i have custom class contains string. program has array of these classes , want able compare 1 array of these another.

i have implemented icomparable interface described here: http://www.informit.com/articles/article.aspx?p=25352&seqnum=4 find not allow me compare 1 array against another. (it allows me sort array)

public class myclass : icomparable<myclass>     {         #region private         private string _name;         #endregion          #region public          [xmlelement("name")]         public string name         {             get{return _name;}             set{_name= value;}         }         #endregion          public int compareto(myclass class)         {             string s1 = this.name;             string s2 = class.name;             return string.compare(s1, s2);         }          override public string tostring()         {             return _name;         }     } 

my program has array of these classes so:

myclass class1 = new myclass(); class1.name = "a";  myclass class2 = new myclass(); class2.name = "b";  myclass class3 = new myclass(); class3.name = "c";  myclass class4 = new myclass(); class4.name = "d";  myclass[] classes1 = { class1, class2, class3} myclass[] classes2 = { class1, class2, class4}; 

i can sort class if need be:

array.sort(classes2); 

what interface need implement allow me compare 1 array against see if equal?

edit class custom , not inherit interfaces want know interface implement, how implement , how use it. example uses objects not custom: easiest way compare arrays in c#

your class needs override equals method.
alternatively, can implement iequatable interface.
can apply "sequenceequals" linq operator arrays in order achieve desire.
