Question

我有一个Radgrid控制列表屏幕。默认的页面大小是30。当我将页面大小更改为30000时，wcf将成功返回记录。但是当我再次请求相同的页面大小数据时，它会显示错误消息：-

服务器未提供有意义的回复；这可能是由于合同不匹配，会话过早关闭或服务器内部错误引起的。

Additional Info: An error has occurred while retrieving grid data.

请注意，数据传输的大小已设置为最大限制：

<httpsTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" />

那么为什么它在第一次但第二次不起作用？

WCF返回服务器未提供有意义的答复。这可能是由于合同不匹配造成的
