I can't give you the in-depth reasons off-hand, but it's something to do with the variables not being instantiated - they exist but do not point to any objects. Strings are a bit of a special case. Remember that there is a big difference between Nothing and an empty string.

Try this code:

Dim f1 As String = ""
        Dim f2 As String = ""
 
        MsgBox(f2.GetType.ToString)

hi trisuglow

I have tried the code u suggested but the error is same as previous i.e

An unhandled exception of type 'System.NullReferenceException' occurred in temp.exe

Additional information: Object reference not set to an instance of an object.

I have to get the type of variable which i have declared regardless of null or empty.

Please guide me if u have ant different solution


Thanks & regards

Just to comment something about string . String objects are reference type and should be initialized (at least in C#) . This example will work even if the variable isn't initialized because it's value type and its value set to 0 at creation time .

Dim i As Integer
MsgBox(i.GetType.ToString)

Reference types are assigned null values after instantiation (spell?? ) .
