c# - A method that returns string value -

i trying create method(that makes labels slide left). i've tried , researched bit , came this.

public static void slidingtext(string a) {     string first = a.substring(1, a.length - 1);     string second= a.substring(0, 1);     = first + second;     return a; } 

however, when use this(on button etc) :

slidingtext(label1.text); 

i nothing. have worked on while , saw can text value of label1 , change in method changed value never goes out of method. missing , still couldn't figure out missing.

regards

there 2 ways of making work:

• change code take string a reference, or
• change code return string.

here first solution (this not work properties):

public static void slidingtext(ref string a)     {         string first = a.substring(1, a.length - 1);         string second= a.substring(0, 1);         = first + second;     } 

here second solution:

public static string slidingtext(string a)     {         string first = a.substring(1, a.length - 1);         string second= a.substring(0, 1);         return first + second;     } 

this require assignment on caller's side.

you can further optimize code make single line of code:

public static string slidingtext(string a) {     return a.substring(1) + a[0]; }
