![]() ![]() Return ret != null ? ret.DisplayName : pi. Var ret = pi.GetCustomAttributes(typeof(DisplayNameAttribute), true).Cast().SingleOrDefault() (Inherited from Attribute) Attribute. (Inherited from Attribute) Attribute.GetTypeInfo(UInt32, UInt32, IntPtr) Retrieves the type information for an object, which can be used to get the type information for an interface. Var pi = typeof(T).GetProperty(memberInfo.Name) Maps a set of names to a corresponding set of dispatch identifiers. The class with DisplayName1 Attribute: public class TestĪnd the extension method: public static string GetAttributeName(this T itm, Expression> propertyExpression) Test method: static void Main(string args)Ĭonsole.WriteLine(i.GetAttributeName(t => t.Name) + " " + i.GetAttributeName(t=>t.t2))) If DisplayNameAttribute is set the method will return it, otherwise it will return the MemberInfo name. For this reason, I prefer to make a ViewModel and decorate it with only the needed properties and display name attributes as required, then make a list of them.įollowing Rich Tebb's and Matt Baker's answer, I wanted to use the ReflectionExtensions methods in a LINQ query, but it didn't work, so I've made this method for it to work. However it will also filter out any of your own virtual properties if you choose to extend such classes. Useful if you are using model classes directly as EF puts in "Navigation" properties as virtual. The commented //Where clause will filter out virtual properties. If there's a more efficient / safer way of doing this, I'd appreicate any feedback. Object values = new object įor (int col = 0 col < Props.Length col++) IsDisplayNameAttributeDefined = Attribute.IsDefined(prop, typeof(DisplayNameAttribute)) ĭisplayNameAttribute dna = (DisplayNameAttribute)Attribute.GetCustomAttribute(prop, typeof(DisplayNameAttribute)) ĭataTable dataTable = new DataTable(typeof(T).Name) .Where(p => !p.GetGetMethod().IsVirtual & !p.GetGetMethod().IsFinal).ToArray() //Hides virtual propertiesīool isDisplayNameAttributeDefined = false PropertyInfo Props = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance) var model.AccountId shell.getParameter ('AccountId') var model.AllocatedManagedMemory shell.getParameter ('AllocatedManagedMemory') The shell.GetParameter get the value from a POST. public DataTable BuildDataTable(IList data) I need to set the properties with a foreach loop to add the values to my Model: This is how get values from POST the application. Just like in standard MVC, if you dont have DisplayName attribute defined, it will fall back to the property name so you only have to include DisplayName where it is different to the property name. This simple article will help us to manage the display titles using resource files with multi language support in an Asp.Net MVC application. It also helps in localization of display attributes. I pass in a list of a given type (Assuming you have a supporting class) and it generates a datatable with the properties as column headers and the list items as data. By using resource file, it will be easier to change the display name instead changing the C class file. Usage would be: string displayName = ReflectionExtensions.GetPropertyDisplayName(i => i.SomeProperty) If (memberExpr != null & = MemberTypes.Property) MemberExpr = unaryExpr.Operand as MemberExpression If (unaryExpr != null & unaryExpr.NodeType = ExpressionType.Convert) UnaryExpression unaryExpr = propertyExpression as UnaryExpression MemberExpression memberExpr = propertyExpression as MemberExpression Public static MemberInfo GetPropertyInformation(Expression propertyExpression)ĭebug.Assert(propertyExpression != null, "propertyExpression != null") Var attr = memberInfo.GetAttribute(false) StringLength, It defines a maximum length. "No property reference expression was found.", Commonly used Validation Annotations DisplayName, It is used to define the text we want to display for the fields. ![]() Var memberInfo = GetPropertyInformation(propertyExpression.Body) Public static string GetPropertyDisplayName(Expression> propertyExpression) MyResources.resx, and add a resource for your field: Then reference the name of the field and the MyResources type in your DisplayAttribute. ![]() Var attribute = member.GetCustomAttributes(typeof(T), false).SingleOrDefault() You can set the ResourceType on the DisplayAttribute which can be used to localize your text. Public static T GetAttribute(this MemberInfo member, bool isRequired) To exportAnnotations.Try these utility methods of mine: using System.ComponentModel You can also set whether to use the display name as the author name in the XFDF whenever exporting the annotations, by passing the option useDisplayAuthor: true ![]()
