示例1: typeof
string tree1 = "maple";
string tree2 = "oak";
System.Reflection.MethodInfo addMethod = typeof(Dictionary<int, string>).GetMethod("Add");
// Create two ElementInit objects that represent the
// two key-value pairs to add to the Dictionary.
System.Linq.Expressions.ElementInit elementInit1 =
System.Linq.Expressions.Expression.ElementInit(
addMethod,
System.Linq.Expressions.Expression.Constant(tree1.Length),
System.Linq.Expressions.Expression.Constant(tree1));
System.Linq.Expressions.ElementInit elementInit2 =
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<int, string>.
System.Linq.Expressions.NewExpression newDictionaryExpression =
System.Linq.Expressions.Expression.New(typeof(Dictionary<int, string>));
// Create a ListInitExpression that represents initializing
// a new Dictionary<> instance with two key-value pairs.
System.Linq.Expressions.ListInitExpression listInitExpression =
System.Linq.Expressions.Expression.ListInit(
newDictionaryExpression,
elementInit1,
elementInit2);
Console.WriteLine(listInitExpression.ToString());輸出：
new Dictionary`2() {Void Add(Int32, System.String)(5,"maple"),
Void Add(Int32, System.String)(3,"oak")}
