Webservice object fail handling

Question

I have a problem regarding try catch when creating an object in C#.

My problem appears when an object is supposed to be created and the webservice which defines the object isn't available or has been modified. That is the problem I would like my program to handle.

When I try to do this:

try
{
    var Customer = new Customer();
}
catch
{
      //handling the exception.
}

Later on in my program I need that particular object, but due to the try catch the object isn't available in all cases (of course when the try fails, the object isn't created).

without if(customer != null)

if (insertCustomer(lead, LS_TS, out Customer) == true)
{
    insert = true;
}

with if(customer != null)

if(customer != null)
{
    if (insertCustomer(lead, LS_TS, out Customer) == true)
    {
        insert = true;
    }
}

No matter what, the compiler says: "The name 'Customer' does not exist in the current context

How do I solve this problem? I need a program to be running all the time and when checking an object which isn't created then I need to exit the method and try again later.

Thanks in advance

You can just do this:

Customer customer = null;

try
{
    customer = new Customer();
}
catch
{
    // handling the exception.
}

and whenever you need to use the object customer you should do this

if(customer != null)
{
    // do stuff
}
