ElementInit Class
Visual Studio 2010
Represents an initializer for a single element of an IEnumerable collection.
Assembly: System.Core (in System.Core.dll)
The ElementInit type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() | AddMethod | Gets the instance method that is used to add an element to an IEnumerable collection. |
![]() ![]() | Arguments | Gets the collection of arguments that are passed to a method that adds an element to an IEnumerable collection. |
| Name | Description | |
|---|---|---|
![]() ![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() ![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() ![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() ![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() ![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | ToString | Returns a textual representation of an ElementInit object. (Overrides Object.ToString.) |
![]() | Update | Creates a new expression that is like this one, but using the supplied children. If all of the children are the same, it will return this expression. |
The following example creates an ElementInit that represents the initialization of an element of a dictionary collection.
Dim tree As String = "maple" Dim addMethod As System.Reflection.MethodInfo = _ Type.GetType("System.Collections.Generic.Dictionary`2[System.Int32, System.String]").GetMethod("Add") ' Create an ElementInit that represents calling ' Dictionary(Of Integer, String).Add(tree.Length, tree). Dim elementInit As System.Linq.Expressions.ElementInit = _ System.Linq.Expressions.Expression.ElementInit( _ addMethod, _ System.Linq.Expressions.Expression.Constant(tree.Length), _ System.Linq.Expressions.Expression.Constant(tree)) Console.WriteLine(elementInit.ToString()) ' This code produces the following output: ' ' Void Add(Int32, System.String)(5,"maple")
