What type of method is String dgvValue(int cell) in the below code?
private void btnEdit_Click(object sender, EventArgs e) { if (dgvGuestList.SelectedRows.Count > 0) { String dgvValue(int cell) { return dgvGuestList.SelectedRows[0].Cells[cell].Value.ToString(); } editGuest editGuest = new editGuest(int.Parse(dgvValue(0)), dgvValue(1), int.Parse(dgvValue(2)), dgvValue(0), dgvValue(0), dgvValue(0), dgvValue(0)); editGuest.ShowDialog(); } else { DialogResult error = MessageBox.Show("No row selected.", "Error", MessageBoxButtons.OK, MessageBoxIcon.Exclamation); } }

Similarly another method which is Method2() is being defined with 'public' access specifier and 'void' as return type and inside that Method2() the Method1() is called. Hence, this program shows that a method can be called within another method as both of them belong to the same class.
Recursion is a method that call itself. In this case it is a recursion.
Call a Method Inside main , call the myMethod() method: public class Main { static void myMethod() { System.out.println("I just got executed!"); } public static void main(String[] args) { myMethod(); } } // Outputs "I just got executed!"
You can't. Variables defined inside a method are local to that method. If you want to share variables between methods, then you'll need to specify them as member variables of the class. Alternatively, you can pass them from one method to another as arguments (this isn't always applicable).
It's a feature of c# called local functions, introduced in c# 7:
Many designs for classes include methods that are called from only one location. These additional private methods keep each method small and focused.
Local functions enable you to declare methods inside the context of another method. Local functions make it easier for readers of the class to see that the local method is only called from the context in which it is declared.
