What is the maximum size that maxReceivedMessageSi

问题:

I noticed that 2147483647 seems to be a popular choice for maxReceivedMessageSize but is this the limit?

回答1:

Nope, the limit is Int64.MaxValue¹ which is: 9223372036854775807

回答2:

MaxMessageReceivedSize in basicHttpBinding appears to be an int32 - setting it over the max value of an int32 results in:

This factory buffers messages, so the message sizes must be in the range of an integer value. Parameter name: bindingElement.MaxReceivedMessageSize

回答3:

MaxReceivedMessageSize and MaxBufferSize must same value and MaxBufferSize is Int32.

回答4:

Use the defaults for the maximum size so one doesn't fat finger a value:

binding.MaxBufferSize          = int.MaxValue;
binding.MaxReceivedMessageSize = long.MaxValue;
