发送一个Hashtable到Webservice [英] Sending a Hashtable to a Webservice

问题描述

我试图发送具有通用键和值类型的项目列表到asp.net webservice。
我该怎么做？
我尝试使用列表<字典< String，String>> ，但这不工作。我没有得到例外，但是当我在webserivice中断时，我的集合是空的。
数据可能如下所示：
{Data：{fieldtype：integer，isrequired：true，isrequirederror：无效数据}
但是正如我所说，键是通用的，有时候还有更多的属性，有时不是。

Im trying to send a List of Items with generic Keys and Value Types to a asp.net webservice. How can i do this? I tried it with List<Dictionary<String, String>>, but this doens't work. I do not get an exception, but when i break in the webserivice, my collection is null. The Data could look like this: {"Data":{"fieldtype":"integer","isrequired":true,"isrequirederror":"Invalid Data"}}. But as i said, the Keys are generic, sometimes there are more properties, sometimes not.

Thx alot

推荐答案

p>如果您要在服务中引入任何类型的泛型，从SOA和WCF的困难时期开始，从序列化/反序列化问题开始，并完成互操作性问题。

You are going to have hard times with SOA and WCF in particular if you want to introduce any kind of generics in your service - starting from serialization/deserialization issues and finishing interoperability issues.

不要使用通用参数。由于读/写操作性能，哈希表（或词典）仅在进程内使用中才有意义。如果你想通过电线传输这样一种格式的东西，可以使用如下结构：
对（/ string）串的列表

Don't use generic parameters. Hashtable (or Dictionary) makes sense only within in-process usage due to read/write operations performance. If you want to transmit something in such format over the wire, use something like the following structure: List of pairs (string, string).
