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 the Object 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.
string tree = "maple"; System.Reflection.MethodInfo addMethod = typeof(Dictionary<int, string>).GetMethod("Add"); // Create an ElementInit that represents calling // Dictionary<int, string>.Add(tree.Length, tree). System.Linq.Expressions.ElementInit elementInit = System.Linq.Expressions.Expression.ElementInit( addMethod, System.Linq.Expressions.Expression.Constant(tree.Length), System.Linq.Expressions.Expression.Constant(tree)); outputBlock.Text += elementInit.ToString() + "\n"; // This code produces the following output: // // Void Add(Int32, System.String)(5,"maple")
