1、直接返回DataSet對(duì)象

　　特點(diǎn)：通常組件化的處理機(jī)制，不加任何修飾及處理；

　　優(yōu)點(diǎn)：代碼精減、易于處理，小數(shù)據(jù)量處理較快；

　　缺點(diǎn)：大數(shù)據(jù)量的傳遞處理慢，消耗網(wǎng)絡(luò)資源；

　　建議：當(dāng)應(yīng)用系統(tǒng)在內(nèi)網(wǎng)、專網(wǎng)（局域網(wǎng)）的應(yīng)用時(shí)，或外網(wǎng)（廣域網(wǎng)）且數(shù)據(jù)量在KB級(jí)時(shí)的應(yīng)用時(shí)，采用此種模式。

2、返回DataSet對(duì)象用Binary序列化后的字節(jié)數(shù)組?

　　特點(diǎn)：字節(jié)數(shù)組流的處理模式；

　　優(yōu)點(diǎn)：易于處理，可以中文內(nèi)容起到加密作用；

　　缺點(diǎn)：大數(shù)據(jù)量的傳遞處理慢，較消耗網(wǎng)絡(luò)資源；

　　建議：當(dāng)系統(tǒng)需要進(jìn)行較大數(shù)據(jù)交換時(shí)采用。

3、返回DataSetSurrogate對(duì)象用Binary序列化后的字節(jié)數(shù)組?

　　特點(diǎn)：微軟提供的開(kāi)源組件；

　　優(yōu)點(diǎn)：易于處理，可以中文內(nèi)容起到加密作用；

　　缺點(diǎn)：大數(shù)據(jù)量的傳遞處理慢，較消耗網(wǎng)絡(luò)資源；

　　建議：當(dāng)系統(tǒng)需要傳輸中文數(shù)據(jù)或需要加密時(shí)采用此種方式

4、返回DataSetSurrogate對(duì)象用Binary序列化并Zip壓縮后的字節(jié)數(shù)組

　　特點(diǎn)：對(duì)字節(jié)流數(shù)組進(jìn)行壓縮后傳遞；

　　優(yōu)點(diǎn)：當(dāng)數(shù)據(jù)量大時(shí)，性能提高效果明顯，壓縮比例大；

　　缺點(diǎn)：相比第三方組件，壓縮比例還有待提高；

　　建議：當(dāng)系統(tǒng)需要進(jìn)行大數(shù)據(jù)量網(wǎng)絡(luò)數(shù)據(jù)傳遞時(shí)，建議采用此種可靠、高效、免費(fèi)的方法。?

　　測(cè)試用例：SqlServer2000數(shù)據(jù)庫(kù)，數(shù)據(jù)量大小40000行，字段數(shù)１０個(gè)，結(jié)果如下：

?

? 使用方法	? 用時(shí)(秒）	? 數(shù)據(jù)量(Byte)	? 大小 百分比(%)
? 直接返回DataSet	? 12.625	? 19629414	? 100%
? 返回二進(jìn)制序列化后DataSet	? 9.712	? 12049645	? 61.38%
? 返回轉(zhuǎn)化DataSetSurrogate的DataSet 并且二進(jìn)制序列化后	? 7.943	? 5138990	? 26.18%
? 返回轉(zhuǎn)化DataSetSurrogate的DataSet 并且二進(jìn)制序列化后使用zip壓縮	? 7.619	? 978033	? 4.98%
