无法通过 nettcp 绑定和 transfermode="buffered" 上传大文件

Question

我有一个应用程序，我在其中一种方法中将文件传输到服务器。

我可以轻松上传大约 50 KB 的文件。但我的最大限制约为 3 MB。

我的 WCR 服务通过 nettcpbinding 托管在 Windows 服务中

我的windows配置是

<configuration>  
  <system.serviceModel>
    <services>
      <service name="BTWAServerWindowsService.BatchManagementService"
               behaviorConfiguration ="BatchManagementService">
        <host>
          <baseAddresses>
            <add baseAddress="net.tcp://localhost:9999/BatchManagementService" />
          </baseAddresses>
        </host>
        <endpoint name="BatchManagementServiceEndPoint"
        address =""
        binding="netTcpBinding"
        contract="BTWAServerWindowsService.IBatchManagementService">
        </endpoint>
        <endpoint name="BatchManagementServiceMetadataPoint" address="mex"
                binding="mexTcpBinding"
                contract="IMetadataExchange"/>
      </service>      
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="BatchManagementService">
          <serviceMetadata httpGetEnabled="False"/>
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>       
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

我的客户端配置是

<configuration> 
  <system.serviceModel>
    <bindings>
      <netTcpBinding>
        <binding name="BatchManagementServiceEndPoint" closeTimeout="00:10:00"
          openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"
          transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions"
          hostNameComparisonMode="StrongWildcard" listenBacklog="524288"
          maxBufferPoolSize="524288" maxBufferSize="524288" maxConnections="524288"
          maxReceivedMessageSize="524288">
          <readerQuotas maxDepth="524288" maxStringContentLength="524288"
            maxArrayLength="524288" maxBytesPerRead="524288" maxNameTableCharCount="524288" />
          <reliableSession ordered="true" inactivityTimeout="00:10:00"
            enabled="false" />
          <security mode="Transport">
            <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />
            <message clientCredentialType="Windows" />
          </security>
        </binding>       
      </netTcpBinding>
    </bindings>
    <client>
      <endpoint address="net.tcp://localhost:9999/BatchManagementService"
        binding="netTcpBinding" bindingConfiguration="BatchManagementServiceEndPoint"
        contract="BTWABatchManagement.IBatchManagementService" name="BatchManagementServiceEndPoint" />      
    </client>
  </system.serviceModel>
</configuration>

目前我无法将传输模式更改为流式传输，因为还有许多其他方法

请建议我将文件限制增加到 4 mb 所需的配置更改

在服务端 app.config 和客户端 app.config 中的 netTcpBinding 中更改以下属性

maxBufferPoolSize="1073741824" maxBufferSize="1073741824" maxConnections="10"
          maxReceivedMessageSize="1073741824">
          <readerQuotas maxDepth="32" maxStringContentLength="2147483647"
            maxArrayLength="2147483647" maxBytesPerRead="4096" maxNameTableCharCount="16384" />

这些属性的最大值是2147483647

<bindings>
      <netTcpBinding>
        <binding name="BatchManagementServiceEndPoint" closeTimeout="00:10:00"
          openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"
          transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions"
          hostNameComparisonMode="StrongWildcard" listenBacklog="524288"
          maxBufferPoolSize="1073741824" maxBufferSize="1073741824" maxConnections="10"
          maxReceivedMessageSize="1073741824">
          <readerQuotas maxDepth="32" maxStringContentLength="2147483647"
            maxArrayLength="2147483647" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
          <reliableSession ordered="true" inactivityTimeout="00:10:00"
            enabled="false" />
          <security mode="Transport">
            <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />
            <message clientCredentialType="Windows" />
          </security>
        </binding>       
      </netTcpBinding>
</bindings>

希望对你有帮助
