- viewContext
- ViewContext
A ViewContext instance for the current scope.
- modelExplorer
- ModelExplorer
ModelExplorer for the expression. If null, calculates the
expression result using Eval(String).
- expression
- String
Expression name, relative to the current model.
- allowMultiple
- Boolean
If true, require a collection expression result. Otherwise, treat result as a
single value.
Returns
null if no expression result is found. Otherwise a
ICollection<T> containing current values for the given
expression.
Converts the expression result to a String. If that result is an
IEnumerable type, instead converts each item in the collection and returns
them separately.
If the expression result or the element type is an Enum, returns a
String containing the integer representation of the Enum value as well
as all Enum names for that value. Otherwise returns the default String
conversion of the value.
