dbnull

Hi all,

(LocalVariable)ABC.string(Name)= (Idatareader)datareader.GetString(0);

this name value is coming from database.. what happening here is if this name value is null while reading it's throwing an exception?

I am manually doing some if condition here. I don't want to write a manual condition to check all my variables..

I am doing something like this now..

string abc =  (Idatareader)datareader.GetValue(0);
if(abc = null)
    //assiging null
else
    assiging abc value

is there something like can we write extension method for this? thanks

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More

edit4: wikified, since this seems to have morphed more into a discussion than a specific question.
