This article explores the uniqueness of GUIDs (Globally Unique Identifiers) through a C# implementation of an efficient collision detection program. It begins by explaining the 128-bit structure of GUIDs and their theoretical non-uniqueness, then details a detection scheme based on multithreading and hash sets, which uses out-of-memory exceptions for control flow and parallel computing to accelerate collision searches. Supplemented by other answers, it discusses the application of the birthday paradox in GUID collision probabilities and the timescales involved in practical computations. Finally, it summarizes the reliability of GUIDs in real-world applications, noting that the detection program is more for theoretical verification than practical use. Written in a technical blog style, the article includes rewritten and optimized code examples for clarity and ease of understanding.
