Problems and Solutions of string sorting in C #

Let's talk about the problem first. Simply put, it is a set of data.

String[] data =  ,,,,,,,,,

I want to sort strings and sort the strings. I should think of it as sorting by comparing the size of a single character, but the result after sorting is:

-03A02
101
-101
102
-102
201
-201
202
-202
301
-301
302
-302
3A01
-3A01
3A02
T3A01

 

First, I felt that the sorting order was wrong, because the strings starting with a negative sign should be in the same order.

Then I found the following message on MSDN:

Use the word sorting rule to perform a region-sensitive comparison. In this comparison, special weights may be assigned to non-alphanumeric Unicode characters. Using the word sorting rules and conventions in a specific region, the weight of a hyphen ("-") may be very small, therefore, "coop" and "co-op" appear next to each other in the sorting list.

Then I basically understood that in C #, the "-" negative number permission is automatically downgraded because of the English language itself, resulting in such sorting problems.

Then I looked for the following solution:

In the List <T>. sort method, you can write the sorting method by yourself, or implement a class that inherits the IComparer interface. In the Compare implementation, you can write a string statement like this:

 

.Compare(x, y, StringComparison.Ordinal);

 

The third parameter is interpreted as "comparing strings using sequence number sorting rules"

"-" Will not be automatically downgraded.

Another possibility is that there is no such sort method for us to use. For example, in DataTable, I chose this method in DataTable:

  String2 : IComparable, IComparable<String2>  String2(=     (obj ==                 CompareTo(= obj  (other ==   

First, I declare a type that inherits IComparable and IComparable <String2> and implements the CompareTo method;

Then set the column type in the DataTable to String2, so the sorting is normal.

The above are the problems and solutions encountered in string sorting. I don't know if there is any better solution. I hope you can point out the error or be a rookie.
