A small knowledge in C #

This is my first blog post. I will not talk much about nonsense. Let's go straight to the topic. I am a newbie. As a newbie, I look at the variable. Tostring ()... why can it be ??? So I took some frameworks from my previous project and looked at them. The following example is provided:

Public static partial class OVerrid
{
Public static int ToInt (this object value, int def)
{
If (value = null)
{
Return def;
}
Int result;
If (! Int. TryParse (value. ToString (), out result ))
{
Return def;
}
Return result;
}

Public static int ToInt (this object value)
{
Return ToInt (value, 0 );
}
}

 

Static void Main (string [] args)
{
String aa = "";
Aa. ToInt ();

}

 

Is it naive ?? No way !! Continue Learning and exploring!
