Scope and Variable Lifetime in C# | Metrik Rule

Every variable you declare has a scope — the region of code where it exists. Once execution leaves that region, the variable is gone. This lesson explains how scope works in C# and why the compiler sometimes tells you a variable "does not exist in the current context."

We cover method scope (each method gets its own workspace), block scope inside if statements and loops, how parameters are scoped, and the simple fix for most scope errors. All of these are compile-time checks in C#, which means you find out immediately — not in the middle of a demo.
