WCF MaxStringContentLength错误

Question

I making simple WCF service Server Side running on iis Client WinForms.

When I trying to send big string to server i have following exception:

The formatter threw an exception while trying to deserialize the message: Error in deserializing body of request message for operation 'CreateFolder'. The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Line 147, position 78.

client app.config:

<configuration>
  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_IService1" maxReceivedMessageSize="10000000" >
          <readerQuotas maxDepth="32" maxStringContentLength="10000000"   maxArrayLength="16384"
                    maxBytesPerRead="4096" maxNameTableCharCount="16384" />
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://192.168.15.72:7777/Service1.svc" binding="basicHttpBinding"
        bindingConfiguration="BasicHttpBinding_IService1" contract="ServiceReference1.IService1"
        name="BasicHttpBinding_IService1" />
    </client>
  </system.serviceModel>
</configuration>

Server Web config:

<?xml version="1.0" encoding="utf-8"?>

    <compilation debug="true" targetFramework="4.0" />

        maxBufferSize="10000000" >
          <readerQuotas maxDepth="32" maxStringContentLength="10000000"   maxArrayLength="16384"
                     maxBytesPerRead="4096" maxNameTableCharCount="16384" />
        </binding>

</configuration>

When i run server on localhost iis it works great. Any ideas how to solve this?

Answer 1

The binding applies to both client and service. You modified the client side correctly, but you need to do it on the server side as well.

The client sends request to server - server is doing deserialization, and your error occurs while deserializing. Everything points out that you didn't update server-side config for binding (web.config)

Answer 2

check your maxReceiveMessageSize and maxBufferSize

<binding name="BasicHttpBinding_IService1"
             maxReceivedMessageSize="10000000"
             maxBufferSize="10000000">
</binding>

they should be sufficiently large to allow your larger strings + what else is in your message
