BusinessObjectBase..::..GetPropertyNameCore Method
Resolves the property name from a property-reference expression, supporting both direct
member access and value-type-conversion wrappers. This is the underlying worker used by
[GetPropertyName{TObject}(Expression{Func{TObject, object}})]; derived classes
can call it directly when working with an already-built Expression tree.
Namespace:
AdvantageCMS.Core.Admin.BaseClassesAssembly: AdvantageCMS.Core (in AdvantageCMS.Core.dll)
Syntax
protected static string GetPropertyNameCore( Expression propertyRefExpr )
Parameters
- propertyRefExpr
- Type: Expression
The expression body to inspect — typically a MemberExpression, or a UnaryExpression wrapping one for value-typed properties.
Return Value
The property's name as a string.Exceptions
| Exception | Condition |
|---|---|
| ArgumentNullException | propertyRefExpr is null. |
| ArgumentException | No property reference expression was found in propertyRefExpr. |
Examples
C#
// Typically called via GetPropertyName, but can be invoked directly with a raw Expression body: Expression<Func<AgentConfig, object>> expr = p => p.Name; string propName = GetPropertyNameCore(expr.Body); // propName == "Name" // Value-typed property — the Expression body is a UnaryExpression (Convert) that // GetPropertyNameCore unwraps automatically: Expression<Func<AgentConfig, object>> verExpr = p => p.Version; string verProp = GetPropertyNameCore(verExpr.Body); // verProp == "Version"
