I want to extract the guard statement from the following method
private void CreateProxy()
{
//extract the following guard statement.
Host selected = this.comboBox1.SelectedItem as Host;
if (selected == null)
{
return;
}
this.SearchProxy = ServiceProxy.ProxyFactory.CreateSearchProxy(GetSelectedIP().ToString());
this.StreamProxy = ServiceProxy.ProxyFactory.CreatePlayerProxy(GetSelectedIP().ToString());
}
//extracted guard method
public bool IsHostSelected()
{
Host selected = this.comboBox1.SelectedItem as Host;
if (selected == null)
{
return false;
}
return true;
}
see? now i have to add return value for the extracted method, is this kinda ugly?
any better solution to avoid adding the return value for the extracted method?
