C# extension method for object change type
##About
Strong type is good, but sick.
Weak type is sick, but good.
This lib provides a shortcut to use System.Convert.ToXXX() and the other misc like reflection.
It will throw exception by default, because you should know what are you doing.
You can pass false to throwEx param and get the target type default value.
##Example
Using QuickConvert;
string s1 = "123";
int i1 = s1.ToInt(); // i1 = 123
string s2 = "abc";
int i2 = s2.ToInt(); // Exception
int i2 = s2.ToInt(false); // i2 = 0;
