Calling functions in another form.

Question

form1: public static void Method1() { Method2(); } private void Method2() { } form2: form1.Method1(); Calling Method2() gives: Error 1 An object reference is required for the non-static field, method, or property

Sam Hobbs · Answer

The fundamental problem is that Method1 is static and Method2 is not.

Frogleg · Answer

Look at this namespace StaticMethod { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load( object sender, EventArgs e) { } public static void Method1() { Form1 Fm1Instance = new Form1 (); // need instance Fm1Instance.Method2(); } private void Method2() { MessageBox .Show( "Method2" ); } public static void Method3() { Method4(); // can call static } public static void Method4() { MessageBox .Show( "Method4" ); } private void bttnShowForm2_Click( object sender, EventArgs e) { Form2 fm2 = new Form2 (); fm2.Show(); } private void bttnmethod1_Click( object sender, EventArgs e) { Method1(); } private void bttnMethod4_Click( object sender, EventArgs e) { Method3(); } } } Form2------------- namespace StaticMethod { public partial class Form2 : Form { public Form2() { InitializeComponent(); } private void Form2_Load( object sender, EventArgs e) { } private void bttnMethod1_Click( object sender, EventArgs e) { Form1 .Method1(); } } }
