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));

Console.WriteLine(elementInit.ToString());

// This code produces the following output:
//
// Void Add(Int32, System.String)(5,"maple")
