Assembly:  Microsoft.ServiceBus (in Microsoft.ServiceBus.dll)

public IDictionary<string, Object> Parameters { get; }

Property Value

Type: System.Collections.Generic.IDictionary<String, Object>
The value of a rule action.

You can use the Parameters property to define a parameterized expression that indirectly sets the value of a rule action, rather than specifying the value as part of the filter expression itself. This is very similar to parameterized SQL.

A benefit to using parameterized filter expressions is that you do not have to escape the string as part of the filter expression grammar. This makes it easier, for example, to construct the filter expression based on user input. Additionally, the parameter enables you to use constant literals that are not part of the grammar, such as DateTime, DateTimeOffset, TimeSpan, Guid, and so on, since they can now appear directly as part of the Parameters property.

A valid parameter name always starts with the @ symbol, and the first character must be any Unicode character that is categorized as a Unicode letter. The second and subsequent characters can be any Unicode character that is categorized as a Unicode letter or a Unicode digit.
