Сheck that a variable is initialized

[vedro-compota]

Hi guys ))
Please tell me - how to check that a variable is initialized ?
Thanks in advance )

[Narue]

It depends on the type and scope of the variable. Can you be more specific?

[vedro-compota]

yes)I need to check string and int types ))

[Momerath]

int types are always initialized (to zero). You can check if a string type is null ( if (myString == null) { // Not initialized .

In general, a null reference means the variable doesn't have an object.

thank you, Momerath !

>int types are always initialized (to zero).
This misconception is why I asked for a more specific question. As an example, local variables are not automatically initialized, which means there's no way to check them without relying on compiler warnings/errors.

static void Main(string[] args)
{
    int i; // Not initialized (value type)
    string s; // Not initialized (reference type)

    // ...
}

Also, you should use the static String.IsNullOrEmpty method to check for uninitialised strings.

but what is benefit of using static string?

I meant the static method of the String class IsNullOrEmpty , not that the string itself is static. This static method checks whether the string is unitialised or initialised to String.Empty .
