This article delves into common issues with the DateTime.ParseExact method in C# within cross-cultural environments, particularly focusing on parsing errors that occur when date format strings do not align with current cultural settings. Through a case study where the date "01.05.2023 12:00:00" is incorrectly parsed as January 5th instead of May 1st under Dutch culture (nl-NL), the root cause is identified as the incompatibility between the format string "dd.MM.yyyy HH:mm:ss" and the default date format in Dutch culture. The core solution involves using the CultureInfo class to explicitly specify the cultural context, such as CultureInfo("nl-NL"), ensuring parsing adheres to the target culture's date representation conventions. The article also expands on related methods like DateTime.Parse and custom format providers to offer comprehensive technical guidance. With code examples and theoretical analysis, this paper aims to help developers avoid common internationalization pitfalls and enhance application globalization compatibility.
