关于wcf返回二维数组的问题

[haroun]

我用wcf返回二维数组，经测试在超过1500行数据时，就会抛出“基础连接已经关闭: 连接被意外关闭”的异常信息。经测试该返回值长度22M左右，但是我用DataSet作为结果返回到33M都没有问题。请问有谁知道其中的原因吗？我的配置文件是：

建议你超过1m的传输量时用streamed模式

另外数组的index是int型的，是否超过了int的maxvalue？你22m有多少个项了呢？然后你把buffersize也设置的大些，看你没有设置，默认只有65536.
还有recievetimeout也要加大，22m，如果用http来连接，估计10分钟不够。
