Use the increment () | decrement () Operation Summary of the memcached provider Client

Use the memcached provider client to perform the increment | decrement () operation:

1. During store, only int numbers of string type can be properly stored in increment and decrement; otherwise (increment \ decrement), return-1.

Failed:

 
This. Cache. Add ("Num1",100); // String should be input here.LongNewnum =This. Cache. increment ("Num1",1); // Failed, return-1
 

Successful:

 
This. Cache. Add ("Num1","100");LongNewnum =This. Cache. increment ("Num1",1); // Success, 101 is returned
 

 

2. In increment and decrement, if the key does not exist, the value is smaller than 0, and the value is not an integer,-1 is returned.

Increment and decrement are thread-safe.

 

3. In decrement, if the value is 0, the value is always 0 and will not decrease.
