为什么要先创建一个委托？

如何解决为什么要先创建一个委托？

在循环中，为什​​么创建一个动作然后调用它？它会获得更好的性能吗？直接运行代码怎么样？

foreach (FieldInfo TargetMember in targettype.GetFields(BindingFlags.Public | BindingFlags.Instance)) {
    Action work = delegate {
        for (int Ordinal = 0; Ordinal < RecordInstance.FieldCount; OrdinaL++) {
            //Check if the RecordFieldName matches the TargetMember
            if (MemberMatchesName(TargetMember,RecordInstance.GetName(Ordinal))) {
                Expression TargetValueExpression = GetTargetValueExpression(
                                                        RecordInstance,Culture,recordInstanceExp,SchemaTable,Ordinal,TargetMember.FieldType);

                //Create a binding to the target member
                MemberAssignment BindExpression = Expression.Bind(TargetMember,TargetValueExpression);
                Bindings.Add(Ordinal,BindExpression);
                return;
            }
        }
    };
    work();
}
