My question is: can I check whether a variable (string or int/double type) or an array (string or int/double type) is initialized in C#?
Thanks in advance.

You are guaranteed some sort of initialization. For any static or instance members, all variables are automatically initialized when the type or instance is constructed, either explicitly or implicitly (in which case
default(Type)is the value, so 0 for numeric types,nullfor strings and other reference types, etc.).For local variables, they cannot be used before declaration, so if you can check it, it’s been initialized.
