Question

我尝试了很多但没有成功，

我已将我的WinForms以及WCF配置文件的readerQuotas maxStringContentLength更改为2147483647，但仍然将maxStringContentLength设置为8192 。

在WinForms或WCF服务上，任何正文都可以告诉我如何更改它以及在哪里进行更改。

Answer 1

您的客户端配置似乎没问题，修改了您的服务配置并将相应的行为添加到服务中，如下所示。

您需要正确设置绑定和行为。右键单击您的Web配置并选择编辑WCF配置。

enter image description here 例如，

 <bindings>
      <basicHttpBinding>
        <binding name="defaultBinding">
          <readerQuotas maxStringContentLength="1048576" />
        </binding>
      </basicHttpBinding>
    </bindings>
    <services>
      <service name="Service1">
        <endpoint address="http://localhost:56529/Service1.svc" 
  binding="basicHttpBinding" bindingConfiguration="defaultBinding" 
  contract="IWebExtractServiceIWebExtractService">
        </endpoint>
      </service>
    </services>

Answer 2

您已在服务的Web配置中定义了绑定配置，但您从未告诉服务使用它，因此使用了basicHttpBinding的默认值。

在WCF 4.0+中，你有两种方法可以做到这一点（Sajeethran给出了一个）。

您可以通过省略绑定配置上的name属性来定义绑定的配置并将其设置为服务的默认配置，如下所示：

<system.serviceModel>
<bindings>
  <basicHttpBinding>
    <binding closeTimeout="00:01:00" openTimeout="00:01:00" 
             receiveTimeout="00:10:00" sendTimeout="00:01:00"
             allowCookies="false" bypassProxyOnLocal="false"
             hostNameComparisonMode="StrongWildcard"
             maxBufferSize="2147483647" maxBufferPoolSize="2147483647"
             maxReceivedMessageSize="2147483647" messageEncoding="Text"
             textEncoding="utf-8" transferMode="Buffered"
             useDefaultWebProxy="true">
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
                    maxArrayLength="2147483647" maxBytesPerRead="2147483647"
                    maxNameTableCharCount="2147483647" />
      <security mode="None">
        <transport clientCredentialType="None" proxyCredentialType="None"
                   realm="" />
        <message clientCredentialType="UserName" algorithmSuite="Default" />
      </security>
    </binding>
  </basicHttpBinding>
</bindings>

由于省略了name属性，因此使用此配置的任何服务都将使用上述绑定配置作为来自http协议的请求的默认值，除非在特定端点元素中覆盖{ {1}}属性。

第二种方法是明确定义一个端点，并为bindingCongifuration属性分配你定义的绑定配置的名称（再次如Sajeetharan的回答所示）。

readerQuotas maxStringContentLength没有改变
