C # Remove extra spaces in the string attributes of the class from reflection

Today, meow encountered a problem.

Some string fields in the database I designed are fixed-length strings. The entity values are extracted from the string with extra spaces.

So I want to remove the extra spaces.

I wrote a method to remove extra spaces in the string attribute of the entity and used reflection.

This removes unnecessary spaces.

 

Code:

1. /// <Summary>
2. /// Remove unnecessary spaces in the string attribute of the class
3. /// </Summary>
4. /// <Param name = "OBJ"> </param>
5. /// <Returns> </returns>
6. Public static object trimstr (Object OBJ)
7. {
8. Type T = obj. GetType ();
9. // Attribute array
10. Propertyinfo [] properties = T. getproperties ();
12. // Traverses the attribute array
13. Foreach (propertyinfo P in properties)
14. {
15. If (P. propertytype. Name = "string") // string attribute
16. {
17. // Obtain the value
18. String STR = (string) p. getvalue (OBJ, null );
19. // Assign a value again
20. P. setvalue (OBJ, str. Trim (), null );
21. }
22. }
24. Return OBJ;
25. }
