.net 未能分配134217728字节的托管内存缓冲区。可用内存量可能较低

我试图通过WCF服务调用将大量数据保存到数据库中。我无法调用该服务。这是一个错误

codeProxy.SaveCodes(requestHeader, codes, Rawcodes);

未能分配134217728字节的托管内存缓冲区。这个 可用内存量可能较低

我已将服务器端和客户端的web配置配置为最大限制

使用WCF操作的消息契约中的流属性来传输大型对象

[MessageContract]
public class DocumentDescription
{
    [MessageBodyMember(Namespace = "http://example.com/App")]
    public Stream Stream { get; set; }
}

以这种方式配置绑定

<binding name="Binding_DocumentService" receiveTimeout="03:00:00"
        sendTimeout="02:00:00" transferMode="Streamed" maxReceivedMessageSize="2000000">
    <security mode="Transport" />
</binding>

要将大数据上载到SQL Server数据库，请使用以下文章中描述的方法

如果在.Net 2.0服务中遇到此问题，此修补程序可能会有所帮助

问题 运行基于.NET Framework 2.0的应用程序时 应用程序崩溃。如果调试应用程序，您会注意到 引发System.InsufficientMemoryException异常。那么，你 接收类似以下内容的错误消息：未能 分配字节的托管内存缓冲区。可用的数量 内存可能不足

原因 问题1的起因

当应用程序尝试运行时，此问题会间歇性出现 为大型对象堆（LOH）中的大型对象分配内存。这个 当以下条件为真时，将触发错误消息： 堆无法提供足够的内存来满足LOH分配 要求同时正在进行并发垃圾回收 时间问题2的起因

出现此问题的原因是，垃圾收集器的堆平衡非常小 对象分配不会在具有 超过8个逻辑处理器。正因为如此，更多的垃圾 当出现异常时，会触发集合以保持堆平衡 不同处理器中的工作负载不平衡。因此, 应用程序在垃圾收集上花费更多的时间

那么你想发送多少数据呢？我们正在使用wshttpbinding将一组50K记录从表示层传递到WCF服务。
