You just need to provide object reference   Please provide your class name in the  position   private static void data2          lt classname gt  c1   new  lt classname gt         c1  data1

You can use call method by like this   Foo Data2    public class Foo       private static Foo  Instance       private Foo                    public static Foo GetInstance                 if   Instance    null               Instance   new Foo            return  Instance             protected void Data1                    public static void Data2                 GetInstance   Data1

You ll need to create an instance of the class and invoke the method on it   public class Foo       public void Data1                    public static void Data2                  Foo foo   new Foo             foo Data1

Static method never allows a non-static method call directly    Reason  Static method belongs to its class only  and to nay object or any instance    So  whenever you try to access any non-static method from static method inside the same class  you will receive    An object reference is required for the non-static field  method or property    Solution  Just declare a reference like   public class  lt classname gt    static method        new  lt classname gt  non-static       non-static method

You can t call a non-static method without first creating an instance of its parent class   So from the static method  you would have to instantiate a new object     Vehicle myCar   new Vehicle          and then call the non-static method   myCar Drive

Apologized to post answer for very old thread but i believe my answer may help other   With the help of delegate the same thing can be achieved   public class MyClass       private static Action NonStaticDelegate       public void NonStaticMethod                 Console WriteLine  Non-Static                public static void CaptureDelegate                 MyClass temp   new MyClass            MyClass NonStaticDelegate   new Action temp NonStaticMethod              public static void RunNonStaticMethod                 if  MyClass NonStaticDelegate    null                           This will run the non-static method                  Note that you still needed to create an instance beforehand             MyClass NonStaticDelegate

You have to create an instance of that class within the static method and then call it   For example like this   public class MyClass      private void data1                private static void data2             MyClass c   new MyClass         c data1

Perhaps what you are looking for is the Singleton pattern   public class Singleton       private Singleton           public void DoWork                     do something               You can call this static method which calls the singleton instance method      public static void DoSomeWork                  Instance DoWork               public static Singleton Instance               get   return instance                private static Singleton instance   new Singleton        You still have to create an instance of the class but you ensure there is only one instance

Assuming that both data1   and data2   are in the same class  then another alternative is to make data1   static   private static void data1       private static void data2        data1
