示例1: Dictionary
Dim tree1 As String = "maple"
Dim tree2 As String = "oak"
Dim addMethod As System.Reflection.MethodInfo = _
Type.GetType("System.Collections.Generic.Dictionary`2[System.Int32, System.String]").GetMethod("Add")
' Create two ElementInit objects that represent the
' two key-value pairs to add to the Dictionary.
Dim elementInit1 As System.Linq.Expressions.ElementInit = _
System.Linq.Expressions.Expression.ElementInit( _
addMethod, _
System.Linq.Expressions.Expression.Constant(tree1.Length), _
System.Linq.Expressions.Expression.Constant(tree1))
Dim elementInit2 As System.Linq.Expressions.ElementInit = _
System.Linq.Expressions.Expression.ElementInit( _
addMethod, _
System.Linq.Expressions.Expression.Constant(tree2.Length), _
System.Linq.Expressions.Expression.Constant(tree2))
' Create a NewExpression that represents constructing
' a new instance of Dictionary(Of Integer, String).
Dim newDictionaryExpression As System.Linq.Expressions.NewExpression = _
System.Linq.Expressions.Expression.[New](Type.GetType("System.Collections.Generic.Dictionary`2[System.Int32, System.String]"))
' Create a ListInitExpression that represents initializing
' a new Dictionary(Of T) instance with two key-value pairs.
Dim listInitExpression As System.Linq.Expressions.ListInitExpression = _
System.Linq.Expressions.Expression.ListInit( _
newDictionaryExpression, _
elementInit1, _
elementInit2)
Console.WriteLine(listInitExpression.ToString())输出：
new Dictionary`2() {Void Add(Int32, System.String)(5,"maple"),
Void Add(Int32, System.String)(3,"oak")
