Hi Friends,
Problem:
Recently working on one WCF project we found
one issue when we are reading PDF file from SERVER using WCF. There is error
like
System.ServiceModel.CommunicationException
: 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.
Solution:
To resolve this problem we
increased MaxReceivedMessageSize
in app.config.
We need to increase the value of
two limiting parameters: maxBufferSize and maxReceivedMessageSize. In my
example these values are set to 2147483647.
For max file size in WCF, we need
to set following parameter in binding files.
MaxBufferPoolSize gets or sets the maximum size of any
buffer pools used by the transport. The default is 524,288 bytes.
MaxReceivedMessageSize gets and
sets the maximum message size that can be receivied. The default is 65536
bytes.
ReaderQuotas: Defines the contraints on the complexity of
SOAP messages that can be processed by endpoint configured with a binding. You
need to set the maxBytesPerRead, maxDepth,
maxNameTableCharCount,maxStringContentLength.
<binding
name="MyService"
maxReceivedMessageSize="2147483647"
maxBufferSize="2147483647" transferMode="Streamed" >
<readerQuotas maxDepth="2147483647"
maxStringContentLength="2147483647"
maxArrayLength="2147483647"
maxBytesPerRead="2147483647"
maxNameTableCharCount="2147483647"/>
<!-- other binding
info here, such as security -->
</binding>
Max possible size: MaxReceivedMessageSize to 2147483647 (i.e. Int32.MaxValue), which
is 2GB
Please Note:
2. We can set it to the maximum value, which is 2GB (2147483647) - or if we’re using streamed transfers we can go up to 263 bytes (almost 10,000,000 terabytes). But remember that by setting it to a value larger than necessary we may be opening our service (or client) to attacks.
3. Only if the service is expected to receive messages larger than 65536 bytes. And in this case, we’d be increasing MaxReceivedMessageSize on the endpoints where we expect to receive such big messages.
4. If the messages that our client/servers expect to receive are larger than the default value for MaxReceivedMessageSize, then we need to increase this quota.
Happy Programming!!
