Getting Object instance not set to an instance of an object error

Question

I am trying to encrypt user password

CryptoWrapper wrapObj = null;
UserDetails userDetails = dbContext.GetUserDetails();
if (userDetails != null)
{
    if (userDetails.Password !=null && userDetails.Password != "")
    {
       //some code here
       wrapObj.Crypt(userDetails.Password);
    }
}

I am getting "Object instance not set to an instance of an object."

Can someone help me here?

Almost all cases of `NullReferenceException` are the same. Please see "[What is a NullReferenceException in .NET?](http://stackoverflow.com/questions/4660142/what-is-a-nullreferenceexception-in-net)" for some hints. — John Saunders, Jun 05 '14 at 02:40

CryptoWrapper wrapObj = null;

is null and you are trying to use it.

wrapObj.Crypt(userDetails.Password);

You need to create an instance of CryptoWrapper and assign it to wrapObj

CryptoWrapper wrapObj = new CryptoWrapper();

You're setting wrapObj to null, then trying to call a method from it. Not knowing what CryptoWrapper is, you probably need to edit it to

CryptoAnswer wrapObj = new CryptoAnswer();

to initialize it.
