โ ๏ธ The ๐ข๐ฟ๐ฑ๐ฒ๐ฟ๐๐ operator is used to sort a sequence of elements based on a specified key. When multiple OrderBy calls are chained together, each subsequent call completely reorders the list, discarding the results of the previous call. This means that only the last OrderBy call will have any effect on the final ordering of the sequence.
๐ Using multiple ๐ข๐ฟ๐ฑ๐ฒ๐ฟ๐๐ calls can also lead to performance problems. This is because each OrderBy call performs a full sort of the list, which can be expensive. If you are chaining multiple OrderBy calls together, you are essentially performing multiple full sorts, which can significantly slow down your code.

๐ก Consider a scenario where a class Student overloads the == operator to compare the values of its properties rather than object references. If you use == to check for null, you might not get the expected result, as the overloaded == would compare property values instead of checking for null.
