1、直接返回DataSet对象
特点：通常组件化的处理机制，不加任何修饰及处理；
优点：代码精减、易于处理，小数据量处理较快；
缺点：大数据量的传递处理慢，消耗网络资源；
建议：当应用系统在内网、专网（局域网）的应用时，或外网（广域网）且数据量在KB级时的应用时，采用此种模式。
2、返回DataSet对象用Binary序列化后的字节数组
特点：字节数组流的处理模式；
优点：易于处理，可以中文内容起到加密作用；
缺点：大数据量的传递处理慢，较消耗网络资源；
建议：当系统需要进行较大数据交换时采用。
3、返回DataSetSurrogate对象用Binary序列化后的字节数组
特点：微软提供的开源组件；
优点：易于处理，可以中文内容起到加密作用；
缺点：大数据量的传递处理慢，较消耗网络资源；
建议：当系统需要传输中文数据或需要加密时采用此种方式
4、返回DataSetSurrogate对象用Binary序列化并Zip压缩后的字节数组
特点：对字节流数组进行压缩后传递；
优点：当数据量大时，性能提高效果明显，压缩比例大；
缺点：相比第三方组件，压缩比例还有待提高；
建议：当系统需要进行大数据量网络数据传递时，建议采用此种可靠、高效、免费的方法。
测试用例：SqlServer2000数据库，数据量大小40000行，字段数１０个，结果如下：
