
against null accomplishes the same thing.

NOTE: For some objects, there are IsNull() methods. For example, SQL data
types:

if(mySqlInt.IsNull())
{
}

You can also test a dataRow in this manner

if(myDataRow.IsNull())
{
}

i've sometimes had to use if (null == myObject), for instance strings were
broken in vs2002.

Does anybody have any comments on whether this should ever be necessary,
whether this should be the preferred style of IsNothing, etc??

TIA

Well, they might have appeared broken in the debugger, but they did
actually work in .NET itself, AFAIK.

I don't believe it should ever be necessary, and I personally don't
like it, but there we go.
