Using another class in WPF C# Project -

how make object of class in mainclass.

namespace wpfapplication1 {     public partial class mainwindow : window     {           public mainwindow()         {              initializecomponent();          }          myclass obj = new myclass();         //obj.show(); //not possible!!       }      public partial class myclass     {         void show()         {          }     }  } 

now in project, can't access show() method using "obj" object. how access method of class in project??

you must declare show public void have access method.

namespace wpfapplication1 {     public partial class mainwindow : window     {           public mainwindow()         {              initializecomponent();             obj.show(); //and must inside of method, function or constructor.          }          myclass obj = new myclass();         //obj.show(); //not possible beacause not public method.!!       }      public partial class myclass     {         //public method.         public void show()         {          }     }  }
