public string FoundObjectMessagesSeparator { get; set; }

Property Value

Type Description

A string value that represents a separator.


Set this property if the RuleUniqueValueAttribute.FoundObjectMessageFormat property is not set to an empty string (by default, it is set to “{0}”). When several objects with the same property value as the target property are found, they should be separated by a symbol when being added to the error message of this rule. By default, this property is set to “, “.


When defining the RuleUniqueValueAttribute in code, the value for the FoundObjectMessageSeparator property is passed as a named parameter. This means that you do not have to specify it. However, when specifying, use the following format: FoundObjectMessageSeparator = “; “ (FoundObjectMessageSeparator := “; “, in Visual Basic).
