The Increment() methods reduce the value of a given key if the corresponding value can be parsed to an integer value. These operations are provided at a protocol level to eliminate the need to get, update, and reset a simple integer value in the database. All the .NET Client Library methods support the use of an explicit offset value that will be used to reduce the stored value in the database. Note that the Increment methods may not be used with keys that were first created with a Store method. To initialize a counter, you must first use either Increment or Increment with a default value.

Increment the inventory counter by 1, defaulting to 100 if the key doesn't exist.

client.Remove("inventory"); //reset the counter
client.Increment("inventory", 100, 1); //counter will be 100
client.Increment("inventory", 100, 1); //counter will be 101

Increment the inventory counter by 1, defaulting to 100 if the key doesn't exist and set an expiry of 60 seconds.

client.Increment("inventory", 100, 1, TimeSpan.FromSeconds(60));

Increment the inventory counter by 1, defaulting to 100 if the key doesn't exist and set an expiry of 5 minutes.

client.Increment("inventory", 100, 1, DateTime.Now.AddMinutes(5));

Increment the inventory counter by 1, defaulting to 100 if the key doesn't exist. Fail if CAS value doesn't match CAS value on server.

var result = client.ExecuteGet("inventory");
client.Increment("inventory", 100, 1, result.Cas);

Increment the inventory counter by 1, defaulting to 100 if the key doesn't exist and set an expiry of 60 seconds. Fail if CAS value doesn't match CAS value on server.

var result = client.ExecuteGet("inventory");
client.Increment("inventory", 100, 1, TimeSpan.FromSeconds(60), result.Cas);

Increment the inventory counter by 1, defaulting to 100 if the key doesn't exist and set an expiry of 5 minutes. Fail if CAS value doesn't match CAS value on server.

var result = client.ExecuteGet("inventory");
client.Increment("inventory", 100, 1, DateTime.Now.AddMinutes(5), result.Cas);

ExecuteIncrement will return an instance of an IMutateOperationResult
