Converting string to DateTime in C#: complete guide

Hi everyone! I'm new to C# and ran into a problem when working with dates. I have a string, for example "2023-10-15 14:30:00", which I get from a text file. I need to convert it to a DateTime object so I can perform operations — comparison, formatting, calculating the difference between dates.\n\nI tried using Convert.ToDateTime(), but I often get a FormatException. For example, this code:\n\n```csharp\nstring dateString = "15.10.2023";\nDateTime date = Convert.ToDateTime(dateString);\n```\n\nsometimes works, and sometimes doesn't. If the string has the format "2023/10/15", it throws an error. I also tried DateTime.Parse(), but the result is unpredictable. It's especially difficult when strings come in different formats: "October 15, 2023", "15-10-2023" or "2023-10-15T14:30:00Z".\n\nPlease advise how to
