Decrement Method

SharedData Decrement Method

C# API

Decrements an integer value associated with the specified key in the Shared Data Server.

Namespace: Facilita.Fc.Runtime
Assembly: fc_clr (in fc_clr.dll) Version: 9.5.5.77

Syntax

public int Decrement(
	string key,
	int inc
)

public int Decrement(
	string key,
	int inc
)

Parameters

key: Type: System String
The key against which the value to be decremented is stored.

inc: Type: System Int32
The amount by which to decrement.

Return Value

The new, decremented value.

Remarks

The specified key must already be associated with a value, which can be set by calling Set(String, String) or SetInt(String, Int32). If the value associated with key is not a decrementable value then no action takes place.

A negative decrement value can be supplied.

Note
The keys are case-sensitive.
