how to make no limit on maxBufferSize and maxReceivedMessageSize

I have an ASP.NET (C#) 4.0 WCF application. I got message error:

Error : The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

I have increased it into 

maxBufferSize="2097152" maxBufferPoolSize="524288" maxReceivedMessageSize="2097152"

it works fine. But I am afraid that next time may be it will be over the quota again.

Can I set this maxBufferSize and maxReceivedMessageSize with no limit ?

thanks you in advance

You should change buffersize, if you're using dynamically use this code

 var binding = new BasicHttpBinding();
        binding.ProxyAddress = new Uri(string.Format("http://{0}:{1}", proxyAddress, proxyPort));
        binding.UseDefaultWebProxy = false;
        binding.Security.Mode = BasicHttpSecurityMode.Transport;
        binding.MaxReceivedMessageSize = Int32.MaxValue; //IMPORTANT
        binding.MaxBufferSize = Int32.MaxValue; //IMPORTANT
        binding.MaxBufferPoolSize = Int32.MaxValue;//IMPORTANT
        binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
        binding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.Basic;

if you're using webconfig use this code 

<bindings>
<basicHttpBinding>
    <binding name="basicHttp" allowCookies="true"
             maxReceivedMessageSize="20000000" 
             maxBufferSize="20000000"
             maxBufferPoolSize="20000000">
        <readerQuotas maxDepth="32" 
             maxArrayLength="200000000"
             maxStringContentLength="200000000"/>
    </binding>
</basicHttpBinding>

Can I set this maxBufferSize and maxReceivedMessageSize with no limit ?

No. You can not do that.

Set your values to Max like:

  maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"

MaxBufferSize is of type int. So the max value it can support is Int32.MaxValue (2147483647) to avail the maximum allowable size. (Int.MaxValue is just one byte shy of 2 GB of data)

MaxReceivedMessageSize on the other hand is of type long or Int64 and the max value it supports is: 9,223,372,036,854,775,807

Also, if you're maxing out your buffer with big uploads or downloads, consider streaming as an alternative.

You cannot set it to "no limit" - how would you handle a limitlessly large message, anyway?

The maximum you can set it to is 2 billion (int.MaxValue in .NET) - which corresponds to 2 GB (2'147'483'648 bytes) of data.

Is that enough for your needs?
