Normally, I have 2 windows in a split (C-x 3):

We've got an interesting case where we are trying to determine how different instances of our app were launched.

Comparing string in C# is pretty simple. In fact there are several ways to do it. I have listed some in the block below. What I am curious about are the differences between them and when one should be used over the others? Should one be avoided at all costs? Are there more I haven't listed?

how these functions work:
**`stringValue.CompareTo(otherStringValue)`**
1. `null` comes before a string
2. it uses `CultureInfo.CurrentCulture.CompareInfo.Compare`, which means it will use a culture-dependent comparison. This might mean that `ß` will compare equal to `SS` in Germany, or similar

the comparison.
3. Calling `.Equals()` on a `null` string gets `null` reference exception, while on `==` does not.
**`Object.ReferenceEquals(stringValue, otherStringValue)`**
Just checks that references are the same, i.e. it isn't just two strings with the same contents, you're comparing a string object with itself.
