“在读取XML数据时已超出最大字符串内容长度配额（8192）”将XML字符串发送到WCF时出错

Question

I have trying everything in three days to fix this error in my application in client and server config, but nothing helps, this is my configs:

                     );

Answer 1

I found the problem! :D

The problem is in IdBookIssuerIssuedTokenBinding.CreateBindingElements() .

I had overridden and not called the base:

public override BindingElementCollection CreateBindingElements()
{
    BindingElementCollection elements = new BindingElementCollection();

    elements.Add(this.security);
    elements.Add(this.transport);

    return elements;
}

Now I am doing this:

public override BindingElementCollection CreateBindingElements()
{
    BindingElementCollection elements = base.CreateBindingElements();

    var securityBindingElement = elements.Find<SecurityBindingElement>();
    elements.Remove(securityBindingElement);
    elements.Add(this.security);

    var transportBindingElement = elements.Find<HttpTransportBindingElement>();
    elements.Remove(transportBindingElement);
    elements.Add(this.transport);

    return elements;
}

And it works like a charm!

I can't explain why I need to call base. If someone could explain in the comments, that would be great!

Answer 2

I've run into problems similar to this before. In your config file, try increasing the size for all instances of your following line (there were at least two):

ws2007HttpBinding.MaxBufferPoolSize = int.MaxValue;

Also, in your service, do the same here:

<ws2007FederationHttpBinding>
    <binding name="IDBookIssuerIssuedTokenFederation" closeTimeout="00:10:00" openTimeout="00:10:00" 
... **maxBufferPoolSize="2147483647"**

It's a wee bit counter-intuitive, but the service will barf if it receives a response that is larger than it is configured to accept.

Hope that helps!
