[c#] How do I call a non-static method from a static method in C#?

I have the following code, I want to call data1() from data2(). Is this possible in C#? If so, how?

private void data1()
{
}
private static void data2()
{
   data1(); //generates error
}

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();

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 <classname>
{
static method()
{
   new <classname>.non-static();
}

non-static method()
{

}


}

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();
   }
}

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'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();
    }
}

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 just need to provide object reference . Please provide your class name in the position.

private static void data2()
{
    <classname> c1 = new <classname>();
    c1. data1();
}

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();
}

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.
