WCF MaxStringContentLength & MaxReceivedMessageSize

[ServiceContract]

public　interface　IService

{

[OperationContract]

void　Test(string　s);

}

public　class　Service　:　IService　

{

public　void　Test(string　s)

{

Console.WriteLine(s.Length);

}

}

public　class　WcfTest

{

public　static　void　Test()

{

AppDomain.CreateDomain("Server").DoCallBack(delegate

{

ServiceHost　host　=　new　ServiceHost(typeof(Service),　new　Uri("net.tcp://localhost:8080/service"));

host.AddServiceEndpoint(typeof(IService),　new　NetTcpBinding(),　"");

host.Open();

});

IService　channel　=　ChannelFactory<IService>.CreateChannel(new　NetTcpBinding(),　

new　EndpointAddress("net.tcp://localhost:8080/Service"));



using　(channel　as　IDisposable)

{

channel.Test(new　String('a',　1024　*　10));

}

}

}

 运行一下，目标出现~~~ 

　　未处理 System.ServiceModel.FaultException

 Message="The　formatter　threw　an　exception　while　trying　to　deserialize　the　message:　Error　in　deserializing　body　of　request　message　for　operation　'Test'.　The　maximum　string　content　length　quota　(8192)　has　been　exceeded　while　reading　<a href="http://tech.ddvip.com/web/xml/index.html" target="_blank">XML</a>　data.　This　quota　may　be　increased　by　changing　the　MaxStringContentLength　property　on　the　XmlDictionaryReaderQuotas　object　used　when　creating　the　XML　reader."

既然已经有了详细提示，那么我们就按照提示做。 

 AppDomain.CreateDomain("Server").DoCallBack(delegate

{
　　XmlDictionaryReaderQuotas　quotas　=　new　XmlDictionaryReaderQuotas();
　　quotas.MaxStringContentLength　=　6553500;
　　NetTcpBinding　binding　=　new　NetTcpBinding();
　　binding.ReaderQuotas　=　quotas;
　　ServiceHost　host　=　new　ServiceHost(typeof(Service),　new　Uri("net.tcp://localhost:8080/service"));
　　host.AddServiceEndpoint(typeof(IService),　binding,　"");
　　host.Open();
});
IService　channel　=　ChannelFactory<IService>.CreateChannel(new　NetTcpBinding(),　
　　new　EndpointAddress("net.tcp://localhost:8080/Service"));
　　
using　(channel　as　IDisposable)
{
　　channel.Test(new　String('a',　1024　*　10));
}

　OK！可以运行了。我们继续加大传递的字符串。 

 IService　channel　=　ChannelFactory<IService>.CreateChannel(new　NetTcpBinding(),　

　　new　EndpointAddress("net.tcp://localhost:8080/Service"));

　　

using　(channel　as　IDisposable)

{

　　channel.Test(new　String('a',　1024　*　100));

}

 哎~~ 新的异常出现了。 

　　未处理 System.ServiceModel.CommunicationException

　　Message="The maximum message size quota for incoming messages has been exceeded for the remote channel. See the server logs for more details."

　　看异常提示，这回要改的是 channel 的信息。

  

AppDomain.CreateDomain("Server").DoCallBack(delegate 

{
　　XmlDictionaryReaderQuotas　quotas　=　new　XmlDictionaryReaderQuotas();
　　quotas.MaxStringContentLength　=　6553500;
　　NetTcpBinding　binding　=　new　NetTcpBinding();
　　binding.ReaderQuotas　=　quotas;
　　binding.MaxReceivedMessageSize　=　6553500;　//　<----　Here！--------------
　　ServiceHost　host　=　new　ServiceHost(typeof(Service),　new　Uri("net.tcp://localhost:8080/service"));
　　host.AddServiceEndpoint(typeof(IService),　binding,　"");
　　host.Open();
});
IService　channel　=　ChannelFactory<IService>.CreateChannel(new　NetTcpBinding(),　
　　new　EndpointAddress("net.tcp://localhost:8080/Service"));
　　
using　(channel　as　IDisposable)
{
　　channel.Test(new　String('a',　1024　*　100));
}
