示例1: typeof
// Add the following directive to your file:
// using System.Linq.Expressions;
// A label expression of the void type that is the target for the GotoExpression.
LabelTarget returnTarget = Expression.Label();
// This block contains a GotoExpression.
// It transfers execution to a label expression that is initialized with the same LabelTarget as the GotoExpression.
// The types of the GotoExpression, label expression, and LabelTarget must match.
BlockExpression blockExpr =
Expression.Block(
Expression.Call(typeof(Console).GetMethod("WriteLine", new Type[] { typeof(string) }), Expression.Constant("GoTo")),
Expression.Goto(returnTarget),
Expression.Call(typeof(Console).GetMethod("WriteLine", new Type[] { typeof(string) }), Expression.Constant("Other Work")),
Expression.Label(returnTarget)
);
// The following statement first creates an expression tree,
// then compiles it, and then runs it.
Expression.Lambda<Action>(blockExpr).Compile()();输出：
GoTo "Other Work" is not printed because the GoTo expression transfers execution from Expression.GoTo(returnTarget) to Expression.Label(returnTarget).
