c# - WCF 为 CustomBinding 中的 HttpTransportBindingElement 修改 ReaderQuotas

Question

BasicHttpBinding 类有一个 ReaderQuotas 属性，您可以访问该属性以覆盖 MaxArrayLength、MaxBytesPerRead 等属性等

在 CustomBinding 而不是 BasicHttpBinding 中使用 HttpTransportBindingElement 时，如何访问 ReaderQuotas 以实现相同的目的>?

即:

var bindingElement = new HttpTransportBindingElement();
bindingElement.MaxBufferSize = 65536; // works
bindingElement.ReaderQuotas.MaxArrayLength = 65536; // error no ReaderQuotas member

var binding = new CustomBinding(bindingElements);
binding .ReaderQuotas.MaxArrayLength = 65536; // also no ReaderQuotas member

预先感谢您的帮助。

您需要使用消息编码绑定(bind)元素 TextMessageEncodingBindingElement 而不是 HttpTransportBindingElement:

        var bindingElement = new TextMessageEncodingBindingElement();
        bindingElement.ReaderQuotas.MaxArrayLength = 65536;

        var binding = new CustomBinding();
        binding.Elements.Add(bindingElement);

其他message encoder types (即二进制或 MTOM)可以使用，但如果你正在进行直接转换 the default for basicHttpBinding is text :

The value of WSMessageEncoding that indicates whether MTOM or Text/XML is used to encode SOAP messages. The default value is Text.
