C# Passing a method as a parameter to another method [duplicate]

Answer 1

You can use the Action delegate type.

public void ErrorDBConcurrency(DBConcurrencyException e, Action method)
{
    if (MessageBox.Show("You must refresh the datasource") == DialogResult.OK)
        method();
}

Then you can use it like this:

void MyAction()
{

}

ErrorDBConcurrency(e, MyAction); 

If you do need parameters you can use a lambda expression.

ErrorDBConcurrency(e, () => MyAction(1, 2, "Test"));
