远程方法调用期间出现 OutOfMemoryException
我在进行远程方法调用时收到 OutOfMemoryException。
“RemoteEntity.SetLocalStore（数据集）；”
传递的值是数据集。
注意数据集大小为 38mb

感谢
代码：
private void backgroundSync_DoWork(object sender, DoWorkEventArgs e)
{
backgroundSync.ReportProgress(10, "Fetching data for sync ...");
EngagementSet _remoteSet = HKMPClient.Instance.RemoteEntity.GetLocalStore();
//Update to release memory.
HKMPClient.Instance.RemoteEntity.SetLocalStore(null);
//dispose RemoteEntity
HKMPClient.Instance.DisconnectAndDispose();
HKMP.EngagementWorks.Windows.BLL.Engagements.Engagement.MergeEntitiesInLimitedConnecitivity(_remoteSet,EngagementID);
backgroundSync.ReportProgress(10, "Synchronizing Engagement ...");
DialogSync _dlgSync = new DialogSync(this.EngagementID, _remoteSet);
_dlgSync.ServiceRequestStarted += new DialogSync.OnServiceRequestStarted(_dlgSync_ServiceRequestStarted);
_dlgSync.ServiceRequestCompleted += new DialogSync.OnServiceRequestCompleted(_dlgSync_ServiceRequestCompleted);
if (_dlgSync.IsShown())
{
_dlgSync.StartPosition = FormStartPosition.CenterParent;
_dlgSync.WindowState = FormWindowState.Normal;
_dlgSync.ShowDialog();
}
//Disposed to release object.
_dlgSync.Dispose();
_dlgSync = null;
// connect again
HKMPClient.Instance.Connect(e.Argument.ToString());
_remoteSet.RemotingFormat = SerializationFormat.Binary;
HKMPClient.Instance.RemoteEntity.SetLocalStore(_remoteSet);
}
Iam getting OutOfMemoryException while making remote method call.
"RemoteEntity.SetLocalStore(DATASET);"
passed value is dataset.
Note Size of dataset is 38mb

我想你知道答案，38mb 对于远程调用来说太大了。有助于进一步诊断的方法是通过将问题简化为仅在本地运行的两个函数来显示完整的示例。
这将有助于检测它是否是数据集的大小或远程接口/网络配置中的大小限制。
此外，拥有一个工作示例将允许其他人复制问题并查看类型信息（例如，我们看不到抛出异常的对象类型，也无法在 MSDN 中查找任何约束）。我相信有人能够提供明确的答案。
将代码简化为示例的行为本身可能会让您找到原因。

I think you know the answer, 38mb is WAY too big to do over a remote call. What will help diagnose it further would be to show a complete example by simplfying your problem to just two functions running locally.
This will help detect if it is the size of the dataset or a size constraint in the remote interface / network configuration.
Additionally having a working sample would allow someone else to replicate the issue and see the type information (for example, we can't see what object type is throwing the exception and can't look up any constraints in MSDN). I'm sure with this someone would be able to provide a definitive answer.
The act of reducing your code to a sample will in itself probably enable you to find the cause.
