监听布尔值以在循环中更改，然后仅调用一次方法

Question

Is there any way to listen for a bool-value change then cal a method only once?

I'm working on project where I need to constantly monitor a variable that's a bool, and depending on if it's a TRUE or FALSE call a diffrent method.

I'm currently using an if-statment, which calls each method on loop when my variable is TRUE/FALSE.

Any help would be much appreciated.

Answer 1

You can use bool property

private bool boolValue;
public bool BoolValue
{
 get { return boolValue; }
 set { 
     boolValue = value;
     if(value) { TrueMethod(); } 
     else { FalseMethod(); }

     }
}

I would use the PropertyChanged event to have loosly coupling.
