The role of the static keyword in C #

There are two types of static allocations:
1. Used in the class of properties, methods, such static properties and methods do not need to create an instance can be accessed, through the class name or object names can access it, static properties, methods only "one copy": That is, if a class has a new n objects, the n objects only the same static property  and method;
2. Static variables inside the method:
  Static variables inside the method, the execution of the static variable value does not disappear, the method of executing this object again, the value still exists, it is not allocated in the stack, is in the static zone analysis, which is the largest difference with local variables;
